ANTAGONISM IS THE PREDOMINANT EFFECT OF HERBICIDE MIXTURES USED FOR IMIDAZOLINONE-RESISTANT BARNYARDGRASS (Echinochloa crus-galli) CONTROL Planta Daninha
MATZENBACHER,F. O.; KALSING,A.; DALAZEN,G.; MARKUS,C.; MEROTTO JR,A..
ABSTRACTHerbicides mixtures are used in many situations without the adequate knowledge related with the effect on major target weeds. The objective of this study was to evaluate the effects of different herbicides mixtures used in irrigated rice in order to establish the adequate combinations for the prevention and management of herbicide resistance in barnyardgrass (Echinochloa crus-galli). Three experiments were performed at field conditions with all major post-emergent herbicides used in irrigated rice in Brazil. The first experiment was performed with barnyardgrass resistant to imidazolinone herbicides and herbicides applied at label rates. The second and third experiments were performed with barnyardgrass resistant and susceptible to imidazolinone...

Comportamento de cultivares de arroz irrigado sob regime de sequeiro favorecido, em Rio Branco-Acre. Infoteca-e
CAMPOS, I. S.; MEDEIROS, J. A..
As cultivares atualmente plantadas na região apresentam porte alto, principalmente quando cultivadas em áreas de matas recém desbravadas e espaçamento reduzido, o que favorece o acamamento. um dos principais problemas da orizicultura acreana. Os trabalhos de introdução de material genético para as condições do Estado do Acre, não tem apresentado resultados satisfatórios, possivelmente, pelo fato desse material ter sido desenvolvido em região de clima, solo e cultivo, diferentes das condições desse Estado. Partindo de 30 cultivares provenientes do Centro de Pesquisa Agropecuária do Trópico Úmido (CPATU), foi conduzido um ensaio no campo experimental da EMBRAPA/UEPAE-Rio Branco, no ano agrícola 19801/81, em área de terra firme, de Latossolo Amarelo, textura...

ABSTRACT Tricyclazole is currently one of the fungicides recommended for the treatment of diseases in irrigated rice. However, there is relatively little information on its cytotoxic and genotoxic potential. The objective of this study was to evaluate the cytotoxicity and genotoxicity of rice crop water after apllication of the tricyclazole fungicide through the Allium cepa L. test. The rice crop water samplings were collected before and 1, 15 and 30 days after application of the fungicide in rice plant shoots. The Allium cepa roots were placed in contact with the rice crop water to check for possible chromosomal abnormalities and mitotic index of the bioindicators meristematic cells. The data obtained by the Allium cepa test indicates that the application...

Effect of Nitrogen Rates and Split Nitrogen Fertilization on Grain Yield and its Components in Flooded Rice Chilean J. Agric. Res.
Hirzel,Juan; Pedreros,Alberto; Cordero,Karla.
Nutritional management in rice (Oryza sativa L.) crops is mainly associated with N fertilization, which is difficult to adjust in field conditions due to variations in soil type and climatic conditions. Between 28 000 and 46 000 ha per year is dedicated to rice production in Chile and profits depend on fertilization. A field experiment determine the effect of N rates and split N fertilization on grain yield and its components was carried out in two locations during two consecutive seasons (2007 to 2009), where five N rates and five split N fertilizations were evaluated. The locations were in Parral (36º2’ S; 72º08’ W, Vertisol) and San Carlos (36º19’ S; 71º59’ W, Inceptisol), with N rates of 80, 100, 120, 140, and 160 kg ha-1 applied in different...

Evaluation of the ORYZA2000 Rice Growth Model under Nitrogen-Limited Conditions in an Irrigated Mediterranean Environment Chilean J. Agric. Res.
Artacho,Pamela; Meza,Francisco; Alcalde,José Antonio.
ORYZA2000 is a growth model for tropical lowland rice ( Oryza sativa L.) developed by the International Rice Research Institute and Wageningen University. This model has been evaluated extensively in a wide range of environments. However, reports examining japonica cultivars growing in temperate climates are scarce. In this study, ORYZA2000 was calibrated and evaluated using data from experiments carried out in the South-Central area of Chile. These experiments were performed on a japonica rice cultivar growing under an irrigated Mediterranean environment at various N rates. ORYZA2000 was then applied to explore potential yield and grain yield response to N fertilization under likely weather conditions in the major rice-producing area in Chile. ORYZA2000...

IDENTIFICATION OF SUITABLE AREAS FOR IRRIGATED RICE CROPPING USING MODIS IMAGES AND HAND MODEL REA
MENGUE,VAGNER P.; FONTANA,DENISE C..
ABSTRACT One of the most relevant activities of Brazilian economy is agriculture. Among the main crops in Brazil, rice is one of high relevance. The state of Rio Grande do Sul, in Southern Brazil, is responsible for 68.7% of domestic production (IBGE, 2013). The goal of this study was to develop a low-cost methodology with a regional scope to identify suitable areas for irrigated rice cropping in this state, using spectro-temporal behavior of vegetation index by means of MODIS images and HAND model. The rice-cropped area of this study was the southern half of the State. Using the HAND model, flood areas were mapped to identify irrigated rice cultivation. We used multi-temporal images of vegetation index from MODIS sensor, covering the period from August...

Faria,Lessandro Coll; Beskow,Samuel; Colombo,Alberto; Nörenberg,Bernardo Gomes; Rettore Neto,Osvaldo; Simões,Matheus Chagas.
ABSTRACT: Investigations demonstrate that the wind is the factor that causes the biggest negative influence on water application of sprinkler irrigation systems. Therefore, this paper aims to evaluate, in in-field conditions, the influence of wind on the water distribution uniformity of a mechanical lateral move sprinkler system used for irrigation in rice crop in the South of Rio Grande do Sul State, Brazil. The equipment is located at the Campo Experimental de Terras Baixas (ETB) of EMBRAPA/CPACT and operates with water emitters model I-Wob installed in drop tubes in a distance of 2.8m above the soil surface, having a uniform space of 2.3m between each other and pressure regulators of 68.9kPa. Sixteen in-field evaluations were done and they permitted to...

Methane emission induced by short-chain organic acids in lowland soil Rev. Bras. Ciênc. Solo
Moscôso,Janielly Silva Costa; Silva,Leandro Souza da; Pujol,Stefen Barbosa; Giacomini,Sandro José; Severo,Fabiane Figueiredo; Marzari,Laura Brondani; Molin,Gustavo Dal.
ABSTRACT Methane (CH4) is the second major greenhouse gas after CO2, exerting a significant influence on the climate and the chemistry of the atmosphere. In lowland soil, acetate and H2/CO2 are the most important precursors of CH4 and formed from organic matter fermentation in an anaerobic environment, giving rise to short-chain organic acids (ethanoic, propanoic, and butanoic), depending on the type of crop residue and the soil management system. Ethanoic acid can be directly converted to CH4 by methanogenic microorganisms, but propanoic and butanoic acids must be converted to acetate before being converted to CH4. This study aimed to quantify, in isolation, the dynamics and CH4 emission potential of the three short-chain organic acids found in flooded...
