Cianobacterias en un cultivo de arroz (Oryza sativa L.) en Cuautla, Morelos.
Provedor de dados: 32
Autores: Escalante Vargas, Isaura.
Las cianobacterias se presentan de manera natural en los arrozales y participan en los ciclos bioquímicos del nitrógeno y carbono. Sin embargo, estudios sobre su diversidad y función en arrozales de México son escasos. Con el objetivo de registrar la riqueza de cianobacterias durante un ciclo reproductivo del cultivo del arroz, se realizaron cuatro recolectas de suelo correspondientes a cada etapa del ciclo fenológico del arroz bajo condiciones de inundación en el ejido La Calavera, Cuautla, Morelos. Se hicieron cultivos en medio agua-suelo y medio BG11 en condiciones estándar. Las especies encontradas pertenecen a los Órdenes Chroococcales, Oscillatoriales y Nostocales, su presencia está asociada a las condiciones del manejo tradicional del cultivo....

Exploring agency beyond humans: the compatibility of Actor-Network Theory (ANT) and resilience thinking
Provedor de dados: 7
Autores: Dwiartama, Angga; Centre for Sustainability, University of Otago, New Zealand; School of Life Sciences and Technology, Institut Teknologi Bandung, Indonesia; dwiartama@sith.itb.ac.id; Rosin, Christopher; Centre for Sustainability, University of Otago, New Zealand; chris.rosin@otago.ac.nz.
At first glance, the compatibility of social theory and resilience thinking is not entirely evident, in part because the ontology of the former is rooted in social interactions among human beings rather than ecological process. Despite this difference, resilience thinking engages with particular aspects of  social organization that have generated intense debates within social science, namely the role of humans as integral elements of social-ecological systems and the processes through which given social structures (including material relations) are either maintained or transformed. Among social theoretical approaches, Actor-Network Theory (ANT) is noted for its distinctive approach to these aspects. ANT proposes that human and nonhuman components (both...

Genetic diversity analysis of rice cultivars (Oryza sativa L.) differing in salinity tolerance based on RAPD and SSR markers
Provedor de dados: 69
Autores: Kanawapee,Nantawan; Sanitchon,Jirawat; Srihaban,Pranee; Theerakulpisut,Piyada.
Thirty rice cultivars were evaluated for salinity tolerance during the seedling stage and were divided into five tolerance groups including tolerant (T), moderately tolerant (MT), moderately susceptible (MS), susceptible (S) and highly susceptible (HS) which comprised 5, 10, 9, 4 and 2 cultivars respectively. Genetic diversity of all rice cultivars was evaluated using random amplified polymorphic DNA (RAPD) and simple sequence repeats (SSR) markers. The cultivars were evaluated for polymorphisms after amplification with 20 random decamer primers and 20 SSR primer pairs. A total of 161 RAPD markers and 190 SSR alleles were produced which revealed 68.94% and 89.47% polymorphism respectively. Mean genetic similarity coefficient was 0.82 for RAPD and 0.70 for...

After the success of IR8 and TN1, breeders depended heavily on these two rice cultivars for source of short stature led to the narrow genetic base to majority of present day rice varieties, as far as sd1 (semi-dwarf1) gene is concerned. In addition, analysis of genetic lineage of the majority of the cultivated rice varieties in tropical Asia reveals that sd1 from DGWG (Dee-Gee-Woo-Gen) is the major source of dwarfing gene. Such high amount of genetic homogeneity renders rice plants vulnerable to epidemic of diseases and insect pests. In the current study, we made an attempt to identify the alternate sources of DGWG allele of sd1 gene by characterizing 29 induced and 3 spontaneous dwarf accessions employing marker for DGWG allele of sd1 gene and exogenous...

Effects of 5-aminolevulinic acid (ALA)-containing supernatants from selected Rhodopseudomonas palustris strains on rice growth under NaCl stress, with mediating effects on chlorophyll, photosynthetic electron transport and antioxidative enzymes
Provedor de dados: 69
Autores: Nunkaew,Tomorn; Kantachote,Duangporn; Kanzaki,Hiroshi; Nitoda,Teruhiko; Ritchie,Raymond J.
Background: Rice is globally one of the most important food crops, and NaCl stress is a key factor reducing rice yield. Amelioration of NaCl stress was assessed by determining the growth of rice seedlings treated with culture supernatants containing 5-aminolevulinic acid (ALA) secreted by strains of Rhodopseudomonas palustris (TN114 and PP803) and compared to the effects of synthetic ALA (positive control) and no ALA content (negative control). Results: The relative root growth of rice seedlings was determined under NaCl stress (50 mM NaCl), after 21 d of pretreatment. Pretreatments with 1 &amp;#956;M commercial ALA and 10X diluted culture supernatant of strain TN114 (2.57 &amp;#956;M ALA) gave significantly better growth than 10X diluted PP803 supernatant...

Provedor de dados: 69
Autores: Pervaiz,Zahida Hassan; Rabbani,M. Ashiq; Khaliq,Ishtiaq; Pearce,Stephen R; Malik,Salman A.
Genetic diversity underlies the improvement of crops by plant breeding. Land races of rice (Oryza sativa L.) can contain some valuable alleles not common in modern germplasm. The aim here was to measure genetic diversity and its effect on agronomic traits among rice land-race genotypes grown in Pakistan. Diversity was measured using thirty-five microsatellite markers and seventy-five genotypes. Among the markers used a total of 142 alleles were detected at 32 polymorphic SSR loci, while three loci were monomorphic in Pakistani rice landraces. The number of alleles identified by each marker ranged from 2 to 13 with a mean of 4.4. Size differences between the smallest and largest alleles varied from 11bp to 71bp. Polymorphism information content ranged from...

Assessment of genetic diversity in Venezuelan rice cultivars using simple sequence repeats markers
Provedor de dados: 69
Autores: Ghneim Herrera,Thaura; Posso Duque,Duina; Pérez Almeida,Iris; Torrealba Núñez,Gelis; Pieters,Alejandro J; Martinez,César P; Tohme,Joe M.
In Venezuela, pedigree analyses indicate that the rice varieties currently under cultivation are closely related. Effective breeding programs, based on knowledge of the genetic diversity of cultivars, are needed to broaden the genetic bases of rice germplasm in the country. In this study, we used a set of 48 simple-sequence-repeat (SSR) markers to assess the genetic diversity of 11 Venezuelan rice cultivars, released by the National Rice Breeding Program between 1978 and 2007. A total of 203 alleles were detected, the number of alleles (NA) per marker ranged from 2 to 9, with an average of 4.23. The average genic diversity (H) over all SSR loci for the 18 genotypes was 0.524, ranging from 0.105 to 0.815. Positive correlations were found between H at each...

Evaluation of genetic diversity and linkage disequilibrium in Korean-bred rice varieties using SSR markers
Provedor de dados: 69
Autores: Wang,Xiao-Qiang; Kwon,Soon-Wook; Park,Yong-Jin.
Background: In order to evaluate the variation among different rice types, the genetic diversity in a rice collection composed by 59 breeding lines, 23 landraces, 18 weedy rice lines, and 35 introduced lines that collected from countries worldwide was analyzed using 134 simple sequence repeat markers. Results: In total, 1264 alleles were identified (average, 9.43 per locus). Rare alleles made up a large portion (58.4%) of the detected alleles, and 29 unique alleles associated with rice accessions were also discovered. A model-based structural analysis revealed the presence of three subpopulations. The genetic relationships revealed by the neighbour-joining tree method were fairly consistent with the structure-based membership assignments for most of the...

Iron homeostasis related genes in rice
Provedor de dados: 74
Autores: Gross,Jeferson; Stein,Ricardo José; Fett-Neto,Arthur Germano; Fett,Janette Palma.
Iron is essential for plants. However, excess iron is toxic, leading to oxidative stress and decreased productivity. Therefore, plants must use finely tuned mechanisms to keep iron homeostasis in each of their organs, tissues, cells and organelles. A few of the genes involved in iron homeostasis in plants have been identified recently, and we used some of their protein sequences as queries to look for corresponding genes in the rice (Oryza sativa) genome. We have assigned possible functions to thirty-nine new rice genes. Together with four previously reported sequences, we analyzed a total of forty-three genes belonging to five known protein families: eighteen YS (Yellow Stripe), two FRO (Fe3+-chelate reductase oxidase), thirteen ZIP (Zinc regulated...

A walk on the wild side: Oryza species as source for rice abiotic stress tolerance
Provedor de dados: 74
Autores: Menguer,Paloma Koprovski; Sperotto,Raul Antonio; Ricachenevsky,Felipe Klein.
Abstract Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase are expected to soon call for new, fast generation of stress tolerant rice germplasm, and current within-species rice diversity might not be enough to overcome such needs. The Oryza genus contains other 23 wild species, with only Oryza glaberrima being also domesticated. Rice domestication was performed with a narrow genetic diversity, and the other Oryza species are a virtually untapped genetic resource for rice stress tolerance...

Comparative linkage mapping of Oryza glumaepatula and Oryza sativa interspecific crosses based on microsatellite and expressed sequence tag markers
Provedor de dados: 74
Autores: Rangel,Priscila Nascimento; Brondani,Rosana Pereira Vianello; Coelho,Alexandre Siqueira Guedes; Rangel,Paulo Hideo Nakano; Brondani,Claudio.
Molecular linkage maps representing the rice genome have been an important tool for breeding programs because they allow the elucidation of polygenic traits and are an efficient tool for monitoring wild introgressions in interspecific crosses. Common markers among rice genetic maps are important in defining the homology of chromosomes and the synteny between genomic target regions. We used 148 markers (expressed sequence tags, microsatellites and single nucleotide polymorphisms) to construct a molecular linkage map based on co-dominant markers for an interspecific backcross population using a wild rice (Oryza glumaepatula) from Brazil and performed a comparative analysis with other interspecific maps. The comparative analysis revealed a Spearman...

DNA tagging of blast resistant gene(s) in three Brazilian rice cultivars
Provedor de dados: 74
Autores: Sandhu,S.S.; Colombo,Carlos; Bastos,Cândido R.; Siqueira,Walter J.
Rice blast is the most important fungal disease of rice and is caused by Pyricularia oryzae Sacc. (Telomorph Magnoporthe grisea Barr.). Seven randomly amplified polymorphic DNA (RAPD) markers OPA5, OPG17, OPG18, OPG19, OPF9, OPF17 and OPF19 showed very clear polymorphism in resistant cultivar lines which differed from susceptible lines. By comparing different susceptible lines, nine DNA amplifications of seven primers (OPA5(1000), OPA5(1200,) OPG17(700), OPG18(850), OPG19(500), OPG19(600), OPF9(600), OPF17(1200) and OPF19(600)) were identified as dominant markers for the blast resistant gene in resistant cultivar lines. These loci facilitate the indirect scoring of blast resistant and blast susceptible genotypes. The codomine RAPDs markers will facilitate...

A new approach for obtaining rapid uniformity in rice (Oryza sativa L.) via a 3x x 2x cross
Provedor de dados: 74
Autores: Xing,Shaochen; Cai,Yuhong; Zhou,Kaida.
A triploid (2n = 3x = 36) rice plant was obtained by screening a twin seedling population in which each seed germinated to two or three sprouts that were then crossed with diploid plants. One diploid plant was chosen among the various F1 progenies and developed into an F2 population via self-pollination. Compared with the control variety Shanyou 63, this F2 population had a stable agronomical performance in field trials, as confirmed by the F-test. The stability of the F2 population was further substantiated by molecular analysis with simple sequence repeat markers. Specifically, of 160 markers assayed, 37 (covering all 12 chromosomes) were polymorphic between the parental lines. Testing the F1 hybrid individually with these markers showed that each PCR...

Overexpression of salt-induced protein (salT) delays leaf senescence in rice
Provedor de dados: 74
Autores: Zhu,Keming; Tao,Huimin; Xu,Shuo; Li,Kaixia; Zafar,Sundus; Cao,Wei; Yang,Yanhua.
Abstract Senescence, a highly programmed process, largely determines yield and quality of crops. However, knowledge about the onset and progression of leaf senescence in crop plants is still limited. Here, we report that salt-induced protein (salT), a new gene, may be involved in leaf senescence. Overexpressing salT could prolong the duration of leaves with higher concentrations of chlorophyll compared with the wild type. Moreover, overexpression of salT could delay the senescence of rice leaves though the inhibition of senescence associated genes (SAGs). Overall, the characterization of salT suggested that it is a new gene affecting the leaf senescence induced by natural and dark conditions.

Overexpression of rice F-box protein OsFBX322 confers increased sensitivity to gamma irradiation in Arabidopsis
Provedor de dados: 74
Autores: Hwang,Jung Eun; Hwang,Sun-Goo; Jung,In Jung; Han,Sung Min; Ahn,Joon-Woo; Kim,Jin-Baek.
Abstract Ionizing radiation has a substantial effect on physiological and biochemical processes in plants via induction of transcriptional changes and diverse genetic alterations. Previous microarray analysis showed that rice OsFBX322, which encodes a rice F-box protein, was downregulated in response to three types of ionizing radiation: gamma irradiation, ion beams, and cosmic rays. In order to characterize the radiation-responsive genes in rice, OsFBX322 was selected for further analysis. OsFBX322 expression patterns in response to radiation were confirmed using quantitative RT-PCR. Transient expression of a GFP-OsFBX322 fusion protein in tobacco leaf epidermis indicated that OsFBX322 is localized to the nucleus. To determine the effect of OsFBX322...

Provedor de dados: 74
Autores: Alvarez,Alba; Fuentes,Jorge Luis; Puldón,Violeta; Gómez,Pedro Julio; Mora,Leonor; Duque,Miriam C.; Gallego,Gerardo; Tohme,Joe M.
Microsatellite polymorphism was studied in a sample of 39 traditional rice (Oryza sativa L.) varieties and 11 improved varieties widely planted in Cuba. The study was aimed at assessing the extent of genetic variation in traditional and improved varieties and to establish their genetic relationship for breeding purposes. Heterozygosity was analyzed at each microsatellite loci and for each genotype using 10 microsatellite primer pairs. Between varieties genetic relationship was estimated. The number of alleles per microsatellite loci was 4 to 8, averaging 6.6 alleles per locus. Higher heterozygosity (H) was found in traditional varieties (H TV = 0.72) than in improved varieties (H IV = 0.42), and 68% of the total microsatellite alleles were found...

As várzeas amapaenses, apesar de pouco exploradas, apresentam potencial para nelas se desenvolver uma rizicultura intensiva, com minimo de insumos, graças a deposição natural dos detritos minerais e organicos, transportados pelos rios de água barrenta em suas inundações periodicas. No entanto, a falta de cultivares adaptadas a essas formações ecologicas, associada ao baixo nível tecnológico do produtor, são alguns dos fatores responsaveis pelos baixos rendimentos obtidos com essa cultura. Com o objetivo de avaliar as características produtivas de diversas cultivares e linhagens de arroz, selecionadas em ensaios preliminares, foi conduzido um experimento no Campo Experimental de Mazagão, sob condições de várzea umida.

A época de plantio é, sem dúvida, para muitos cultivos, o fator mais discutido, havendo necessidade de se determinar o melhor método de semeio da cultura, que é influenciado diretamente pelos fatores climáticos da região. A época de semeadura do arroz no Estado do Acre é bastante indefinida, variando de setembro a dezembro. Todavia, as condições climáticas da região exigem que se precise a época ideal, uma vez que de acordo com o ciclo da cultivar, perdas substanciais poderão ser observadas no rendimento da cultura, dado o índice de precipitação pluviométrica na época da colheita, beneficiamento e transporte do produto.

Espaçamento e densidade para o cultivo do arroz de sequeiro na microrregião Alto Purus-Acre. II. Plantio em sulco.
Provedor de dados: 14
Autores: CAMPOS, I. S.; MEDEIROS, J. A.
A cultura do arroz no Acre, ainda não se reveste da importância econ6mica esperada, apesar de sua condição de cereal de alta produtividade e baixo custo de produção. Com o êxodo da população do meio rural para a cidade e outras regiões que ofereçam melhores condiç6es de trabalho, o agricultor, muitas vezes, vê-se ante o dilema de usar máquinas ou não poder realizar as diversas operações agrícolas, face a indisponibilidade ou deficiência de mão-de-obra. O sistema operacional utilizado pela maioria dos agricultores, é baseado na mão-de-obra familiar, onde considerável parte da produção obtida é consumida pela família, sendo a restante comercializada. Processos inadequados de manejo do solo e da cultura, contribuem para o decréscimo da produtividade. Apesar...

Provedor de dados: 14
Autores: EUCLIDES, V. P. B.; SILVA, J. M. da; O'DONOVAN, P. B.
No Brasil Central a producao bovina encontra-se, geralmente, associada a producao agricola. A cultura de arroz aparece frequentemente como pratica associada ao estabelecimento de pastagens. E com a criacao do Programa Nacional do Alcool espera-se uma marcada expansao do cultivo da mandioca nos proximos anos. Os produtos dessas duas culturas poderao ser de grande importancia na alimentacao de rebanhos bovinos ja que a palha de arroz e a parte aerea da mandioca podem ser utilizadas como fonte energetica e proteica, respectivamente, durante a epoca seca. O Centro Nacional de Pesquisa de Gado de Corte desenvolveu este trabalho com o objetivo de estudar a influencia de niveis de suplementacao de feno da parte aerea da mandioca sobre o consumo e digestibilidade...

El arroz en Latinoamérica y el Caribe (LAC) es un cultivo de gran importancia social y económica. El consumo de arroz en LAC ha aumentado significativamente durante los últimos años, registrando un promedio actual de 30 kg persona-1 año-1. La particularidad del arroz producido en LAC está en una alta calidad de grano y una producción que se realiza en su mayoría bajo sistemas mecanizados con siembra directa. En LAC, el arroz es producido bajo riego y secano dentro de diferentes eco-regiones (templado, tropical húmedo, tropical seco). La seguridad alimentaria y el cambio climático constituyen un reto para la producción de arroz en LAC, elevando la necesidad de aumentar, pero a su vez estabilizar los rendimientos y la calidad del grano.

Arroz e feijão intercalados em lavouras cafeeiras no Acre.
Provedor de dados: 14
Autores: OLIVEIRA, V. H. de; CAMPOS, I. S.; CARDOSO, J. E.; SALES, F. de.
A utilização de culturas de ciclo curto em cafezais novos visa principalmente reduzir seus custos de formação, garantir um melhor aproveitamento do solo, além de assegurar ao produtor um retorno do capital investido, antes da primeira colheita. Prática cultural bastante difundida na agricultura acreana, o cultivo intercalar, no entanto, ainda não dispõe de suficientes informações técnicas locais que permitam recomendá-la, de modo racional, ao produtor. Em consequência, o seu emprego tem causado, na maioria dos casos, danos que afetam a produção e produtividade do cafeeiro. Com a finalidade de obter dados para a solução desse problema, estão sendo conduzidos nos campos experimentais da Fazenda EMBRAPA, km 14 da BR-364, município de Rio Branco, experimentos...

Influência da biofertilização do solo com leguminosas no rendimento do arroz.
Provedor de dados: 14
Autores: MOURA, G. de M.; FREITAS, T. S. de.
Biofertilização do solo com leguminosas, até bem pouco denominada de adubação verde, possivelmente seja uma técnica tão antiga quanto à própria agricultura. Consiste na incorporação de massa vegetal oriunda de leguminosas, cultivadas no mesmo local ou fora dele, com a finalidade de restaurar o nível de fertilidade do solo. O emprego de leguminosas como biofertilizante oferece, entre outras vantagens, melhoria das propriedades físicas e químicas do solo, incorporação de matéria orgânica que resulta em humus e mineralização do nitrogênio e outros elementos com o consequente aumento do rendimento das culturas. O emprego desta prática contribuirá decisivamente para a melhoria da produtividade da cultura do arroz no Acre. Com o objetivo de se avaliar o efeito...

Sistemas de produção em cultivo múltiplo de arroz e milho.
Provedor de dados: 14
Autores: MOURA, G. de M.
No Acre o consórcio tradicionalmente utilizado é o de milho com o arroz, dando-se prioridade a esse último, por se tratar de uma cultura mais rentável. Estima-se que 60% da produção desses cereais no Estado é oriunda de consórcio, desconhecendo-se que fatores contribuem para sua ampla adoção e qual o grau de eficiência dessa associação, na qual ambas as culturas pertencem à família de gramíneas. A UEPAE Rio Branco instalou um experimento com as culturas de arroz e milho visando avaliar o índice de eficiência de modelo de cultivo múltiplo.

Autores: MOURA, G. de M.; LODI, N. V.
As vantagens da associação de duas culturas são regidas por princípios fundamentais que incluem fatores fisiológicos, genéticos, nutricionais e econômicos, entre outros. A maior eficiência de alguns sistemas de policultivo, em comparação com as respectivas culturas exclusivas, é explicada com base no fenômeno da "anidação", a qual é conceituada como sendo a utilização dos fatores ambientais pelos componentes do consórcio, de modo que não haja competição no uso desses recursos, ou seja, ocorre uma complementariedade no aproveitamento dos mesmos.

Uma reestruturação da cadeia produtiva do arroz no estado surge como uma opção em momento de crise e pode, num primeiro momento, não significar autosuficiência no abastecimento, mas poderá proporcionar um melhor aproveitamento do potencial que a região possui, cujos resultados irão refletir em benefícios sociais e econômicos. Para a reestruturação da cadeia produtiva do arroz em Mato Grosso do Sul, é fundamental que haja um maior entrosamento entre as indústrias e os produtores para enfrentarem os problemas de forma coletiva. Para se obter maior competitividade para a cadeia produtiva do arroz em Mato Grosso do Sul, não basta se preocupar com as técnicas de produção, pois os pontos de estrangulamentos extrapolam a produção, e, certamente, uma proposta...

Autores: CAMPOS, I. S.
A lavoura arrozeira acreana apresenta um rendimento baixo, motivado não apenas pelos sistemas de cultivo usados pela maioria dos agricultores mas principalmente, devido a pouca diversificação e inferior qualidade do germoplasma, no que tange a produtividade. Através de levantamento que vem sendo executado por esta Unidade, em contato direto com o agricultor, pode-se notar uma grande mistura varietal nas sementes utilizadas, principalmente, por aqueles não atingidos pelos serviços de revenda estadual. A introdução de novas cultivares de arroz de boa produtividade, adaptadas às condições da região, é um imperativo para elevar a produção da cultura, cujo eventual aumento que vem se observando, deve-se ao incremento na área plantada.

Autores: MIRANDA, C. H. B.; FAVARO, S. P.
This communication registers authors' impressions on the parasitism of Striga (Striga asiatica (L.) Kuntze) in Brazilian varieties of maize and dryland rice that were introduced in Mozambique. It was a rare opportunity to learn about this plant parasite in its native habitat, as it does not naturally occur in Brazil, although ecological conditions are favorable for its development. It is an important quarantine plant rigorously checked out of the country, because of the risks it poses to extensive Brazilian pasturelands and cereal cropland. We hope this report calls the due attention and helps to build up knowledge on the subject.

Autores: RODRIGUES, B.; BASSINELLO, P. Z.; BORBA, T. C. de O.; MATTA, D. H. da; STONE, L. F.; HEINEMANN, A. B.
O gessamento no grão de arroz torna-o opaco, mais quebradiço e com maior probabilidade de empapamento, portanto diminui a qualidade, além do valor de mercado. É um problema altamente influenciado por adversidades meteorológicas durante a safra. Até então, não há classificação oficial definida para a área gessada. Este estudo objetivou estabelecer uma classificação para a área gessada e determinar as variáveis climáticas que mais impactam esse defeito. Dados de quatro experimentos realizados em Porangatu, GO, e Vilhena, RO, safras 2018/2019 e 2019/2020, com 11 genótipos contrastantes, foram utilizados. A análise estatística foi dividida em três passos: 1) análise dos valores preditos da área gessada de 11 genótipos; 2) classificação dos valores preditos; e...

Autores: CAMPOS, I. S.; MEDEIROS, J. A.
O arroz é um dos principais produtos agrícolas do país, sondo cultivado em maior ou menor escala, em todas as Unidades da Federação, onde encontra condições favoráveis de clima e solo. A produtividade média do arroz no Brasil, situa-se em torno de 1.500 kg/ha, colocando-se entre os menores níveis de produtividade alcançados pelos demais países produtores.A inferior qualidade de sementes e o enfraquecimento gradativo do solo devido aos métodos rudimentares de cultivo utilizados na maior parte da lavoura arrozeira acreana, tem feito do arroz uma cultura que apresenta baixos níveis de produtividade. O presente trabalho foi orientado para introdução de tecnologias que não apenas representem novas alternativas em relação ao tradicional, mas, sobretudo o aumento...

Autores: SOUSA, I. S. F. de; FERREIRA, C. M.
Entre os diferentes aspectos culturais relacionados ao arroz e ao feijão na nossa sociedade, de imediato, o que mais chama a atenção dos especialistas é que ambos são formadores do prato básico do brasileiro e, consequentemente, caracterizadores da cultura alimentar. A partir do final do século 19, a dupla se afirmou como símbolo da alimentação nacional.De maneira geral, arroz e feijão são consumidos diariamente na refeição principal, o almoço, e, em muitos casos e de várias maneiras, têm a presença garantida à mesa do jantar. Historicamente, uma das causas da existência do arroz em terras brasileiras é a crescente globalização, sobretudo a partir do século 16, com os descobrimentos e as grandes navegações, período no qual se difundiram espécies vegetais e...

Eficiência comparativa de inseticidas no controle das pragas do arroz armazenado no Estado do Acre.
Provedor de dados: 14
Autores: FAZOLIN, M.
No Brasil, as perdas de grãos durante o armazenamento têm atingido níveis médios de 20%. No Acre, devido as precárias condições de armazenamento e os fatores climáticos favoráveis ao desenvolvimento das pragas, os níveis de perdas são superiores a 30%. Os insetos têm sido os agentes responsáveis por essas perdas, causando prejuízos quantitativos determinados pela perda de peso e prejuízos qualitativos causados pela depreciação do produto devido a presença de ovos, larvas, pupas, adultos e alterações na composição química do produto, além de facilitar o desenvolvimento de micro-organismos. Nas condições locais, 35% do arroz armazenado é atacado pelo gorgulho (Sitophilus zeamais) e 65% pela traça (Sitotroga cereealella). No controle dessas pragas alguns...

Plants constantly sense changes in their environment. When nutrient elements are scarce, plants often allocate a greater proportion of their biomass to the root system. In the present study, we characterized the early root development of rice reduced culm number (rcn) mutants under standard growth conditions. Short lateral root length was consistent in five rcn mutants, and the remaining root traits varied between the rcn mutants. Subsequently, we characterized the effects of rcn1 mutation in response to nutrient shortage. Root development, involving the elongation of seminal, crown, and lateral roots and branching of the lateral roots, was promoted in wild type in response to nutrient shortage. However, in rcn1 mutants, crown root elongation was constant...

Autores: Noldin,J.A.; Chandler,J.M.; McCauley,G.N.
Red rice is a troublesome weed in irrigated rice production and is spread through contaminated commercial rice seed and machinery. Seed dormancy is a major trait for red rice. Studies were carried out at two locations to determine red rice seed longevity in the soil of several ecotypes from four US states. Five months after burial near Beaumont, Texas only three ecotypes had viable seed (&lt;1%) when buried at 5 cm, but 9 ecotypes had viable seed after two years when buried at 25 cm. At the thirty-sixth month after burial, ecotypes Arkansas 2, Louisiana 2 and 4, Mississippi 4 and Texas 1 had viable seeds, but at less than 1%. Freshly harvested red rice seeds buried at 12 cm near College Station, TX, survived longer than seeds placed on the soil surface....

A laboratory study was conducted to investigate the allelopathic effect of aqueous extracts of plant parts of Alternanthera philoxeroides and A. sessilis and soil incorporated residues on germination and seedling growth of rice (Oryza sativa). Aqueous extracts prepared from different plant parts of Alternanthera species delayed rice germination. Alternanthera philoxeroides and A. sessilis inhibited rice germination by 9-100% and 4-49%, respectively. Germination of rice seeds was reduced with increasing concentration of aqueous leaf extracts of both weed species. Early seedling growth (root and shoot lengths) and seedling vigor index were significantly reduced by 5% aqueous leaf extract compared with distilled water treated control. Germination, root and...

INTERNATIONAL AND INSTITUTIONAL R&amp;D SPILLOVERS: ATTRIBUTION OF BENEFITS AMONG SOURCES FOR BRAZIL'S NEW CROP VARIETIES
Provedor de dados: 31
Autores: Pardey,   Philip G.; Alston,   Julian M.; Chan-Kang,   Connie; Magalhaes,   Eduardo Castelo; Vosti,   Stephen A.
In general, reported rates of return to agricultural R&amp;D are high, but questions have been raised about upward biases in the evidence.  Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil.  Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output.  If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&amp;D spending, the...

Effectiveness of Government Protective Policies on Rice Production in Iran
Provedor de dados: 31
Autores: Najafi,   Bahaeddin; Bakhshoodeh,   Mohamad.
To evaluate the government intervention effects on growth of rice production in Iran, the nominal protective rate was calculated and a Nerlove supply model was applied to a time series of 1983-1998. The results showed that in the majority of these years, producers has not been supported and therefore, redirecting the rice market is recommended. In order to get more efficient approach than the government intervention, diminishing the share of the government in the market and strengthening the private sector may be listed on the top of a list that could be regarded as a plan for making rice production profitable.

An Economic Risk Analysis of Tillage and Cropping Systems on the Arkansas Grand Prairie
Provedor de dados: 31
Autores: Hignight,   Jeffrey A.; Watkins,   K. Bradley; Anders,   Merle M.
No-till (NT) has been shown to reduce fuel, labor, and machinery costs compared to conventional-till (CT) but very few rice producers in Arkansas practice NT.  The low adoption rate is most likely due to difficulties in management but also limited information on the profitability and risk of NT.  Most rice producers are knowledgeable on NT costs savings but consider it less profitable due to yield reductions offsetting costs savings.  This study evaluates production costs, crop yields, and economic risk of both NT and CT in five rice-based cropping systems (continuous rice, rice-soybean, rice-corn, rice-wheat, and rice-wheat-soybean-wheat).  Yields, crop prices, and key input prices are simulated to create net return distributions.  Stochastic efficiency...

How Inefficient Really Are the Small-Scale Rice Farmers in Eastern India?: Examining the Effects of Microtopography on the Estimation of Technical Efficiency
Provedor de dados: 31
Autores: Fuwa,   Nobuhiko; Edmonds,   Christopher M.; Banik,   Pabitra.
We focus on the impact of failing to control for differences in land types defined along toposequence on estimates of farm technical efficiency for small-scale rice farms in eastern India.  In contrast with the existing literature, we find that those farms may be considerably more technically efficient than they appear from more aggregated analysis without such control. Farms planted with modern rice varieties are technically efficient. Furthermore, farms planted with traditional rice varieties operate close to the production frontier on less productive lands (upland and mid-upland), but significant technical inefficiency exists on more productive lands (medium land and lowland).

Technology-Climate Interactions in the Green Revolution in India
Provedor de dados: 31
Autores: McKinsey,   James W., Jr.; Evenson,   Robert E.
This paper presents a model of the Green Revolution in India, in which the development and diffusion of HYVs, the expansion of irrigation and the expansion of multiple-cropping are treated as endogenous responses to more basic investments in agricultural technology and infrastructure, as well as to climate and edaphic endowments. We incorporate explicit climate-technology interactions in the model, in order to identify climate effects on the diffusion of HYVs, irrigation and multiple-cropping, and on Net Revenue to agriculture. We find that climate affects technology development and diffusion, and that technology development and diffusion affect the impacts of climate on agricultural productivity in India.

How a National Carbon Policy Could Affect Grain Variety Selection:  The Case of Rice in Arkansas
Provedor de dados: 31
Autores: McFadden,   Brandon R.; Nalley,   Lawton Lanier; Popp,   Michael P.
This study conducts a life cycle assessment (LCA) of carbon emissions and estimates the carbon sequestered in 14 commonly sown rice varieties across the Arkansas Delta.  Given the uncertainty regarding future carbon legislation, and increased consumer and industry demand for “greener” products, this study estimates how potential carbon policies would affect rice cultivar selection Hybrid rice varieties, given their higher yield and higher yield per unit of green house gas (GHG) emission, are better positioned to take advantage of any increase in consumer demand for “greener” products and/or absorb any government policy better than conventional rice cultivars.

During the first quarter of 2008, the nominal prices of major food items have reached their highest level in nearly 50 years, while prices reached their actual level record in nearly 30 years. Indeed, prices of agricultural products rose sharply in 2006 and 2007 reported an increase more marked in the first quarter of 2008. The FAO food price index rose an average of 8% in 2006 compared to the year earlier and 24% in 2007 compared to 2006. The increase in the average index for first three months of 2008 compared to first quarter 2007 was 53%. Soaring persistent price is mainly due to vegetable oils, which rose to more than 97% during the same period, followed by cereals (87%), dairy (58%) and rice (46%).

AN EXAMINATION OF PROFIT INEFFICIENCY OF RICE FARMERS IN NORTHERN GHANA
Provedor de dados: 31
Autores: Abdulai,   Awudu; Huffman,   Wallace E.
This paper employs a stochastic frontier model to examine profit inefficiency of rice farmers in the Northern Region of Ghana using farm-level survey data. The efficiency index, based on a half-normal distribution of the stochastic error term is related to farm and household characteristics. The empirical results show that farmers' human capital represented by the level of schooling contributes positively to production efficiency, suggesting that investment in farmers' education improves their allocative performance. Access to credit and greater specialization in rice production, are found to be positively related to production efficiency. A farmer's participation in nonfarm employment and being older, however, reduce production efficiency.  Farmers...

Enduring low agricultural productivity is one of the major causes of rural poverty in South Asia. Based on a review of recent empirical studies, this paper focuses on three key questions: (1) why is agricultural productivity low in the region?; (2) what are the key constraints and opportunities for enhancing agricultural productivity; and (3) what are the effective mechanisms to improve access to key productivity enhancing technologies, factors and services. Two major points raised in the paper are: (a) improved management of land and water is important for increasing productivity, but equally important is farmers' access to non land and water-related inputs and services, which through their complementary relationships with water, increase the productivity...

Market Impacts of Adopting Herbicide-Resistant Rice in the Southern United States
Provedor de dados: 31
Autores: Fuller,   Frank H.; Annou,   Mamane Malam; Wailes,   Eric J.
Herbicide-resistant (HR) rice varieties offer U.S. rice producers a powerful tool for control of red rice infestations.  However, improved weed control can shorten crop rotations and boost yields, resulting in expanded rice production and lower domestic market prices.  Declining market returns diminish the benefits of HR rice adoption and substantially reduce net returns for nonadopters.  More competitive prices increase U.S. rice exports, causing a slight decline in world rice prices.  The dependence of the rice marketing loan program on world prices prevents loan deficiency payments from adequately offsetting producers’ market revenue losses.  U.S. consumers gain from lower rice prices.

A Dynamic Decision Model of Technology Adoption under Uncertainty: Case of Herbicide-Resistant Rice
Provedor de dados: 31
Autores: Annou,   Mamane Malam; Wailes,   Eric J.; Thomsen,   Michael R.
Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production.  Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty.  The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans.  The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

Rice versus Shrimp Production in Thailand: Is There Really a Conflict?
Provedor de dados: 31
Autores: Mekhora,   Thamrong; McCann,   Laura M.J.
Shrimp farming in Thailand has had disastrous effects on the environment in the past, which has prompted a government ban on shrimp production in inland areas.  However, a new low-salinity shrimp farming system has developed that seems to have fewer disease and environmental problems than previous systems but competes with rice production for land and water resources.  The present study found that shrimp farming exhibits increasing returns to scale and is much more profitable than rice farming, which offers opportunities for rice farmers to improve their incomes through diversification.  No evidence was found for external environmental effects of shrimp production on rice production or vice versa.  A total ban on shrimp production in rice farming areas...

Today, there is an increasing worldwide interest in assessing the potential for maintaining or increasing rice yields by reducing or eliminating the use of chemicals and by decreasing irrigation requirements. The System of Rice  Intensification (SRI) first developed in Madagascar and now being tested in many countries, is an example of such an approach. The system is based largely on organic farming principles and additional requirements for spacing and the transplanting of seedlings.

ECONOMICS OF TRADE-OFF BETWEEN UREA NITROGEN AND POULTRY LITTER FOR RICE PRODUCTION
Provedor de dados: 31
Autores: Govindasamy,   Ramu; Cochran,   Mark J.; Miller,   David M.; Norman,   Richard J.
This paper identifies optimal combinations of nitrogen in the form of urea, fresh litter and composted litter for rice production.  Traditional cost minimization techniques using data from experimental results conducted at three sites in Arkansas during 1991 have been employed.  Comparisons between different scenarios indicate that the trade-off between the use of poultry litter and urea nitrogen depends on such factors as soil fertility, the yield response to litter application and the relative prices of nitrogen and litter.  The use of litter is more economical at high target yields than at low target yields.

Transition to Decoupled Rice Support and Its Production Effects in Korea
Provedor de dados: 31
Autores: Lim,   Song-Soo.
Abolishing a nearly 50-year-old policy for rice price support, Korea adopted a new direct payment program in 2005. Making the transition to decoupled income support has been governed by the need for operative and effective income safety nets and the WTO disciplines on domestic support. The program aims to deal with over-supply of rice while guarding against the threat of income insecurity. Integrated into a target price mechanism, the fixed and variable payments compensate part of farm income loss arising from adverse market conditions. An empirical estimation based on the farm-level data is performed to test the degree of a linkage between rice support and production. The analysis suggests that rice support have only marginal influence on production with...

Philippine Rice and Rural Poverty: An Impact Analysis of Market Reform Using CGE
Provedor de dados: 31
Autores: Cororaton,   Caesar B.
This paper looks at how Philippine trade reform which consists of tariff reduction and elimination of quantitative restrictions (QR) on rice imports will affect poverty within two world trade scenarios: Doha and free world trade. The impact of Doha is very small and generates biased effects against agriculture. The impact of Philippine trade reform within the Doha agenda magnifies this biased effect, making rural households worse-off compared to urban households. However, eliminating rice QR generates a set of effects where consumer price reduction dominates nominal income decline. Thus, real income improves and poverty declines across household groups, but the net effects are lower in rural than in urban households. The impact of a free world trade...

BIOFORTIFICATION, AN ALTERNATIVE TO REDUCE FOOD INSECURITY AND ITS ADVERSE EFFECTS IN DEVELOPING COUNTRIES: A HONDURAS CASE STUDY
Provedor de dados: 31
Autores: Perez Suarez,   Salomon.
Food insecurity can generate nutritional problems such as iron deficiency anemia, which in countries like Honduras is a moderate public health problem. The AgroSalud project is enhancing the iron content of beans and rice in order to improve the iron intake of vulnerable groups, especially children under five years and pregnant women. Iron- biofortified rice and beans together can reduce the deficit in iron intake by more than a 100% depending on the age group, farmer adoption and other variables. This, in turn, would increase the number of healthy (disability-adjusted life years, DALYs) years that the Honduran population could live.

Autores: Rakotoarisoa,   Manitra A.
This study determines how production and trade policy distortions affected rice productivity in thirty-three rice-producing countries.  A rice-productivity index for each country is constructed, and a model linking the productivity gap with policy distortions is presented.  After controlling for the differences in infrastructure, openness, and human capital, this article shows that high subsidies and protection in developed countries combined with taxation of rice farming in poor countries have widened the gap in rice productivity between rich and poor rice countries.

Tariff escalation is an important aspect of protection for domestic milling industries, particularly in Central America. The United States exports over 40 percent of its rice as paddy. This study uses a spatial equilibrium trade model to evaluate the impacts of tariff escalation on U.S. and global long grain paddy and milled rice trade.  Tariffs are harmonized for paddy and milled rice at two levels: milled tariff rates and zero.  The results indicate that tariff escalation distorts US rice trade in favor of paddy exports, reducing the demand for rice milling and associated value-added activities in the US.

Commercial rice imports have accounted for approximately 61%, food aid in rice accounted for about 2%, and domestic rice accounted for some 37% per annum of rice consumption in Ghana over the four years between 2000 and 2003. Compared to the 1990s, these figures show a gradual decline in the share of local rice production in the total quantities of rice consumed in the country. On the other hand, the proportion of food aid in rice consumed has remained relatively constant over the period, while the proportion of commercial imports has increased steadily. Using the Engel-Granger residual-based co-integration test, a market integration analysis was explored for imported rice and domestic rice which compared a central market for imported rice and five key...

The previous threshold used for assisting in rice stink bug spray decisions lacked flexibility in economic and production decision variables and neglected the dynamics of the pest population.  Using stochastic dynamic programming, flexible economic thresholds for the rice stink bug were generated.  The new thresholds offer several advantages over the old, static thresholds, including increased net returns, incorporation of pest dynamics, user flexibility, ease of implementation, and a systematic process for updating.

DETERMINANTS OF TECHNICAL EFFICIENCY AND VARIETAL-GAP OF RICE PRODUCTION IN NIGERIA: A META-FRONTIER MODEL APPROACH
Provedor de dados: 31
Autores: Ayinde,   Opeyemi Eyitayo; Adewumi,   Matthew Olaniyi; Ojehomon,   Vivian E.T.
This study uses the concept of meta-frontier function to examine the technical efficiency and varietal-gap of rice production in Nigeria. A random sample of 675 farmers was selected from three out six geographical zones in Nigeria. The farmers in this study were classified into three groups according to the variety of rice they planted. The three main varieties of rice planted are local (Ofada), improved (Mai-Nasara) and New Rice for African (NERICA). The technical efficiency indices were computed using the meta-frontier approach because production varieties and technologies were expected to differ between the three varieties. This method allows the measure of the varietal-differences which is the Technology Gap Ratio (TGR). Estimates of the frontier were...

The relationship between spatial price transmission and geographical distance: the case of Brazil
Provedor de dados: 31
Autores: Hernandez-Villafuerte,   Karla Vanessa.
The objectives of this research are to investigate the influence of geographical distance on the cointegration relationship in order to increase knowledge on the issue, and to indentify its role in Brazilian agricultural markets. With this intention, the cointegration framework is applied allowing for the presence of multiple structural breaks in the long run equation. The inclusion of breaks is in response to the multiple changes of the agricultural system during the period of investigation. The spatial integration is calculated between each market pair. The cointegration coefficient and geographical distance relationship is calculated by means of an OLS regression, taking into account the quality of roads and the proximity to a border or port. The effect...

Rice Trade Policies and Their Implications for Food Security
Provedor de dados: 31
Autores: Durand-Morat,   Alvaro; Wailes,   Eric J.
There is a strong linkage between the behavior of the rice market and the state of food security in many regions around the world, particularly in Asia, as made evident in the 2007-08 commodity crisis. Rice is a staple for the majority of the population in Asia, where roughly 60% of the close to one billion undernourished people live (FAO, 2010). As Timmer (2010) states, “it is impossible to improve food security in the short run or long run without providing adequate supplies of rice that are accessible to the poor” (p. 2). The rice crisis of 2007-08 showed the crucial role of export and import policies on the behavior of the rice market and its consequences for price stability and food security. Market fundamentals could only explain a minimal part of...

Impact of Zero Tillage in India's Rice-Wheat Systems
Provedor de dados: 31
Autores: Laxmi,   Vijay; Erenstein,   Olaf; Gupta,   Raj K.
To date, the most widely adopted resource conserving technology (RCT) in the Indo-Gangetic Plains (IGP)has been zero-tillage (ZT) for wheat after rice, particularly in India. This report reviews and synthesizes the experience with zero tillage in the Indian IGP. Zero tillage of wheat after rice generates significant benefits at the farm level, both in terms of significant yield gains (6–10%, particularly due to timelier planting of wheat) and cost savings (5–10%, particularly tillage savings). These benefits explain the widespread interest of farmers and the rapidity of the diffusion across the Indian IGP, further aided by the wide applicability of this mechanical innovation. The study  subsequently reports on the findings of village-level focus-group...

Autores: Watkins,   K. Bradley; Hignight,   Jeffrey A.; Anders,   Merle M.
This study evaluated the impacts of farm size and stochastic return variability on no-till (NT) rice profitability at the whole-farm level. Mixed integer programming was used to determine optimal machinery complements, fuel consumption, and machinery labor requirements for conventional till (CT) and NT rice-soybean farms of 1200, 2400, and 3600 acres in size. Crop yields, market prices, and prices for key production inputs were simulated to construct stochastic whole-farm net returns for each farm size under CT and NT management, and both first and second degree stochastic dominance analysis were used to rank cumulative distribution functions of whole-farm returns according to specified risk preferences. The results indicate NT farms exhibit second degree...

Moga District in Punjab, India, is a microcosm of the twin story of irrigation-induced growth and stress. The groundwater consumptive water use in agriculture exceeds the recharge by a substantial margin. Rice production contributes to a major part of this difference. The groundwater depletion is so critical that diversifying agriculture is the only way forward for sustainable agricultural growth. Reducing the rice area and intensifying milk production will be a win-win situation for both the farmers and the area reeling with a groundwater crisis.

RELATIONSHIP BETWEEN SPATIAL PRICE TRANSMISSION AND GEOGRAPHICAL DISTANCE IN BRAZIL
Provedor de dados: 31
Autores: Hernandez-Villafuerte,   Karla Vanessa.
The price transmission between markets is often interpreted as providing insights into the market’s infrastructure efficiency and transaction costs. Thus, finding a possible explanation for the degree of integration has become an issue of special interest. Recent researchers have pointed out the distance between markets as one of the possible factors. However, the distance is closely related with other elements, such as road quality and the proximity to an export point, which affect transport costs, opportunity costs and thus the integration. Therefore, what the most important factor is when determining the relationship among markets remains unclear. The cointegration framework, OLS and principal component regressions are applied in order to investigate...

Enhancing Farm Profitability through Portfolio Analysis: The Case of Spatial Rice Variety Selection.
Provedor de dados: 31
Autores: Nalley,   Lawton Lanier; Barkley,   Andrew P.; Brad,   Watkins; Hignight,   Jeffrey A.
The objectives of this paper is to use the large depth of existing literature on portfolio theory and apply it to rice varietal selection for 6 counties in the Arkansas Delta. Results based on 1999-2006 data suggests that combining available varieties using portfolio theory could have increased profits from 3 to 26% (dependent on location) in the Arkansas Delta. The major implication of this research is that data and statistical tools are available to improve the choice of rice varieties to plant each year in specific locations within Arkansas. Specifically, there are large potential gains from combining varieties that are characterized by inverse yield responses to growing conditions such as drought, pest infestation, or the presence of a specific disease.

This paper investigates the roles of industrial cluster on the efficiency of rice milling and the improvement of milled rice quality. The data were obtained in Kumasi area, central Ghana because the enhancement of domestic rice production is a urgent policy issue in this country, but little attention has been paid to the roles of clusters in post-harvest processing and marketing. Among 63 rice millers interviewed in the Kumasi area, 24 millers form a few clusters in the city of Kumasi, while others are scattered over 25 satellite towns around Kumasi, which enables us to examine the effect of the cluster. Regression analyses reveal that rice millers in the Kumasi clusters tend to adopt more advanced technology, and that the innovation increases milling...

Conflict between the short run welfare of poor consumers and agricultural production incentives creates some of the most difficult policy issues facing developing countries. Resulting policy option constraints are particularly severe in very low income countries. The conflict may on the one hand impede the growth in al production essential to improve long term welfare of low income consumers, and on the other hand restrain policies to increase consumption, which in the long run is essential to the success of the measures taken to increase production. The widely observed phenomenon of urban bias in food price policy is itself a product of the nature of low income societies and of this complex conflict.

NONCOMPETITIVE PRICING AND EXCHANGE RATE PASS-THROUGH IN SELECTED U.S. AND THAI RICE MARKETS
Provedor de dados: 31
Autores: Yumkella,   Kandeh K.; Unnevehr,   Laurian J.; Garcia,   Philip.
A "pricing to market" international trade model is applied to U.S. and Thai rice exports to high and middle income countries that are continuous rice importers.  These markets are characterized by strong quality preferences and highly inelastic demand, and thus exporters may exercise market power.  Evidence of noncompetitive pricing either through price discrimination across destinations or through imperfect exchange rate pass-through is found in this small but growing segment of the international rice trade.

Econometric analysis on economies of scale: An application to rice and shrimp production in Thailand
Provedor de dados: 31
Autores: Mekhora,   Thamrong.
Shrimp production in Thailand has historically been undertaken in the saline and brackish waters of coastal mangroves. In recent years rising demand and prices for shrimp and falling productivity of mangrove areas have motivated an expansion of shrimp production into the fresh-water margins of river estuaries that were previously used for rice cultivation. Generalised additive models, which offer a comprehensive approach to regression analysis, are mainly used for empirical analysis, and model development and specification for rice and shrimp production in this study. This paper presents a brief introduction to generalised additive models, discusses how they are applied to develop cost functions to satisfy the restriction of production theory, and...

This study documents the adoption and impacts of zero-tillage (ZT) wheat in the ricewheat systems of Pakistan’s Punjab province primarily drawing on a detailed empirical survey of 458 rice-wheat farmers. Our random stratified sample revealed 19% to be ZT wheat adopters and a similar share of the wheat area in the surveyed communities to be under ZT. The study suggests that diffusion has stagnated and also flags the issue of disadoption (14%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values. ZT drastically reduces tractor operations in farmers’ ZT wheat fields from an average of 8 passes to a single pass, implying a saving of 7 tractor hours and 35...

A serious concern has been raised recently on the long run sustainability of the productivity effects of Green Revolution technologies in the light of decelerating trend in the yield growth of rice since the mid 1980s under irrigated ecosystem. However, the changes in physical yield are not true measures of productivity from efficiency perspective. Total factor productivity (TFP) is a true measure of economic efficiency of any technology impact. The paper addresses the crucial issue of "is green revolution vanishing" empirically by analyzing TFP for rice in India.

Partial Reform of World Rice Trade: Implications for the U.S. Rice Sector
Provedor de dados: 31
Autores: Haley,   Stephen L.
This paper analyzes the consequences for the United States of a partial reform of world rice trade. It is argued that likely trade reform would occur in the japonica rice producing countries of Japan, South Korea, Taiwan, and the European Community. Multilateral rice trade liberalization would have strong effects for medium grain rice in the United States. The strength of these effects might not be felt for a couple of years after the liberalization has begun because of minimal Japanese imports in the first couple of years of liberalization. U.S. rice millers will likely benefit more than producers. California producers would be the major beneficiaries of more open world rice markets.

The aim of this paper is to determine Korean consumers’ valuation for domestic rice and imported rice from China and the US. Using revealed preference data from random nth price auction mechanism, our results generally suggest that consumers’ willingness to pay (WTP) for domestic rice is higher than the WTP for imported rice. Results also suggest that while country of origin and food miles information positively influences consumers’ WTP for domestic rice, country of origin information provides higher valuation for domestic rice than food miles information. Country of origin and food miles information has no statistically significant effect on WTP for the imported Chinese rice product but food miles information has a negative effect on WTP for the imported...

In the Philippines, where rice is considered the most important food crop, attempts to influence rice prices have been prevalent. The government, through National Food Authority (NFA) has sought to establish stocks and control imports to stabilize prices since its establishment in 1972 to support farm gate prices and reduce retail price of rice. But data shows divergence in retail prices and farm prices since mid 1960s. In this paper, we use vector autoregression (VAR) to analyze the movement of Philippine rice margins with government stocks and weather supply shocks to able to determine government effectiveness in actual times of market stress. Comparing VARs across regions, we are able to identify the regions in which price margins are significantly...

Decoupled Payments and Agricultural Policy Reform in Korea
Provedor de dados: 31
Autores: Lim,   Song-Soo.
Abolishing a nearly 50-year-old policy for rice price support, Korea adopted a new direct payment program in 2005. Making the transition to decoupled income payments has been governed by the need for operative and effective income safety nets and the WTO disciplines on domestic support. The program aims to deal with over-supply of rice while guarding against the threat of income insecurity. Integrated into a target price mechanism, the fixed and variable payments compensate part of farm income loss arising from adverse market conditions. Besides, the government launched a public stockholding measure to ensure food security. A review of previous studies highlights the fixed payment has no or at most minimal effects on production while the variable payment...

Using the Agricultural Resource Management Survey (ARMS) we analyze factors associated with participation in conservation, recreation and agri-tourism activities as a function of farm structure, farm financial measures, production practices, and socio-demographic characteristics of the farm operator. To estimate the functional...

Out migration from rural areas is increasingly becoming a strategy to get out of poverty. While rice–based agriculture remains to be the backbone in Southeast Asia, majority of the farming households particularly those who produce rice under rainfed conditions remain poor and insecure. This paper examines the relationship between migration and other socio-economic factors on household income using data from 1,874 rice sample farming households in Vietnam (north and south), Thailand (northeast) and Philippines (Luzon island). In the Philippines, remittances contribute about 60 per cent of household income of recipient families. In Thailand and Vietnam, these constitute about 40 per cent of total household income. International migration is most prevalent in...

Adoption of New Seed Varieties Under Production Risk: An Application to Rice in Iran
Provedor de dados: 31
Autores: Bakhshoodeh,   Mohamad; Shajari,   S.
This paper focuses on linkage between new rice seed varieties and production risk and also factors affecting adoption of these varieties in Iran. Farm-level data were collected from a sample of 154 rice farms located in two major districts of Fars province in Southern Iran for 2001-02. The risk-premium associated with the use of seed is estimated following by analyzing a moment-based production risk approach. The results show that the risk premium increases with new seed varieties in the lack of appropriate production conditions implying that new seed varieties is a riskincreasing input and involves a higher cost of risk. However, under suitable production conditions, the cultivation of new rice varieties on average ensures greater yield and at the same...

Adoption and impacts of zero tillage as a resource conserving technology in the irrigated plains of South Asia
Provedor de dados: 31
Autores: Erenstein,   Olaf; Farooq,   Umar; Malik,   R.K.; Sharif,   Muhammad.
The recent stagnation of productivity growth in the irrigated areas of the Indo-Gangetic Plains of South Asia has led to a quest for resource-conserving technologies that can save water, reduce production costs and improve production. The present synthesis of two detailed country studies confirmed widespread adoption of zero tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State (34.5% of surveyed households) and Pakistan’s Punjab province (19%). The combination of a significant “yield effect” and “cost-saving effect” makes adoption worthwhile and is the main driver behind the rapid spread and widespread acceptance of ZT in Haryana, India. In Punjab, Pakistan, adoption is driven by the significant ZT-induced cost savings for wheat...

Indian Wheat and Rice Sector Policies and the Implications of Reform
Provedor de dados: 31
Autores: Landes,   Maurice R.; Jha,   Shikha; Srinivasan,   P.V.
During 1998-2002, India experienced record public surpluses of wheat and rice, sharply higher government grain subsidy outlays, and declining per capita consumption of wheat and rice. By 2006, despite continued high subsidies and sluggish domestic consumption, India developed a large wheat deficit because of reduced price incentives, weak yield growth, and rising subsidized consumption. The pronounced market cycles and declining per capita consumption for India’s major food staples are creating pressure for Indian policymakers to adjust longstanding policies. While there has been no political consensus on more fundamental reform, recent policy changes have moved toward better targeting of food subsidies to low-income consumers, decentralization of...

Autores: Alston,   Julian M.; Pardey,   Philip G.; Chan-Kang,   Connie; Magalhaes,   Eduardo Castelo; Vosti,   Stephen A.
In general, reported rates of return to agricultural R&amp;D are high, but questions have been raised about upward biases in the evidence.  Among the reasons for this bias, insufficient attention to attribution aspects-matching of research benefits and costs-is a pervasive problem, the magnitude of which is illustrated here with new evidence for Brazil.  Over the period 1981 to 2003, varietal improvements in upland rice, edible beans, and soybeans yielded benefits attributable to research of $14.8 billion in present value (1999 prices) terms; 6.1 percent of the corresponding value of crop output.  If all of those benefits were attributed to Embrapa, a public research corporation accounting for more than half Brazil's agricultural R&amp;D spending, the...

Global Market Shocks and Poverty in Vietnam: The Case of Rice
Provedor de dados: 31
Autores: Coxhead,   Ian A.; Linh,   Vu Hoang; Tam,   Le Dong.
World food prices have experienced dramatic increases in recent years. These “shocks” affect food importers and exporters alike. Vietnam is a major exporter of rice, and rice is also a key item in domestic production, employment and consumption. Accordingly, rice price shocks from the world market have general equilibrium impacts and as such, their implications for household welfare are not known ex ante. In this paper we first present a simple framework for understanding the direct and indirect welfare effects of a global market shock of this kind. Second, we quantify the transmission of the price shock from global indicator prices to domestic markets. Third, we then we use an applied general equilibrium (AGE) model to simulate the effects of domestic...

INCREASES IN DEMAND FOR FOOD IN CHINA AND IMPLICATIONS FOR WORLD AGRICULTURAL TRADE
Provedor de dados: 31
Autores: Koo,   Won W.; Lou,   Jianqiang; Johnson,   Roger G.
China is experiencing rapid economic growth, resulting in increased demand for food. Estimates are made of Chinese production and consumption of rice, wheat, corn, and soybeans to the year 2005. Results indicate that China will become a large net importer especially of wheat, corn, and soybeans. China's grain shipping and handling industries will need to be expanded to handle the increased imports.   Note: Figures are not included in the machine readable copy--contact the authors for more information.

Adoption and Impacts of Zero-Tillage in the Rice-Wheat Zone of Irrigated Haryana, India
Provedor de dados: 31
Autores: Erenstein,   Olaf; Malik,   R.K.; Singh,   Sher.
This study documents the adoption and impacts of zero-tillage (ZT) wheat in the rice-wheat systems of India’s Haryana State primarily drawing on a detailed empirical survey of 400 rice-wheat farmers. Our random stratified sample revealed 34.5% to be ZT wheat adopters and a quarter of the wheat area in the surveyed communities to be under ZT. The study suggests the potential for further diffusion but also flags the issue of disadoption (10%). ZT adopters, non-adopters, and disadopters differ significantly in terms of their resource bases, with adopters typically showing the most favorable values. ZT drastically reduces tractor operations in farmers’ ZT wheat fields from an average of 8 passes to a single pass, implying a saving of 6 tractor hours and 36...

Valuing water in irrigated agriculture and reservoir fisheries:  A multiple-use irrigation system in Sri Lanka
Provedor de dados: 31
Autores: Renwick,   Mary E.
Although irrigation projects often provide water for more than crop irrigation, water allocation and management decisions often do not account for nonirrigation uses of water. Failure to account for the multiple uses of irrigation water may result in inefficient and inequitable water allocation decisions. Decision-makers often lack information on the relative economic contributions of water in irrigation and nonirrigation uses. This report addresses this problem. It examines the relative economic contributions of irrigated agriculture and reservoir fisheries in the Kirindi Oya irrigation system, located in southeastern Sri Lanka. The results of the analysis indicate the importance of both irrigated paddy production and reservoir fisheries to the local...

Attention to organic fertilizer has been increasing but opinions are mixed as to its impacts. This paper explores the potential and limitations of the use of farmyard manure (FYM) for paddy and upland cereals under different soil conditions in Tamil Nadu, India, using farming households’ three-year rotating panel data from 1993 to 2003. Estimated yield functions reveal that a direct impact of FYM application exists only for upland cereals but not for paddy. Meanwhile, an indirect impact through an increase in the marginal product of chemical fertilizer is observed for both paddy and upland cereals, especially under low inherent soil fertility status. Reflecting the existence of the benefit of FYM application, our factor demand estimation shows that farmers...

The Role of ICT-based Market Information Services in Spatial Food Market Integration: The Case of Malawi Agricultural Commodity Exchange
Provedor de dados: 31
Autores: Katengeza,   Samson P.; Mangisoni,   Julius H.; Okello,   Julius Juma.
The government of Malawi in 2004 initiated an ICT-based Malawi Agricultural Commodity Exchange (MACE), a market information service project, to improve access by farmers to market information. MACE was intended to improve the efficiency of agricultural markets as part of the strategy to improve food security. This study uses quantitative methods to examine whether MACE has contributed to efficiency of rice markets in Malawi. It especially tests if MACE has contributed to spatial integration of rice markets. As hypothesized, the study finds that the tendency of rice prices to move together in spatially separated markets has significantly increased since the implementation of MACE. It concludes that ICT-based market information services improve the...

Understanding the impacts of the Uruguay Round (UR) Agreement on southern commodities serves as a starting point to assess the potential impacts of the next global trade negotiations in terms of hope (expanding export markets) and fear (new competition).  Key issues examined include whether or not the UR Agreement resulted in new markets or new competition for key southern commodities-cotton, poultry, tobacco, and rice.  For new markets, export data were analyzed to determine if exports increased since the passage of the UR Agreement in 1994.  Also, countries that are leading world importers of these southern commodities were identified and data analyzed to determine whether the U.S. is exporting to these top markets.  Alternatively, to assess whether the...

This paper presents an empirical case study about farmer management of rice genetic resources in two communities of Nepal, drawing on interdisciplinary, participatory research that involved farmers, rice geneticists, and social scientists. The decision-making process of farm households is modelled and estimated in order to provide information for the design of community-based conservation programs. A bivariate model with sample selection treats the simultaneous process of whether farmers decide to plant landraces or modern varieties, and whether the landraces they choose to plant constitute genetic diversity of interest for future crop improvement. Findings show that the two landrace choices are affected by different social and economic factors. The...

The occurrence of low night temperatures during reproductive development is one of the factors most limiting rice yields in southern Australia. Yield losses due to cold temperature are the result of incomplete pollen formation and subsequent floret sterility. Researchers have found that in 75% of years, rice farmers suffer losses between 0.5 and 2.5 t/ha. Research is being undertaken to identify overseas rice varieties, that are cold tolerant under the local weather conditions and by using those genotypes as parent material, develop cold tolerance varieties of rice. A yield simulation model was used to measure reduction in losses due to cold at different minimum threshold temperatures, while the SAMBOY Rice model was used to measure the costs and returns...

This paper analyzes how Cambodian farmers and the government can respond to the rise of rice price. The study estimates rice production response in Cambodia using the Cambodia Socio-Economic Surveys (CSES) conducted in 2004 and 2007. The results indicate that agricultural productivity is far from its potential and can be increased substantially by using modern technology and inputs such as fertilizers and irrigation. Our findings also suggest that the Cambodian government needs to design its investment strategy to relax constraints in rural infrastructure such as transportation and electricity in order to increase its agricultural production and productivity and boost farmers’ income.

We find that productive efficiency declined by 7 to 22 percent during the crisis, largely because of a decline in technical efficiency and a relatively large volatility in efficiency (the coefficient of variation was larger by a factor of 1.87). Allocative efficiency, on the other hand, increased slightly and offset part of the decrease in technical efficiency. The magnitude of the impact on efficiency depended on farmers' input adjustments. Factors associated with higher levels of technical and allocative...

Whole-Farm Evaluation of No-Till Profitability in Rice Production using Mixed Integer Programming
Provedor de dados: 31
Autores: Watkins,   K. Bradley; Hill,   Jason L.; Anders,   Merle M.; Windham,   Tony E.
Rice production in Arkansas usually involves intensive tillage. No-till rice has been studied, but the focus has been limited to impacts on yields and per acre returns. This study uses mixed integer programming to model optimal machinery selection and evaluate whole-farm profitability of no-till management, for rice-soybean farms. Results indicate that lower machinery ownership expenses combined with lower fuel and labor expenses do enhance the profitability of no-till management, but the monetary gains appear to be modest, implying that other incentives may be necessary to entice producers to use the practice.

Determinants of Rice Variety Diversity on Household Farms in the Terai Region of Nepal
Provedor de dados: 31
Autores: Joshi,   Ganesh R.; Bauer,   Siegfried.
Crop genetic resources are the building block of sustainable agricultural development as these can be used to develop crop varieties adaptable to heterogeneous environmental conditions. Nepal is considered the center of origin and diversity for Asian rice, which still has many landraces. However, there has been continuous loss of genetic diversity and concern over it has grown in recent years. The main objective of this paper is to identify the determinants of variety diversity on-farm in the rainfed ecosystem of Nepal by using two-limit Tobit procedure. The diversity on farm appeared to be quite high evaluated based on the number of named varieties grown by the farmers. Majority of the farmers cultivated both modern varieties and landraces simultaneously...

2011 Updated Arkansas Global Rice Model
Provedor de dados: 31
Autores: Wailes,   Eric J.; Chavez,   Eddie C.
The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework.  The model is disaggregated by five world regions: Africa, the Americas, Asia, Europe, and Oceania.  Each region includes country models which have a supply sector, a demand sector, a trade, stocks and price linkage equations.  All equations used in this model are estimated using econometric procedures or identities.  Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which countries intervene in their rice sector economy.  Individual country...

This study has evaluated the superiority of resource conservation technologies (RCTs) over conventional methods of cultivation and has identified the factors influencing adoption of these technologies. It has provided succinct evidences from four states — Bihar, Haryana, Punjab and Uttar Pradesh — by comparing the adopters and non-adopters of RCTs in the rice-wheat cropping system of the Indo-Gangetic Plains of India. The study has highlighted superiority of RCTs over the conventional practices in terms of cost saving and efficient inputs-use. However, there is a need to internalize the RCTs in their totality by applying plans and strategies based on local dynamics. The study has suggested the need of policy formulations for dissemination and wider...

Taking a New Look at Empirical Models of Adoption: Average Treatment Effect Estimation of Adoption Rates and their Determinants
Provedor de dados: 31
Autores: Diagne,   Aliou.
This paper shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random. It is proved that instead the sample adoption rate is a consistent estimate of the population joint exposure and adoption rate, which does not inform about adoption per se. Likewise, it is shown that a model of adoption with observed adoption outcome as dependent variable and where exposure to the technology is not observed and controlled for cannot yield consistent estimates of the determinants of adoption. Such model can at best provide consistent estimates of the effects of the included explanatory variables on joint exposure and adoption. Even for that to be possible, the model must be explicitly specified as...

Measuring the Stochastic Monetary Benefits of Multiple Inlet Irrigation in Arkansas Rice Production
Provedor de dados: 31
Autores: Watkins,   K. Bradley; Hristovska,   Tatjana; Anders,   Merle M.
Irrigation fuel costs represent a significant portion of rice production expenses. Multiple inlet (MI) irrigation represents a water saving alternative to conventional flood irrigation. This study uses simulation to calculate the range of monetary benefits to MI in rice production. Water savings from MI relative to conventional flood irrigation along with rice yields, rice prices, and prices for key production inputs (diesel and fertilizer) are simulated, and stochastic rice net returns above variable and fixed expenses are calculated for different pump lifts with and without MI. Monetary benefits to MI are measured as the difference in net returns with and without MI. The results indicate MI monetary benefits depend greatly on pump lift and the presence...

Autores: Singh,   Rajinder Pal; Brennan,   John P.; Lacy,   John; Steel,   Felicity.
Ricecheck, a best management practices extension program for rice production in Australia, was developed by the NSW Department of Primary Industries advisory staff, Finley, in 1986. The program is based on eight best management practice recommendations called ‘Key Checks’ that are considered essential for achieving high yields. Economic analysis of the program reveals that there are significant financial, social and environment benefits from the adoption of the program. The results further reveal that the funds invested since 1986 by both NSW Department of Primary Industries and the Rural Industries Research and Development Corporation have been sound investments.

Have Recent Increases in International Cereal Prices Been Transmitted to Domestic Economies? The Experience in Seven Large Asian Countries
Provedor de dados: 31
Autores: Dawe,   David.
International cereal prices (in US dollar terms) have been increasing since 2003, but it is domestic prices that affect food consumption and production. This paper analyzes, for seven large Asian countries, the extent to which domestic prices have increased since 2003 and presents several conclusions. First, the data show that the increases in world cereal prices have been accompanied by a real depreciation of the US dollar. For many countries (but not all), this depreciation has neutralized a substantial proportion of the increase in world prices. Second, domestic commodity specific policies in several of these Asian countries have further stabilized domestic prices relative to the change in world prices. This has been especially true for rice, the main...

SPATIAL PATTERNS OF CROP YIELDS IN LATIN AMERICA AND THE CARIBBEAN
Provedor de dados: 31
Autores: Wood,   Stanley; You,   Liangzhi; Zhang,   Xiaobo.
From a theoretical perspective crop yields should tend to converge over time and space as: growth in yield potential exhibits diminishing returns; an increasing share of farmers shift to using high yielding varieties (HYVs); barriers to the free flow of knowledge and information are removed; and significant investments continue to be made in supporting institutions whose mandates include facilitating and accelerating the cross-border flow of improved agricultural technologies. Using a new, sub-national crop yield database for Latin America and the Caribbean (LAC) we examine whether convergence is indeed occurring, and discover it is not. On the contrary, there is evidence of divergence. We test three hypotheses that might help account for this finding:...

Out migration from rural areas is increasingly becoming a strategy to get out of poverty. While rice–based agriculture remains to be the backbone in Southeast Asia, majority of the farming households particularly those who produce rice under rainfed conditions remain poor and insecure. This paper examines the relationship between migration and other socio-economic factors on household income using data from 1,874 rice sample farming households in Vietnam (north and south), Thailand (northeast) and Philippines (Luzon island). In the Philippines, remittances contribute about 60 per cent of household income of recipient families. In Thailand and Vietnam, of the total household income, about 40 per cent are from remittances.

THE RESPONSIVENESS OF U.S. RICE ACREAGE TO PRICE AND PRODUCTION COSTS
Provedor de dados: 31
Autores: Salassi,   Michael E.
Ordinary least squares and seemingly unrelated regression procedures were used to analyze the impacts of changes in rice prices and production costs on U.S. rice planted acreage. National and regional response models were estimated over the 1970-92 period. Supply-inducing prices of rice were estimated as a function of effective rice support prices and seasonal average market prices. Expected production costs per acre were estimated using lagged actual total variable cash production expenses per acre adjusted by the previous 3-year average annual change in variable expenses. Estimated short-run price and production cost elasticities were found to be inelastic at the national level. However, the magnitude of the production cost elasticities were found to be...

Correction of the distorted structure of related prices and prevention of wide fluctuations in the level of commodity prices constitute twin challenges in agricultural price policies. While macroeconomic instruments are comprehensive sectoral analysis of prices relations, stock requirements, market integration, and various other factors that destabilize supply and demand. IFPRI’s initial analyses of price stabilization were limited to the issue of optimal stock of foodgrains. Thomas Pinckney’s work on stock policies in Kenya and Pakistan and Raj Krishna and Ajay Chhibber’s research on India have demonstrated how optimal stock policies can save scarce public resources so urgently required for economic development.

Autores: Yang,   Min-Hsien; Blandford,   David.
We examine current rice policies in four major Asian countries (China, Japan, Korea, and Taiwan), their relationship to current WTO disciplines, and to those proposed under the Doha negotiations. WTO disciplines have prompted some changes in rice policies, but disciplines of domestic support are unlikely to impose serious constraints in the future. Using the example of Taiwan, we examine how existing support policies could be changed to reduce domestic distortions and satisfy WTO commitments. Changing from existing amber box payments to those that would likely qualify for inclusion under the blue or green boxes could allow greater market orientation in Taiwan’s rice market, while satisfying food security and farm income support objectives.

An economic evaluation of three ACIAR projects whose primary objective was to improve postharvest grain drying in Thailand and Australia is provided in this report.  During 1983–1996, ACIAR invested A$1.2 million in research designed to improve grain drying in these countries. Based on current adoption, the investment has resulted in a realised net present value of A$3.6 million. A benefit–cost ratio of 3:1 was estimated for the projects. In other words, for each dollar invested, three dollars of project benefits have resulted. A high proportion of realised benefits was estimated to accrue to Australian rice producers, through reduced grain drying costs, while benefits have also been captured by the Thai rice production industry through reduced postharvest...

Rice is a major cash crop in eastern Arkansas, but most rice acres are intensively cultivated and grown on rented land.  No-till is an effective means of sequestering soil carbon and reducing greenhouse gas emissions, and economic incentives exist for no-till in the form of carbon credits.  Studies evaluating the economic potential of carbon credits focus on producers only and do not take into consideration the landlord’s perspective.  This analysis evaluates the profitability and risk efficiency of no-till management and carbon credits in Arkansas rice production from the prospective if the landlord using simulation and stochastic efficiency with respect to a function (SERF).

This study applies portfolio theory to rice varietal selection decisions to find profit maximizing and risk minimizing outcomes. Results based on data from six counties in the Arkansas Delta for the period 1999–2006 suggest that sowing a portfolio of rice varieties could have increased profits from 3 to 26% (depending on the location) for rice producers in the Arkansas Delta. The major implication of this research is that data and statistical tools are available for rice producers to improve the choice of rice varieties to plant each year in specific locations. Specifically, there are large potential gains from combining varieties that are characterized by inverse yield responses to growing conditions such as drought, pest infestation, or the presence of a...

ABSTRACT Pork is the most consumed animal protein around the world. The production levels are significant, which results in the generation of large amounts of slaughter waste. Such waste is often disposed of improperly in agricultural areas, causing environmental imbalance by the contamination of soil and water sources with metals and pathogenic organisms. This study evaluates the phytotoxic effects of pig slaughterhouse waste in natura and after stabilization processes on lettuce (Lactuca sativa Linnaeus, 1753), radish (Raphanus sativus Linnaeus, 1753), and rice (Oryza sativa Linnaeus, 1753), in addition to shoot nutrient contents. To do this, the waste was evaluated through phytotoxicity tests on lettuce, radish, and rice plants in natura (PSWin) as well...

In the last decades, the use of plant growth-promoting rhizobacteria has become an alternative to improve crop production. Rhizobium leguminosarum biovar trifolii is one of the most promising rhizobacteria and is even used with non-legume plants. This study investigated in vitro the occurrence of plant growth-promoting characteristics in several indigenous R. leguminosarum biovar trifolii isolated from soils in the State of Rio Grande do Sul, Brazil. Isolates were obtained at 11 locations and evaluated for indoleacetic acid and siderophore production and inorganic phosphate solubilization. Ten isolates were also molecularly characterized and tested for antagonism against a phytopathogenic fungus and for plant growth promotion of rice seedlings. Of a total...

Development of rice varieties conferring broad-spectrum and durable resistance against brown planthopper (BPH) is one of the major challenges facing the plant breeders. Idea has been generated in this study for incorporating resistance genes of ovicidal response and feeding inhibition into rice breeding lines. Our initial experiments focused on discovering the ovicidal trait in indica rice cultivars. We found that some weedy rice lines had the ovicidal resistance, causing 60% to 100% egg mortality. The egg mortality rate depends on the rice developmental stages and is the highest at the maximum tillering stage. This is the first report of the ovicidal trait in indica rice lines. The BPH resistance in weedy rice lines is not only mediated by the ovicidal...

Cultivated rice (Oryza sativa L.) is self-pollinating, with flowering traits that exclude crosspollination. Hybrid rice seed production is therefore limited by low outcrossing rate between parental lines. To improve outcrossing ability in cultivated rice, common wild rice (O. rufipogon Griff.) was used as a source for outcrossing traits and backcrossed to Suphanburi 1 (SPR1) cultivated rice (BC2). In this study, F5 progenies of the backcross (BC2F5) were grown and evaluated for flowering traits in comparison with SPR1 parent. At flowering, florets were collected to measure the length of anthers and pistil. The anthers of SPR1 averaged 2.32 mm and pistil 1.50 mm, in length. The F5 population ranged 2.40 to 3.93 mm in anther length (3% to 170% of SPR1) and...

Brown planthopper resistant promising line, SPR94007-PTT-27-2-9-3-2, is photoperiod insensitive line derived from single cross of SPR1/IR64 made at Suphan Buri Rice Research Center in 1994. Its F2-F6 progenies had been grown and selected at Pathum Thani Rice Research Center where fixed line, SPR94007-PTT-27-2-9-3, were obtained. In 2008, this line and other breeding lines  were tested for brown planthopper (BPH) resistance and intra-station yield trial. SPR94007-PTT-27-2-9-3 was not selected to be tested in further step due to its unsatisfied yield, but it was only 1 of 2 lines that had no damage of BPH in greenhouse testing. Thus, remained seedlings of those 2 lines had been transplanted in pots and separately harvested panicle by panicle and pedigree...

Root anatomical traits, which include cortical area, aerenchyma area, and xylem features, influence the absorption and translocation of water and nutrients, oxygen transport and the mechanical strength of the root system.  While a number of studies have shown promising functional benefits of anatomical root traits in conferring resource acquisition efficiency, very little is known about the genetic mechanisms underlying natural phenotypic variation of these traits.  In this study, we evaluated 336 Oryza sativa accessions selected from the rice diversity panel for 4 root anatomical traits including, root cross-section area, aerenchyma, and xylem features in well-controlled greenhouse environment.  Considerable phenotypic variation was observed in all root...

Khao Dawk Mali 105 (KDML 105) (Oryza sativa L) is well known as Thai jasmine rice. The major aroma component of KDML 105 is 2-Acetyl-1-pyrroline (2AP). Besides the 2AP, KDML 105 contains various volatile components which contribute aroma and flavor to the rice. Moreover, hydrocarbons, aldehydes, ketones, and alcohols are also found in the rice sample. Due to the complex nature of the sample, some volatile components which co-elute with rice matrix components are not easily identified using traditional GC-MS. GCxGC-TOFMS is a new technique that increases peak capacity and enhances peak sensitivity. The research described here used GCxGC-TOFMS to identify components in the complex mixture of KDML 105 grain sample extracts. Two columns with different...

Development of rice varieties conferring broad-spectrum and durable resistance against brown planthopper (BPH) is one of the major challenges facing the plant breeders. Idea has been generated in this study for incorporating resistance genes of ovicidal response and feeding inhibition into rice breeding lines. Our initial experiments focused on discovering the ovicidal trait in indica rice cultivars. We found that some weedy rice lines had the ovicidal resistance, causing 60% to 100% egg mortality. The egg mortality rate depends on the rice developmental stages and is the highest at the maximum tillering stage. This is the first report of the ovicidal trait in indica rice lines. The BPH resistance in weedy rice lines is not only mediated by the ovicidal...

Brown planthopper (BPH) is a major insect pest of irrigated rice cultivation areas in lower north, central and northeast Thailand. The field experiments were conducted to evaluate the efficacy of nine insecticides to control BPH in farmers’ fields at Suphan Buri, Nakhonayok and Ubon Ratchathani provinces. The results showed that the sulfoxaflor 50 % WG and pymetrozine 50 % WG were the most effective insecticides. The ratios of BPH/mirid bug (MB) in the buprofezin and pymetrozine fields were lower than other fields, which may indicate the less toxicity to MB compared with other insecticides. Moreover, toxicity of each insecticide to MB was investigated using a leaf dipping method and the result indicated that pymetrozine 50 % WG was the lowest toxicity to...

Bacterial leaf blight (BLB) disease is caused by bacteria Xanthomonas oryzae pv. oryzae (Xoo). Infection of this disease can occur at all stages of rice plants from seedling to heading. It can cause as high as 80 % yield reduction. The utilization of resistant varieties have been considered to be the most effective way to control the disease. At present, rice varieties are not widely resistant to BLB disease which has many strains. The resistant varieties having different BLB resistant genes are associated with the different strains of the pathogen. It is necessary to improve rice varieties for widely resistance to BLB disease. Rice improvement for BLB disease resistance was conducted by crossing between a line (RGDU07097-1-MAS-8-9-B-1) with BLB disease...

Blast disease is a major rice disease causing significant rice yield loss worldwide. These are several methods to control this disease, but the most effective and most suitable method is to use blast resistant varieties. Prachin Buri Rice Research Center has released a rice variety ‘Bahng Taen’, which is resistant to blast in the Eastern region. Bahng Taen is a non-glutinous, photoperiod insensitive, early maturity variety with high yielding ability. However, the ability to resist to blast of this variety is declining drastically. It is, therefore, necessary to improve blast resistance in Bahng Taen by introgressing blast resistant genes into its background from two donors; PSL’07F6No.2 and PSL’07F6No.5. These two resistant lines were derived from the...

The development of a water saving rice growing system was stemmed from an attempt to manage efficient water usage, whereby reducing level of water use but still maintaining acceptable level of yield. To be successful in implementing the water saving rice growing system, it is necessary to understand a suitable photosynthetic mechanism and photosynthetic efficiency of each rice cultivar to be grown in such system. An understanding of such knowledge will lead to a better selection of healthy and high yielding cultivars. As such, this study was aimed to compare responses of 10 Thai rice cultivars in terms of photosynthesis rate and growth in well-drained and water-logged systems. Our data indicated that almost all rice cultivars grown under either...

This study reviews the situation of farm mechanization in rice production. Factors affecting labor productivity in rice production, both first and second cropping seasons in 2010/2011, was analyzed using quantile regression and ordinary least square models. The results reveal that increasing farm size would increase labor productivity in both first and second cropping seasons while laborsaving technology would increase labor productivity only in the first cropping season. Thus, increasing farm size, investment in research and development of labor-saving technology, and supporting the appropriate use of labor-saving technology will improve labor productivity in a labor shortage situation.

Sampling accuracy and precision are basic to nematode research and rational management decision. Taylor's Power Law is used to determine sample size. The published power law parameters are used here differently to define levels of reliability associated with a fixed, cost-determined, sample size. Such levels may provide the decision-maker with more informative data on sampling methods and their reliabilities. Instead of solving for unknown sample number, the rearranged equation to solve for sampling accuracy permitted the use of exact Student’s t-values. The t-values for confidence limits and standard normal variate were used. Both statistical techniques resulted in identical confidence band, in terms of being below, at, or above the economic threshold...

ABSTRACT This research aimed to discover the distribution and the primary influence factors of Cu in the soil-rice systems of tropical farmland. Soil samples of farmland and rice plant (stalk and polished rice) from the western region of Hainan Island were collected and studied. The results showed that the average Cu content in the topsoil of the study area was 15.75 mg kg-1; the highest Cu content (45.92 mg kg-1) was found in the rice fields of the northern area, where pyroclastic parent material is distributed. Thus, there is a potential for Cu contamination of the rice grown in this region. The average contents of Cu in the rice stalks and polished rice were 16.9 and 5.68 mg kg-1, respectively, indicating that the stalks had a larger capacity for Cu...

Inheritance of blast resistance in rice to two Pyricularia grisea races, IB-1 and IB-9
Provedor de dados: 54
Autores: Filippi,Marta C. de; Prabhu,A.S.
Seven sources of resistance to the two predominant races IB-1 and IB-9 of the rice blast pathogen Pyricularia grisea were selected based on leaf blast reaction in tests conducted under controlled greenhouse conditions. Crosses involving resistant and susceptible parents were made to study the inheritance of the disease reaction for different sources of resistance. The F1 and F2 progenies of all crosses, including backcrosses to resistant and susceptible parents, were tested for reaction to leaf blast. The data showed that resistance is controlled by one to three genes that segregate independently in most of the donors. Non-allelic interaction among resistance genes, including dominant epistasis, was identified.

Autores: Sempere,F.; Santamarina,M.P.
The aim of this research was the analysis of the possible antagonistic effect of Penicillium oxalicum over the pathogen rice fungus A. alternata under different conditions of temperature, water activity and culture media. The macroscopic study of the dual growth revealed that according to the Index of Dominance P. oxalicum was more competitive that A. alternata at 25ºC whereas at 15ºC was this species. Microscopic analysis showed that P. oxalicum was a mycoparasite of A. alternata at all conditions tested. The antagonist penetrated into A. alternata and disintegrated its conidiophores and conidia. The results suggests that P. oxalicum may be a possible biological control agent of the rice pathogens in a future.
