QTL mapping for physiology, yield and plant architecture traits in cotton (Gossypium hirsutum L.) grown under well-watered versus water-stress conditions
Provedor de dados: 69

Increasing scarcity of irrigation water is a major threat to sustainable production of cotton (Gossypium hirsutum L.). Identifying genomic regions contributing to abiotic stress tolerance will help develop cotton cultivars suitable for water-limited regions through molecular marker-assisted breeding. A molecular mapping F2 population was derived from an intraspecific cross of the drought sensitive G. hirsutum cv. FH-901 and drought tolerant G. hirsutum cv. RH-510. Field data were recorded on physiological traits (osmotic potential and osmotic adjustment); yield and its component traits (seedcotton yield, number of bolls/plant and boll weight); and plant architecture traits (plant height and number of nodes per plant) for F2, F2:3 and F2:4 generations under...

Cotton genetic diversity study by AFLP markers
Provedor de dados: 69
Autores: Murtaza,Naveed.
Amplified fragmentlength polymorphism (AFLP) markers have been used to ascertain the intensity of inherent diversity and relatedness in cotton (Gossypium spp.) plants. The effectiveness of this method to distinguish inter and intra specific difference in cotton could be handy in cultivar recognition and in marker assisted parental selection tool for plant breeders. Twenty cotton cultivars belonging to Gossypium hirsutum L., and G. arborium L. from the Pakistan and US origin were used for AFLP based genetic diversity estimates. The objective of this study was to assess the level of genetic variation among some cotton cultivars belonging to the old and new world species of cotton. Four EcoRI-MseI primer-pair combinations were used forthe AFLP analysis. The...

Environmental interaction, additive and non-additive genetic variability is involved in the expression of tissue and whole-plant heat tolerance in upland cotton (Gossypium hirsutum. L)
Provedor de dados: 74
Autores: Hafeez-ur-Rahman,.
Heat tolerance is measured at tissue level by cellular membrane thermostability (CMT) and at the whole plant level by the heat tolerance index (HTI). Eight upland cotton cultivars and 15 crosses were used to determine the type and extent of genetic variability associated with the expression of these traits between and within environments. Heat stress and non-stress conditions were used as the CMT environments and years for HTI. The wide variation in heterotic expression and combining ability effects observed for CMT and HTI suggest multigenic inheritance of these traits. Significant genetic variability across environments was evident but the traits were not highly heritable because of substantial environmental interaction. The available genetic variability...

Controle de qualidade na produção massal de Trichogramma pretiosum, 1879 (Hymenoptera: Trichogramatidae).
Provedor de dados: 14
Autores: ALMEIDA, R. P. de.
O controle biológico de insetos-praga se constitui em uma das táticas mais importante do manejo integrado de pragas, visto que, além de poder ser utilizado em consonância com todos os demais métodos de controle, é ambientalmente seguro e sem risco para saúde humana. Sua eficiência, em condições naturais, nem sempre é alcançada devido as baixas taxas de ocorrência, quando comparada às pragas. Por isso, na maioria das situações, necessário se faz utilizar inimigos naturais produzidos de forma artificial, em biofábricas, possibilitando sua liberação em grandes áreas de cultivo do algodoeiro. Um dos gêneros de parasitoide mais utilizados no mundo como agente de controle biológico é denominado de Trichogramma (Hymenoptera: Trichogrammatidae). Sua aplicação é...

O solo é considerado elemento básico no que diz respeito a qualquer atividade agropecuária, sendo imprescindível o emprego de técnicas visando à melhoria de sua fertilidade e conservação de forma a torná-lo cada vez mais produtivo com sustentabilidade. Nos ambientes semiáridos, os solos tendem a ser mais susceptíveis a erosão, e o uso de práticas de manejo inadequadas, como queimadas, preparo do solo com grade aradora e plantio morro abaixo, vem piorando a situação. Uma das alternativas para sanar esse processo é o uso de sistemas agroecológicos, os quais buscam imitar os ecossistemas naturais, comumente considerados sustentáveis (Figura 1). No entanto, alguns aspectos em relação a manejo de água e solo carecem de informações. Para isso, elaborou-se esta...

No Cerrado brasileiro, o algodoeiro é cultivado em uma grande diversidade de condições edafoclimáticas com diferentes pressões de fatores bióticos, principalmente o ataque de pragas e doenças, além de diferentes épocas de plantio, o que torna de suma importância o ciclo da cultura. Nos últimos anos, a área de produção tem avançado na região do MATOPIBA, e a avaliação de materiais adaptados para esta condição de cultivo é também de grande relevância. Atualmente, o maior problema da cultura do algodão no Cerrado é o custo de produção, e desta forma, para semanter competitivo no mercado internacional, a produção de fibra de qualidade, com elevada produtividade, torna-se fundamental. A incidência de doenças como a ramulária e mancha-alvo, além dos nematoides,...

Cátions trocáveis e controle da acidez em latossolo argiloso sob sistemas de manejo e de produção de algodão, milho e soja.
Provedor de dados: 14
Autores: FERREIRA, A. C. de B.; BORIN, A. L. D. C.; LAMAS, F. M.; FERREIRA, G. B.; RESENDE, A. V. de.
O Cerrado brasileiro, em geral, são naturalmente ácidos e intemperizados, apresentando níveis tóxicos de alumínio (Al3+), baixos níveis de saturação por bases trocáveis, baixa capacidade de troca de cátions (CTC) e reduzidos teores de matéria orgânica, além de reduzida disponibilidade de nutrientes, com exceção de ferro e manganês (Lopes; Guilherme, 2016). Não obstante essas características, são solos profundos, com condições favoráveis à mecanização e respondem às correções químicas, viabilizando a produção agrícola rentável. A região do Cerrado contribui em grande proporção para a produção nacional de soja, de milho e de quase todo algodão (98%) produzido no País (Conab, 2021). Mas, para que isso acontecesse, os solos precisaram ser corrigidos...

Por que é tão importante preservar os inimigos naturais e privilegiar a seletividade de inseticidas nas aplicações dentro do manejo integrado de pragas na cultura do algodoeiro.
Provedor de dados: 14
Autores: ALMEIDA, R. P. de; SILVA, C. A. D. da.
Os agentes de controle biológico ou inimigos naturais (predadores, parasitoides e entomopatógenos) são capazes de reduzir populações de artrópodes-praga a níveis inferiores aos de dano econômico, mas sem ocasionar efeitos colaterais indesejáveis ao meio ambiente. Podem ser manejados de forma conservativa, em agroecosistemas estáveis ou criados em laboratórios (biofábricas), para serem liberados, periodicamente, em grandes quantidades em lavouras comerciais (cultivos perenes ou anuais). Defensivos, principalmente os de largo espectro (não seletivos aos inimigos naturais), são a principal tática para o controle de insetos-praga, porém podem causar efeitos deletérios aos inimigos naturais. O problema é potencializado quando empregados sem critérios técnicos,...

Autores: SEVERINO, L. S.; SCHLICK, G. D. de S.; DE PAULA, M. P.; SANTOS, T. I. dos; SOUZA, E. C. S.
O óleo de mamona (Ricinus communis) tem grande demanda na indústria química mundial para ser utilizado em diversos produtos. Essa cultura é atraente para várias regiões do Brasil, principalmente por sua característica de boa tolerância à seca no cultivo em segunda safra e pelo seu efeito supressor de algumas espécies de nematoides que causam redução de produtividade em outras lavouras agrícolas. Os avanços na tecnologia de produção de mamona estão possibilitando sua expansão para novas regiões de cultivo. A mamona é principalmente uma opção para rotação de culturas no sistema soja-milho-algodão e para cultivo sob irrigação. A obtenção de altas produtividades na cultura da mamona depende da adequada nutrição da planta. O estudo da marcha de absorção e...

Plantas de cobertura (PC) são fundamentais para a produção de palhada e cobertura do solo no sistema plantio direto (SPD). Entretanto, existem poucas informações do potencial de produção de matéria seca (MS) e do acúmulo de nutrientes por PC no Cerrado brasileiro, quando cultivadas na entressafra, em sucessão à soja e antecedendo ao algodoeiro. Objetivou-se nesse estudo avaliar a produtividade de MS, o acúmulo de nutrientes por PC e seus efeitos sobre a produtividade do algodoeiro. Um experimento foi conduzido no estado de Goiás, Brasil, sendo repetido durante três anos, e constou de 7 tratamentos com PC em cultivos solteiros ou consorciados: Panicum maximum Aruana, Urochloa brizantha cv BRS Piatã, Urochloa ruziziensis, Pennisetum glaucum, Sorghum bicolor...

Em todos os tipos de sistemas produtivos, quer sejam monocultivo ou policultivo, irrigado ou de sequeiro, agroecológico ou onvencional, grande parte das limitações da produção está vinculada a ocorrência de pragas. Os diferentes cultivos de importância econômica (commodities ou não), que visam a sustentabilidade da produção agrícola, têm por princípio direcionar suas ações para o manejo das pragas com base em princípios ecológicos. Os sistemas agroecológicos, por sua vez, têm por objetivo a otimização da produção de forma a garantir a sustentabilidade do agroecossistema, conferindo qualidade e segurança ambiental. As técnicas de produção não precisam necessariamente ser as mais sofisticadas, entretanto devem atender às necessidades das práticas de cultivo...

Autores: MORAIS, J. P. S.; FARIAS, F. J. C.; BELOT, J-L.; MARTINS, R. S. A.; MIZOGUCHI, E. T.
Produtos vegetais possuem variabilidade natural. A indústria transforma essas commodities em um bem industrial com menor variabilidade. Assim, fibras de algodão são transformadas pela indústria têxtil em fios com diferentes características para a produção de malhas e tecidos. Para cada produto, a indústria demanda fibras com características específicas. Muitas vezes, não importa a qualidade do material inicial, mas sim a exatidão e precisão quanto aos parâmetros do material. Ou seja, se o maquinário vai produzir um determinado tipo de fio, a indústria não pode receber fibras mais longas ou mais curtas do que o planejado. A classificação dos parâmetros da fibra de algodão é desafiadora pelo grande número de parâmetros que podem impactar a qualidade do fio....

The boll weevil causes serious damage to the cotton crop in South America. Several studies have been published on this pest, but its phenology and behavior under the tropical conditions prevailing in Brazil are not well-known. In this study the feeding behavior and main food sources of adult boll weevils throughout the year in Central Brazil was investigated. The digestive tract contents of insects captured in pheromone traps in two cotton fields and two areas of native vegetation (gallery forest and cerrado sensu stricto) were analyzed. The insect was captured all through the year only in the cerrado. It fed on pollen of 19 different plant families, on Pteridophyta and fungi spores and algae cysts. Simpson Index test showed that the cerrado provided...

In situ and genetic characterization of Gossypium barbadense populations from the states of Pará and Amapá, Brazil
Provedor de dados: 86
Autores: Almeida,Vanessa Cavalcante de; Hoffmann,Lúcia Vieira; Yokomizo,Gilberto Ken It; Costa,Joaquim Nunes da; Giband,Marc; Barroso,Paulo Augusto Vianna.
The objective of this work was to characterize the populations of Gossypium barbadense in the states of Amapá and Pará, Brazil. In situ characterization was conducted through interviews with the owners of the plants and environmental observations. Leaf or petal tissue as well as seed samples were collected for genetic characterization by single sequence repeats markers and for storage in germplasm banks, respectively. The plants were maintained in dooryards and used mainly for medical purposes. The genetic analysis showed no heterozygous plants at the loci tested (f = 1), indicating that reproduction occurs mainly through selfing.

The effect of cover crop and crop rotation on soil water storage and on sorghum yield
Provedor de dados: 86
Autores: Azevedo,Demóstenes Marcos Pedrosa de; Landivar,Juan; Vieira,Robson Macedo; Moseley,Daryl.
Crop rotation and cover crop can be important means for enhancing crop yield in rainfed areas such as the lower Coastal Bend Region of Texas, USA. A trial was conducted in 1995 as part of a long-term cropping experiment (7 years) to investigate the effect of oat (Avena sativa L.) cover and rotation on soil water storage and yield of sorghum (Sorghum bicolor L.). The trial design was a RCB in a split-plot arrangement with four replicates. Rotation sequences were the main plots and oat cover crop the subplots. Cover crop reduced sorghum grain yield. This effect was attributed to a reduced concentration of available soil N and less soil water storage under this treatment. By delaying cover termination, the residue with a high C/N acted as an N sink through...

John R. Commons and the Evolution of Institutions: The Case of the Malian Cotton Sector
Provedor de dados: 31
Autores: Theriault,   Veronique; Sterns,   James A.
Applying John R. Commons institutional economic framework, this paper analyzes the evolution of the key institutions in the Malian cotton sector starting with the CFDT contract following the country‘s Independence in 1960; the nationalization of the cotton gin company, CMDT, in 1974; the completion of a vertically integrated market structure from the mid-1980s to mid-1990s; and, finally, to the current state of the market-oriented reforms in 2010. In accordance with John R. Commons’ economic theory, institutional changes in the Malian cotton sector have led to both intended and unintended consequences impacting economic performance at the farm, gin, and State levels, which in turn, has contributed to the emergence of new limiting factors. At present, the...

Estimating productivity of water at different spatial scales using simulation modeling
Provedor de dados: 31
Autores: Droogers,   Peter; Kite,   Geoff.
A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

Costs differ among variable rate application systems.  Most feasible in Tennessee are the 1-bin and 2-bin spreader beds mounted to existing chassis with an owner-added variable rate controller and global positioning system.  Truck spreader systems required more acreage or larger custom charges making it difficult to breakeven and earn a profit.

Autores: Kendy,   Eloise; Molden,   David J.; Steenhuis,   Tammo S.; Liu,   Changming; Wang,   Jinxia.
The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 2000. To systematically address these relationships, we use a comprehensive water-balance approach. Our results indicate that a single, longstanding policy-that of using groundwater to meet the crop-water requirements not supplied by precipitation-is responsible for the steady rate of groundwater decline.

Cotton in Zambia: 2007 Assessment of its Organization, Performance, Current Policy Initiatives, and Challenges for the Future
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is one unquestioned success of Zambia’s turn towards a market economy. After liberalization in late 1994, production rose from 20,000 mt to over 100,000 mt in the 1998 harvest year. After collapsing to less than 50,000 mt in 2000, it has risen steadily, nearing 200,000 mt in 2005. Over 2002-2005, exports of cotton lint were first among all agricultural exports in value, 30% higher than any other agricultural export (Export Board of Zambia 2006). The closest competitor to cotton during this time –raw cane sugar –is primarily produced on large operations, while cotton is almost entirely a smallholder crop. Its potential role in poverty alleviation and food security is, thus, very large. The success of this sector has been achieved despite persistent...

Measuring Competition for Textiles: Does the United States Make the Grade?
Provedor de dados: 31
Autores: Welch,   J. Mark; Lyford,   Conrad P.
Increasing competition from foreign manufacturers threatens the viability of textile producers in the United States. This paper evaluates the U.S. competitive position in the cotton yarn segment using established quantifiable measures and provides an overall competitive assessment. The measures employed show the United States to be at a relative competitive disadvantage when compared to major international producers of cotton yarn. However, the margin of this competitive disadvantage is shown to be relatively small and in some cases, decreasing.

The objective of this article is to propose the use of moment functions and maximum entropy techniques as a flexible way to estimate conditional crop yield distributions. We present a moment based model that extends previous approaches in several dimensions, and can be easily estimated using standard econometric estimators. Upon identification of the yield moments under a variety of climate and irrigation regimes, we utilize maximum entropy techniques to analyze the distributional impacts from switching regimes. We consider the case of Arkansas, Mississippi, and Texas upland cotton to demonstrate how climate and irrigation affect the shape of the yield distribution, and compare our findings to other moment based approaches. We empirically illustrate...

Cotton Futures Dynamics: Structural Change, Index Traders and the Returns to Storage
Provedor de dados: 31
Autores: Power,   Gabriel J.; Robinson,   John R.C.
The commodity bull cycle of 2006-2008 and subsequent dramatic price decline have been a source of hardship for traditional commodity market participants such as producers and merchant/shippers. The usefulness of futures markets has been called into question, especially given that some market movements did not appear to be justified by economic fundamentals. An emerging research literature examines the possible influence of futures traders, and particularly the non-traditional Index Traders, on the well-functioning of futures markets and underlying commodity markets. Cotton is a relatively under-studied commodity that is of particular importance for producers in the South and Southwest. To this end, this paper asks the following questions: (1) What role...

Competition between the U.S. and West Africa in International Cotton Trade: A Focus on Import Demand in China
Provedor de dados: 31
Autores: Muhammad,   Andrew; McPhail,   Lihong Lu; Kiawu,   James.
We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that African cotton producers are ill affected by U.S. cotton subsidies, our focus is the price competition between the C4 countries (Benin, Burkina Faso, Chad and Mali) and United States in China. Demand estimates are used to project how U.S. prices affect China’s imports by country. In comparing demand projections, results show that the relationship between the United States and the C4 has more to do with how U.S. prices can affect global prices rather than any substitute or competitive relationship in the Chinese market.

The textile industry of Kazakhstan is presented basically by enterprises created in period of centrally planned economy and as consequence. Low labor productivity, lacking equipment base and technologies, poor marketing are problems of the current state of industry.   But, there are also advantages as a vicinity of potential cotton manufacturers - Uzbekistan, Tajikistan, Turkmenistan.  A free economic zone (FEZ) “Ontustik” has been established and a program of “Ontustik” FEZ development has been adopted for developing the cotton and textile cluster in Kazakhstan. The law “About development of the cotton branch” has been adopted in Kazakhstan to provide the textile enterprises with necessary raw material and to develop the domestic cotton growing.

INCOME DISTRIBUTIONAL IMPACTS OF TRADE POLICIES IN A MULTI-MARKET FRAMEWORK: A CASE IN PAKISTAN
Provedor de dados: 31
Autores: Hudson,   Darren; Ethridge,   Don E.
The impacts of using export taxes as a price control in a multi-market framework are explored using the cotton and yarn sectors in Pakistan as examples. Results show that the export tax on cotton increased domestic consumption and decreased exports of cotton in Pakistan, transferring income from cotton producers to yarn spinners and the government. There was a social loss to Pakistan in the cotton sector. The export tax on cotton increased domestic yarn production, consumption, exports, and incomes of yarn spinners, but resulted in a large transfer (social loss) out of the yarn sector.

Modeling Texas Dryland Cotton Yields, With Application to Crop Insurance Actuarial Rating
Provedor de dados: 31
Autores: Chen,   Shu-Ling; Miranda,   Mario J.
Texas dryland upland cotton yields have historically exhibited greater variation and more distributional irregularities than the yields of other crops, raising concerns that conventional parametric distribution models may generate biased or otherwise inaccurate crop insurance premium rate estimates. Here, we formulate and estimate regime-switching models for Texas dryland cotton yields in which the distribution of yield is conditioned on local drought conditions. Our results indicate that drought-conditioned regime-switching models provide a better fit to Texas county-level dryland cotton yields than conventional parametric distribution models. They do not, however, generate significantly different Group Risk Plan crop insurance premium rate estimates.

Environmental Benefits from Reduced Pesticide Use and Returns to Research: An Application to the U.S. Cotton Industry
Provedor de dados: 31
Autores: Sande,   Doris N.; Mullen,   Jeffrey D.; Matekole,   Augustus N.
Cotton production is one of the main pesticide use industries in the U.S. This intensive use has resulted in the disruption of naturally occurring biological control factors that regulate other insect pest populations and “the pesticide treadmill”. The result is resistance to insecticides, high control costs and unacceptable levels of chemical insecticides in the environment. Concerns about the environmental and human health effects from pesticide use thus need to be modeled in evaluation studies.

By using a stochastic frontier framework, the mutual effect of input use on production risk and inefficiency is investigated. Disentangling this mutual effect proves important for empirical reasons, at least when applied to west Tennessee cotton systems grown after various cover crops. The most striking result is that the stochastic frontier model, when compared with a typical Just-Pope model, reorders the relative riskiness of cover-crop regimes associated with the cotton systems.

1. Changes in spinning technology have increased the premium on high quality lint in the world market and increased the discount for lint contaminated with non-vegetative matter 2. The inherent characteristics of most African lint, plus the fact that it is hand-picked, should give it a substantial premium in the world market. However, because so much African lint is highly contaminated by world standards, much of it trades at a discount to Index A. 3. Zambia has been the outstanding success among a sample of nine SSA countries in improving quality; this achievement is directly attributable to the efforts of Dunavant and Cargill, made possible by company culture and by the concentrated structure of Zambia's industry 4.

Autores: Meeks,   Timothy A.; Flanders,   Archie; Shurley,   W. Donald; White,   Fred C.; Gunter,   Lewell F.
Harvest timeliness is a continual problem in rotation of cotton and peanuts.  Efficient allocation of land and labor resources during production of cotton and peanuts requires decisions be made on allocating resources throughout the growing season. Of particular concern is efficient allocation during planting and harvesting.  Through economic analysis and linear programming optimization, planting and harvesting timeliness issues are addressed and compared with prevailing practices.  Results for a representative farm indicate that cotton planting should increase during the early period of the planting season as compared with current practice, and most cotton should be harvested before peanut harvest begins.

This study examined adoption of ten best management practices (BMPs) to control weed resistance to herbicides. Using data from a survey of 1,205 U.S. cotton, corn, and soybean growers, count data models were estimated to explain the total number of practices frequently adopted. Ordered probit regressions were used to explain the frequency of individual BMP adoption. Growers practicing a greater number of BMPs frequently (a) had more education, but less farming experience; (b) grew cotton, (c) expected higher yields relative to the county average; and (d) farmed in counties with a lower coefficient of variation (CV) for yield of their primary crop. Yield expectations and variability were significant predictors of the frequency of adoption of individual...

Is Investment in Agricultural Research a Good Substitute for Price Support in U.S. Cotton?
Provedor de dados: 31
Autores: Pan,   Suwen; Wang,   Changgang; Hudson,   Darren.
This article examines the effects of R&amp;D on cotton yield and relationship between R&amp;D and commodity support programs. The results indicate that yield elasticities with respect to cotton R&amp;D is around 0.2-0.5 based on different regions. It further indicates that R&amp;D increases government expenditures when both commodity programs and R&amp;D funding exist. However, if the future WTO Doha negotiations rules out the possibility of price support programs, increasing R&amp;D funding may provide one of the solutions for farmers to recover their income with 5-6 years lag.

Industry Organization and Output Size Distribution of Cotton Gins in the U.S.
Provedor de dados: 31
Autores: Mutuc,   Maria Erlinda M.; Hudson,   Darren.
With cotton output declining by 46 percent from 2005-2008 (from 23.89 M bales in 2005 to 12.8 M bales in 2008), gins are processing less cotton.  This paper examines how output size distribution of cotton gins in the U.S. has evolved and the extent to which the developments in the U.S. ethanol industry, specifically the passage of the Energy Policy Act in 2005 (and its subsequent revisions), have influenced this structural process.  Markov transitional probability matrices (TPMs) are estimated for two periods: 1994-2004 and 2005-2008 to determine changes in output size distribution of gins.  TPMs indicate that relative to the pre-2005 period, gins had a greater propensity to process lower outputs after 2005. It is purported that in industries constrained...

Prices Paid to Cotton Farmers: How Does Zambia Compare to its African Neighbors?
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
1. Zambia has paid among the best nominal seed cotton prices to farmers in SSA since 1995.  2. By a more refined measure (share of FOT), during 1995-1999, Zambia paid prices comparable to those in Tanzania (a very competitive sector), and substantially higher than in Mozambique and WCA. However, from 2000-2005, Zambia's pricing performance fell, and exceeded only Zimbabwe and Mozambique in our sample  3. The recently announced reference price for 2008 of ZKW 1,200/kg of seed cotton was negotiated and jointly announced by ginners and farmers. It amounts to about 53% of FOT at current exchange rates and Index A prices; about equal to recent shares received by farmers in Zambia, but well below levels in WCA and Tanzania.  4. What “rules of the game” are...

The Role of Institutional Environments on Technical Efficiency: A Comparative Stochastic Frontier Analysis of Cotton Farmers in Benin, Burkina Faso, and Mali
Provedor de dados: 31
Autores: Theriault,   Veronique.
This paper examines the role of institutional environments on cotton farmer technical efficiency scores in Benin, Burkina Faso, and Mali using a stochastic frontier production approach. First, the key institutional changes that have occurred with the recent market-oriented reforms are discussed. Then, farm efficiency per country is measured using cross-sectional data collected by the Cotton Sector Reform Project of the Africa, Power, and Politics Programme in 2009. Results from a one-stage estimation procedure suggest that while no technical inefficiency exists in Benin, an average technical efficiency of 69% and 46% is found in Burkina Faso and Mali, respectively. Agricultural development policies focusing on reducing the inefficiency at the farm level in...

Evaluating Crop and Revenue Insurance Products as Risk Management Tools for Texas Cotton Producers
Provedor de dados: 31
Autores: Field,   James E.; Misra,   Sukant K.; Ramirez,   Octavio A.
This paper develops and illustrates the application of a procedure to evaluate and compare the cost effectiveness of alternative crop insurance products for cotton in terms of their effect on expected producer net returns and the variation of net returns.  Farm unit-level cotton yields and state-level price distributions are estimated by a multivariate nonnormal parametric modeling procedure and used to simulate the net returns to alternative crop insurance products over a 10-year planning horizon.  The ranking of alternative insurance products using third-degree stochastic dominance is presented for Texas cotton producers.

Reconciling Theoretical Hedging Models with the Experience of Cotton Merchants in March 2008
Provedor de dados: 31
Autores: Janzen,   Joseph P.
Analysis of the cotton futures price spike and its effects on commercial hedgers suggest that we do not completely understand the behavior of markets and firms in periods of extreme volatility. After presenting the story of the cotton futures price spike, this paper argues that explanations related to the funding liquidity of firms and the liquidity of the markets themselves may help us better understand market volatility. A simple model of futures market equilibrium in the presence of liquidity constraints demonstrates how prices can spike as fast as they did and why such spikes can drive firms to exit.

Urgent Need for Effective Public-Private Coordination in Zambia’s Cotton Sector. Deliberations on the Cotton Act.
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is an unquestioned success of Zambia’s turn towards a market economy. Yet the entry over the past two years of new players has put the sector under great stress and may have pushed it to a turning point. Now more than ever, effective “rules of the game” are urgently needed to protect Zambia’s remarkable cotton success story. Other countries in southern and eastern Africa have seen dramatic declines in input credit and extension to farmers, and in cotton quality, when competition among ginning firms intensified in the absence of suitable rules of the game. The focus in Zambia must be on establishing broadly accepted rules of the game that ensure honest competition that does not undermine input credit, extension, and cotton quality.

The “cotton issue” has been a topic of several academic discussions for trade policy analysts. However the design of trade and agricultural policy in the EU and the USA has become a politically sensitive matter throughout the last five years. This study utilizing the Agricultural Trade Policy Simulation Model (ATPSM) aims to gain insights into the global cotton market, to explain why domestic support for cotton has become an issue, to quantify the impact of the new EU agricultural policy on the cotton sector, and to measure the effect of eliminating support policies on production and trade. Results indicate that full trade liberalization would lead the four West African countries to better terms of trade with the EU. If tariff reduction follows the...

Do U.S. Cotton Subsidies Affect Competing Exporters? An Analysis of Import Demand in China
Provedor de dados: 31
Autores: Muhammad,   Andrew; McPhail,   Lihong Lu; Kiawu,   James.
We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that developing countries are negatively affected by U.S. cotton subsidies, our focus is the price competition between the United States and competing exporters (Benin, Burkina Faso, Chad, Mali, India, and Uzbekistan). We further project how U.S. programs affect China’s imports by country. Results indicate that if U.S. subsidies make other exporting countries worse off, this effect is lessened when global prices respond accordingly. If subsidies are eliminated, China’s cotton imports may not fully recover from the temporary spike in global prices.

U.S. Agricultural Export Credits after the WTO Cotton Ruling: The Law of Unintended Consequences
Provedor de dados: 31
Autores: Benitah,   Marc.
The recent WTO cotton ruling has led to a paradoxical result for the United States, a result that seems a textbook illustration of the "law of unintended consequences". Indeed, during the Uruguay Round negotiations of the present WTO agreements, the United States refused to put agricultural export credits in the category of agricultural export subsidies, where they would then have been subject only to reduction commitments. Paradoxically, the United States finds itself now in a position where these same agricultural export credits that it did not condescend to reduce during the Uruguay Round are openly considered as prohibited export subsidies. This article analyses and criticizes the tortuous legal path followed by the cotton panel before arriving at such...

Autores: Hudson,   Darren.
The World Trade Organization (WTO) negotiations could have important implications for Southern Agriculture.  This paper explores some of the issues surrounding the WTO negotiations for cotton.  Specifically, this paper examines the impacts of the phase-out of the Multi-Fiber Arrangement (MFA) on the location of textile production and cotton trade flows. Generally, it is believed that the WTO negotiations will have little direct impact on cotton, but will have indirect impacts through textile policy.

The purpose of this paper is to assess the opportunity returns forgone to cotton producers in the lower Mid-South region of the United States for growing cotton, compared to alternative commodities. We calculate the actual net returns per acre for selected cotton-producing counties in Arkansas, Louisiana, and Mississippi. In addition, we calculate the opportunity returns per acre if the acres planted in cotton were planted in the highest net return commodity per acre between corn and soybeans during the period 1997 through 2008. Our results find that producers in these cotton producing-counties faced sizeable opportunity revenues foregone averaging 43% between 2003 and 2008. Most observers of the cotton industry would argue that these foregone revenues are...

Inorganic fertilizers will play a role in government programs, but whether or not a  single policy is valuable for all farmers depends upon the net gain for the farmers. The research  here seeks to demonstrate how to answer the question “Is fertilizer profitable in Zambia for  maize and cotton in the smallholder sector?” This study identifies the key components determining  profitability and then sets up a framework to evaluate the probability of farmers to obtain  profitable results with fertilizer use on maize and cotton. Several cases are selected and the  results are evaluated. Private profitability for the farmer at market prices is discussed,  leaving social profitability to other researchers.

This paper analyzed the effects of the U.S. domestic offset program on the world cotton markets using a partial equilibrium model following the assumption given by Brown et al. (2010).  The results in our study are largely similar to those of Baker et al. and Brown et al., confirming that study’s findings that ACES, and its domestic offset program in particular, would cause increases in the domestic prices of several agricultural commodities. However, the overall effects of this increase in the world price on total world trade is tempered by increased exports from India, Brazil, Uzbekistan, Australia, and Western &amp; Central African countries.

ADOPTION OF BIOENGINEERED CROPS
Provedor de dados: 31
Autores: Fernandez-Cornejo,   Jorge; McBride,   William D.
Use of crop biotechnology products, such as genetically engineered (GE) crops with input traits for pest management, has risen dramatically since commercial approval in the mid-1990s. This report addresses several of the economic dimensions regarding farmer adoption of bioengineered crops, including herbicidetolerant and insect-resistant varieties. In particular, the report examines: (1) the extent of adoption of bioengineered crops, their diffusion path, and expected adoption rates over the next few years; (2) factors affecting the adoption of bioengineered crops; and (3) farm-level impacts of the adoption of bioengineered crops. Data used in the analysis are mostly from USDA surveys.

POTENTIAL IMPLICATIONS OF PRODUCTION VARIABILITY ON AGRIBUSINESS: THE CASE OF COTTON GINNING IN MISSISSIPPI
Provedor de dados: 31
Autores: Boyd,   Shawn; Hudson,   Darren.
Cotton ginning represents an agribusiness that is heavily dependent on production agriculture.  Recent changes in farm legislation and other government policies may have a long run impact on the variability of cotton production.  This paper examines the potential impacts of increased production variability on the cotton ginning industry in Mississippi.  A programming model is used to derive the optimal structure of the ginning industry under certainty.  Potential implications of production variability are discussed and extensions to the model are proposed.

This paper explores the case for believing endogenous reforms to be more developmental than externally-imposed reforms, by drawing on the recent unorthodox experience of  cotton sector reform in Burkina Faso. We address questions about reform emergence, feasibility, developmental impact, and sustainability. Our analysis, which carefully incorporates local social and political realities, suggests that the urban elites dominating the Burkinabè state favoured a particular cotton reform process, because it provided them with higher rents; while allowing for some rent distribution to the rural world which secured national consensus around reform. Endogenous reforms, though more feasible, are not necessarily more sustainable over time. In Burkina Faso, the...

Stochastic Efficiency with Respect to a Function (SERF) is used to rank transgenic cotton technology groups and place an upper and lower bound on their value. Yield and production data from replicated plot experiments are used to build cumulative distribution functions of returns for nontransgenic, Roundup Ready, Bollgard, and stacked gene cotton cultivars. Analysis of Arkansas data indicated that the stacked gene and Roundup Ready technologies would be preferred by a large number of risk neutral and risk averse producers as long as the costs of the technology and seed are below the lower bounds calculated in this manuscript.

Estimate of the Potential Adoption of Genetically Modified Cotton by Farmers in Southern Spain and its Economic Implications
Provedor de dados: 31
Autores: Gomez-Barbero,   Manuel; Rodgriguez-Cerezo,   Emilio.
This paper analyses the potential adoption and economic on-farm impact of Bt cotton in the Andalusia region (southern Spain). Survey data have shown that, on average, 58% of the responding farmers know about genetically modified (GM) cotton. Another outcome of the survey is that 95% of the farmers declaring that they know about GM cotton would be willing to grow Bt cotton. In the main cotton-producing districts, farmers' attitudes are positive, and they would be willing to adopt the technology. In areas where the crop is more important, the farmers who are willing to adopt Bt cotton represent over 75% of the area under cotton. As regards the on-farm economic impact resulting from a potential adoption, the assessment is that savings on the cost of direct...

The purpose of this study was to analyze structural changes that took place in the cotton industry in recent years and develop a statistical model that reflects the current drivers of U.S. cotton prices.  Legislative changes authorized the U.S. Department of Agriculture to resume publishing cotton price forecasts for the first time in 79 years.  In addition, systematic problems have become apparent in the forecasting models used by USDA and elsewhere, highlighting the need for an updated review of price relationships.  This study concluded that a structural break in the U.S. cotton industry occurred in 1999, and that world cotton supply has become an important determinant of U.S. cotton prices.  China’s trade and production policy also continues to be an...

Toward a Consumer Economy in China: Implications of Changing Wage Policies for U.S. Cotton Exports
Provedor de dados: 31
Autores: MacDonald,   Stephen; Pan,   Suwen; Hudson,   Darren; Tuan,   Francis C.
The effect of a Chinese minimum wage increase on China’s textile market as well as on the world cotton market is evaluated. Based on a Nonlinear Quadratic Almost Ideal Demand System (NQAIDS) model of China’s textile demand, the results suggest that the income elasticity for textiles is around 0.6 in China, and that apparel is less price responsive than home textiles and other textile products.  Simulation results suggest that a minimum wage increase would raise Chinese domestic textile consumption and lower Chinese textile exports. Most of the decline in textile exports by China is offset by expansion in other countries’ domestic textile production and results in a slight increase in world cotton mill utilization and higher clothing prices.

Calculating Cost Savings Per Acre When Harvest Days are Stochastic
Provedor de dados: 31
Autores: Farrell,   Matthew; Ibendahl,   Gregory A.
New cotton harvesters have been introduced that have higher performance rate as well as eliminate extra labor and accompanying equipment. The new machines build partial modules on board the harvester. Higher field efficiency (performance rate) lets a farmers harvest his cotton in a shorter period. Precipitation causes cotton losses in both quality and quantity of the cotton. This paper seeks to measure cost per acre when harvest days are stochastic by using historic precipitation data. Cost per acre will include the cost of losses from a loss function from precipitation. Cost per acre will be adjusted for conventional versus new technology by quantifying the losses that contribute to extra costs of extended harvesting.

YIELD RESPONSE IN PAKISTAN AGRICULTURE: A COINTEGRATION APPROACH
Provedor de dados: 31
Autores: Mushtaq,   Khalid; Dawson,   P.J.
We seek to quantify and evaluate the supply (yield) response of wheat and cotton in Pakistan using cointegration analysis and annual data for 1960-96.  The results reveal that wheat supply is significantly influenced by the prices of wheat, cotton, and fertilizer, the percentage area under high yielding wheat varieties, and the rabi season (winter) water availability.  The cotton supply is found to be significantly influenced by the real cotton price, the real fertilizer price, and in the irrigated area.  The wheat supply was found to be inelastic both in the short- and long-run.  However, cotton supply was elastic in the long-run.

Land Use, Production Growth, and the Institutional Environment of Smallholders: Evidence from Burkinabe Cotton Farmers
Provedor de dados: 31
Autores: Kaminski,   Jonathan; Thomas,   Alban.
The cotton boom in Burkina Faso consisted of a growth in cotton land shares together with an overall increase in total cultivated land. This paper examines the impact of institutional changes in the cotton sector on the evolution of smallholders’ land-use decisions. The empirical analysis is supported by a structural model that takes into account the specific institutional features of the Burkinabè cotton sector and builds upon household level data collected in rural Burkina Faso. We attribute most of the change in land use to the newly established institutional arrangements between producers and stakeholders, mechanization, and slackening of the food security constraint.

Futures Basis for Cotton:  Impact of Globalization and Structural Change
Provedor de dados: 31
Autores: MacDonald,   Stephen; Meyer,   Leslie A.
A model of commodity futures contract basis was developed based on Working’s theory of the price of storage.  An error-correction model was estimated for the basis for the InterContinental Exchange (ICE) #2 cotton contract maturing in December during 2000-08.  The model was also extended to incorporate the impact of changes in market activity that evolved as financial markets and commodity price behavior underwent significant changes after 2005.  The model captured the inversion of basis following the collapse of China’s crop in 2003, but the shock realized during 2008 may have been in part driven by one-time events not included in the model.  Estimates from the error-correction model suggest an extended period for the return of basis to equilibrium,...

Input Credit Provision for Cotton Production: Learning from African Neighbors and Meeting Zambia’s Challenges
Provedor de dados: 31
Autores: Kabwe,   Stephen; Tschirley,   David L.
1. Smallholder farmers in Africa require reliable access to purchased production inputs and credit to take advantage of export opportunities from production of cotton. 2. Unregulated and poorly coordinated markets for cotton, production inputs and credit have too often failed to deliver sustainable production finance to farmers for cotton production resulting in a variety of different approaches to these problems among African countries. 3. Among the countries studied, approaches have varied from State monopolies to private markets with several large firms managing to achieve temporary duopolies. 4. Zambia has been relatively successful in dealing with the input-credit needs of cotton farmers for periods of time but the system has been unsustainable,...

Many studies on the adoption of precision technologies have generally used logit models to explain the adoption behavior of individuals. This study investigates factors affecting the number of specific types of precision agriculture technologies adopted by cotton farmers. Particular attention is given to the influence of spatial yield variability on the number of precision farming technologies adopted, using a Count data estimation procedure and farm-level data. Results indicate that farmers with more within-field yield variability adopted a larger number of precision agriculture technologies. Younger and better educated producers and the number of precision agriculture technologies were significantly correlated. Finally, farmers using computers for...

The Burkinabe Cotton Story 1999-2007: Sustainable Success of Sub-Saharan Mirage?
Provedor de dados: 31
Autores: Kaminski,   Jonathan; Headey,   Derek D.; Bernard,   Tanguy.
Like many other African countries in the 1980s, Burkina Faso was urged to engage in a far-reaching liberalization of its state-led cotton sector. Yet unlike most of its neighbors, the Burkinabè government rejected both the status quo and wholesale liberalization, and instead embarked on a more gradual and sequenced reform path characterized by institutional innovations and partial privatization. Whether the reforms contained genuinely successful elements is therefore an important question, but also a difficult one given the absence of a counterfactual, the confounding influence of exogenous shocks and the recent financial troubles of the sector. To unravel this puzzle, this paper reviews existing evidence linking the reforms to various outcomes, but also...

Irrigation enterprises can be evaluated from a perspective of technical and environmental efficiency. This study determines the technical and environmental efficiency in irrigated cotton enterprises. This is achieved by investigating efficiency at cotton enterprise in the case study area of the Mooki Catchment, located in northern New South Wales. Deep drainage loss which contributes to salinity is considered as an environmental detrimental output. Using four different specifications of Data Envelopment Analysis relative efficiency rankings are determined for each agricultural area in the catchment. This result is then compared to biophysical characteristics from previous studies to help identify the particular features of an area which may influence...

This study aims to analyze the competitivity of the cotton production in Brazil and United States of America (USA) in terms of production costs, taking into consideration the 2003/04 crop season. In Brazil, data were colleted in “panel conferences” in the state of Mato Grosso (Campo Novo do Parecis and Pimavera do Leste) and also in the north of the Parana state. USA’s data came from secondary sources. The results showed that Brazil has a better competitivity, with good productivity, but high costs per hectare. The risk of the culture is high, given the short margins and the sunk costs. In USA, the average productivity is smaller than in Brazil; the costs are relatively high and the margins are negative in most regions. Results show that the sustainability...

Environmental and socioeconomic impact of the new cotton reform
Provedor de dados: 31
Autores: Arriaza Balmón,   Manuel.
Following the decoupling of the cotton subsidies in 2006 the production system has become less intensive in input usage with an average yield reduction of 40 per cent. Albeit the farm income has not been reduced, the reform has had a negative effect on the economy of some rural areas of Southern Spain, where there are few productive alternatives to cotton, with a 39% reduction of direct farm labour. Besides, the reform has been borne by the ginning industry (60% reduction), the agrochemical suppliers and the auxiliary sector. On the other hand, the environment has benefits from the extensification of the cotton production since three quarter of the production is now carried out under integrated production that implies a reduction in the amount of...

Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

The Variable-Rate Input Application Decision for Multiple Inputs with Interactions
Provedor de dados: 31
Autores: Roberts,   Roland K.; English,   Burton C.; Larson,   James A.
Research has evaluated the relative profitability of variable-rate (VRT) versus uniform-rate (URT) application of a single input in fields with multiple management zones. This study addresses map-based VRT decisions for multiple inputs in fields with multiple management zones. The decision-making framework is illustrated for nitrogen and water applied to irrigated cotton in fields with three management zones. Results suggest traditional methods of determining VRT application of a single input may by suboptimal if interactions exist among VRT inputs and URT inputs. Implications are that a systems approach to multiple-input VRT decisions can produce increased net returns to VRT.

Autores: Arriaza Balmón,   Manuel; Gomez-Limon,   Jose Antonio; Gonzalez,   Jose; Ruiz,   Pedro.
Considering the latest reform of the EU's Cotton Regulation of 29th April 2004, which will come into force in the 2006/07 season, we analyse its impact on the cotton production sector of Andalusia. The decoupling of subsidies implies that producers will be entitled to 65 percent of the amount received in the reference period (three years) irrespective of the crop chosen to grow. The remaining 35 percent (slightly higher) is paid as cotton are a payment. In this research, first from a survey carried out in 2004 we obtained six groups of producers using fact or analysis and cluster analysis. Then, based on this characterization, we assess the impact of two policy scenarios: (a) the implementation of the reform without any additional measures, and (b) the...

What Drives Commodity Prices More: Oil Demand or Supply Shocks?

Autores: Mutuc,   Maria Erlinda M.; Pan,   Suwen; Hudson,   Darren.
This paper shows that the response of agricultural commodity prices in the U.S. related to fluctuations in oil prices in the international market may differ greatly depending on whether the increase is driven by demand or supply shocks in the crude oil market. In the long-run, around 2-7 percent of the variability in grains, oilseeds, and cotton prices can be attributed to shocks to aggregate demand for industrial commodities while none can be traced to oil supply shocks.  This paper improves on the lack of economic structure in VAR models employed so far, and on the issue of short datasets, contributes to the nascent empirical evidence, and identifies the transmission of different types of oil price shocks to movements in agricultural prices in a SVAR...

A Case Study of Regulation in Zambia’s Cotton Sector.
Provedor de dados: 31
Autores: Tschirley,   David L.; Kabwe,   Stephen.
Cotton is an unquestioned success of Zambia’s turn towards a market economy. After privatization in late 1994, seed cotton production rose from 32,000 metric tons (mt) to about 180,000 mt a decade later (three-year averages centered on 1994 and 2005). The number of farmers involved in the sector grew similarly, yields trended upwards (though slowly), and the country dramatically improved the quality of its lint, becoming the outstanding performer  in Sub-Saharan Africa in this regard by the mid-2000s. Yet the sector has experienced two serious crashes since reform, both involving rampant credit default by farmers supported with seasonal input credit by ginning companies.

A Cost Function Analysis of Crop Insurance Moral Hazard and Agricultural Chemical Use
Provedor de dados: 31
Autores: Liang,   Yan; Coble,   Keith H.
This paper employs a cost function analysis method to investigate the existence of moral hazard in cotton buy-up insurance. The trans-log cost function estimates of the own-price elasticity of fertilizer, herbicide, and insecticide is -0.222, -0.143, and -0.121, respectively for Mississippi cotton production. Our results found statistically significant relationship between per acre direct cost and cotton buy-up insurance for year 2001 and 2005 in Mississippi. Our results also indicate that moral hazard can either decrease or increase agricultural input usage depending specific production condition in an individual year.  But in general the results support effects smaller than anecdotal evidence would suggest.

Autores: Parvin,   David W., Jr.; Cooke,   Fred T., Jr.; McCarty,   Will.
According to conventional wisdom, low prices favor skip-row planting patterns while high prices favor solid planted cotton. Production costs have been trending upward for many years. Current high production costs have redefined the point at which a low price becomes a high price relative to skip-row versus solid planting pattern decisions. Growers considering a shift from solid to skip-row cotton must be able to produce high yields, more than 90% of the solid yield on a land acre basis.

Autores: Marchant,   Mary A.
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 report analyzes recent structural changes in the world cotton industry and develops a statistical model that reflects current drivers of U.S. cotton prices. Legislative changes in 2008 authorized USDA to resume publishing cotton price forecasts for the first time in nearly 80 years. Systematic problems have become apparent in the forecasting models used by USDA and elsewhere, highlighting the need for an updated review of price relationships. A structural break in the U.S. cotton industry occurred in 1999, and world cotton supply has become an important determinant of U.S. cotton prices, along with China’s trade and production policy. The model developed here forecasts changes in the U.S. upland cotton farm price based on changes in U.S. cotton...

Effects of Seed and Farm Characteristics on Cottonseed Choice:  A Choice-Based Conjoint Experiment in the Mississippi Delta
Provedor de dados: 31
Autores: Banerjee,   Swagata (Ban); Hudson,   Darren; Martin,   Steven W.
Producers’ preferences for cottonseed with respect to price, seed type, yield, and fiber quality are examined by a willingness-to-pay approach via mail surveys.  Results indicate a positive willingness to pay (WTP) for technology relative to conventional cottonseed, and WTP increases with the level of technology.  Yield and quality also show a positive WTP.  Larger farms have a higher WTP for technology, and farms with more farm labor have a lower WTP for technology.  These results suggest economies of size in technology adoption (biotechnology is not size-neutral) and that labor and biotechnology are direct substitutes.

Probit analysis identified factors that influence the adoption of precision farming technologies by Southeastern cotton farmers. Younger, more educated farmer who operated larger farms and were optimistic about the future of precision farming were most likely to adopt site-specific information technology. The probability of adopting variable-rate input application technology was higher for younger farmers who operated larger farms, owned more of the land they farmed, were more informed about the costs and benefits of precision farming, and were optimistic about the future of precision farming. Computer use was not important, possibly because custom hiring shifts the burden of computer use to agribusiness firms.

Mitigating Cotton Revenue Risk Through Irrigation, Insurance, and Hedging
Provedor de dados: 31
Autores: Barham,   E. Hart Bise; Robinson,   John R.C.; Richardson,   James W.; Rister,   M. Edward.
This study focuses on managing cotton production and marketing risks using combinations of irrigation levels, put options (as price insurance), and crop insurance. Stochastic cotton yields and prices are used to simulate a whole-farm financial statement for a 1,000 acre furrow irrigated cotton farm in the Texas Lower Rio Grande Valley under 16 combinations of risk management strategies. Analyses for risk-averse decision makers indicate that multiple irrigations are preferred. The benefits to purchasing put options increase with yields, as they are more beneficial when higher yields are expected from applying more irrigation applications. Crop insurance is strongly preferred at lower irrigation levels.

COTTON SECTOR POLICIES AND PERFORMANCE IN SUB-SAHARAN AFRICA:LESSONS BEHIND THE NUMBERS IN MOZAMBIQUE AND ZAMBIA
Provedor de dados: 31
Autores: Boughton,   Duncan; Tschirley,   David L.; Zulu,   Ballard; Ofico,   Afonso Osorio; de Marrule,   Higino Francisco.
Cotton is one of the most important smallholder cash crops in Sub-Saharan Africa (SSA).  How to ensure input supply, credit recovery and competition is a subject of intense policy debate.  This paper examines the performance of cotton sector development policies in Mozambique and Zambia.  Both countries face the challenge of organizing input supply to farmers in the absence of rural credit markets, and competing in international markets distorted by production subsidies in developed countries.  Both countries privatized cotton ginning in the 1990s.  Emerging from civil war, Mozambique established geographical monopolies to interlink input and output markets and facilitate credit recovery.  In Zambia, the government completely liberalized the cotton sector,...

Adoption of Variability Detection and Variable Rate Application Technologies by Cotton Farmers in Southern United States
Provedor de dados: 31
Autores: Nair,   Shyam; Wang,   Chenggang; Segarra,   Eduardo; Belasco,   Eric J.; Velandia,   Margarita M.; Reeves,   Jeanne M.
A nested logit model was used to analyze the 2009 Southern Cotton Precision Farming Survey to study the impact of farmer and farm characteristics on the adoption of Variability Detection Technologies (VDT) and the adoption of Variability Rate application Technology (VRT) conditioned on the type of the VDT chosen.  The results showed that the farm size and exposure to extension activities are important factors affecting the choice of VDTs.  The farmers adopting both soil and plant based VDTs are more likely to adopt VRT.  The probability of adoption of VRTs was lower for Texas cotton farmers irrespective of the type of VDT adopted.  In general, younger, more educated farmers who use computers for farming operations are more likely to adopt VRT when they...

Conflict, Food Insecurity, and Globalization
Provedor de dados: 31
Autores: Messer,   Ellen; Cohen,   Marc J.
We explore how globalization, broadly conceived to include international human-rights norms, humanitarianism, and alternative trade, might influence peaceful and food-secure outlooks and outcomes. The paper draws on our previous work on conflict as a cause and effect of hunger and also looks at agricultural exports as war commodities. We review studies on the relationships between (1) conflict and food insecurity, (2) conflict and globalization, and (3) globalization and food insecurity. Next, we analyze country-level, historical contexts where export crops, such as coffee and cotton, have been implicated in triggering and perpetuating conflict. These cases suggest that it is not export cropping per se, but production and trade structures and food and...

Autores: Mutuc,   Maria Erlinda M.; Pan,   Suwen; Hudson,   Darren.
Commodity price transmissions between China and the U.S. are examined.  The results indicate that variations in Chinese cotton and soybean prices are transmitted to U.S. cotton and soybean prices while variations in Chinese wheat and rice prices do not get transmitted to U.S. wheat and rice prices. The effects of volatilities in oil prices and in the exchange rate on the price transmission are also assessed.

Framework and Initial Analyses of Fertilizer Profitability in Maize and Cotton in Zambia

Autores: Donovan,   Cynthia; Damaseke,   M.; Govereh,   Jones; Simumba,   D.
The main question which this research originally sought to answer was whether or not inorganic fertilizers are generally profitable used alone on maize, or with pesticides on cotton, for small farmers in Zambia. Rather than give a definitive answer for each Zambian farmer, the authors developed a framework for analysis and applied that framework to locations with sufficient information. Using simple value/cost ratios, researchers estimated the potential profit of fertilizer for those sites. Then, using the distributions of response rates of the crops (incremental yields) found in the trials and output prices based on regional price series, the probabilities are estimated for VCRs, using a minimum of VCR of 2.0 for profitability. The results for selected...

Autores: Chen,   Changping; Ethridge,   Don E.; Fletcher,   Stanley M.
This study provides an analysis of the price-quality relationships of U.S. cotton using primary data collected from textile manufacturers, the end users of fiber.  Hedonic prices of fiber attributes are estimated for three production regions - West, South Central, and South - over the 1992-95 study period.  Results indicate that cotton price is determined by quality attributes and nonquality factors in the end-use market. There are similarities and differences in valuation of fiber attributes based on region of origin of the cotton.

Adoption of herbicide-tolerant cotton and conservation tillage may be simultaneously related.  Bayes' theorem and a two-equation logit model were used to test the simultaneity hypothesis.  Evidence for Tennessee suggests that adoption of these technologies reduced residual herbicide use and soil erosion more than if adoption of these technologies were independent.

U.S. Cotton Subsidies: Drawing a Fine Line on the Degree of Decoupling
Provedor de dados: 31
Autores: Rossi,   Frederick J.; Schmitz,   Andrew; Schmitz,   Troy G.
The impact of the U.S. cotton policy depends on several interrelated factors; how input subsidies interact with producer price supports, producer price expectations, and the extent to which price supports are decoupled from production. Cotton subsidies have a direct impact on world cotton prices, depending on the extent to which price supports are coupled to production. At one extreme, there is a price impact of 12.4% when producers make decisions at the loan rate, but the average price impact is 20.9% when producers make decisions based on the target price. Results are presented for intermediate cases of decoupling.

This study looked at the dynamics of conditional correlations and hedging strategies in the US main cotton producing regions. A two-step procedure was utilized to model, estimate, and analyze volatility, conditional correlations, and the optimal hedge ratios using spot prices in the Delta, Southeast, Southern Plains, and the Southwest regions and the New York commodity exchanges December futures contracts.  The results indicate that volatilities in most of the regions are asymmetric and persistent. The derived conditional correlations and the optimal hedging ratios are dynamic although they do not have unit root. Moreover, the changes in agricultural policies altered the dynamics of correlations and producers' hedging strategies in the Delta, Southeast,...

The Economic Impacts of Biotechnology-Based Technological Innovations
Provedor de dados: 31
Autores: Traxler,   Greg.
Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize) and two traits (insect resistance and herbicide tolerance) account for the vast majority of global transgenic area. While some farmers in some developing countries are benefiting, most do not have access to transgenic crops and traits that address their needs. This paper surveys the level and distribution of the economic impacts of transgenic cotton and soybeans to...

Many studies on the adoption of precision technologies have generally used logit models to explain the adoption behavior of individuals. This study investigates factors affecting the intensity of precision agriculture technologies adopted by cotton farmers. Particular attention is given to the role of spatial yield variability on the number of precision farming technologies adopted, using a count data estimation procedure and farm-level data. Results indicate that farmers with more within-field yield variability adopted a higher number of precision agriculture technologies. Younger and better educated producers and the number of precision agriculture technologies used were significantly correlated. Finally, farmers using computers for management decisions...

Farm Yields and Returns to Farmers From Seed Cotton: Does Zambia Measure Up?
Provedor de dados: 31
Autores: Kabwe,   Stephen; Tschirley,   David L.
1. Farm yields are one key indicator of the productivity of a cotton sector, and an important determinant of returns to farmers (and thus of cotton’s ability to reduce poverty) 2. Zambia’s relatively good performance on input credit provision means that it has been able to raise yields since reforms in 1994; yet the rate of increase has been slow, and yields remain well below those found in countries of West and Central Africa. 3. Average returns to farmers do not appear to be any higher in Zambia, with good performance on input credit provision, than in Tanzania, where input use and yields are low. 4. Zambia’s concentrated structure gives it the potential to substantially increase farm productivity, and for cotton to make but relatively little of this...

ECONOMIC EFFICIENCY IN ORGANIC FARMING: EVIDENCE FROM COTTON FARMS IN VIOTIA, GREECE
Provedor de dados: 31
Autores: Tzouvelekas,   Vangelis; Pantzios,   Christos J.; Fotopoulos,   Christos.
Using recent advances in the stochastic production frontier framework, this paper presents an empirical analysis of technical, allocative and economic efficiency of a sample of organic and conventional cotton farms located in Greece.  The results suggest that both farm types in the sample examined are technically, allocatively and economically inefficient.  Farmer's age and education and farm size are important factors in explaining differentials in efficiency estimates.  In comparative terms, organic farms exhibit lower efficiency scores vis-à-vis their conventional counterparts in terms of technical and economic efficiency; regarding allocative efficiency both farm types are almost equally inefficient.  Low efficiency scores in both types of farming may...

Autores: Roberts,   Roland K.; English,   Burton C.; Gao,   Qi; Larson,   James A.
If adoption of herbicide-resistant seed and adoption of conservation-tillage practices are determined simultaneously, adoption of herbicide-resistance seed could indirectly reduce soil erosion and adoption of conservation-tillage practices could indirectly reduce residual herbicide use and increase farm profits. Our objective was to evaluate the relationship between these two technologies for Tennessee cotton production. Evidence from Bayes' theorem and a two-equation logit model suggested a simultaneous relationship. Mean elasticities for acres in herbicide-resistance seed with respect to the probability of adopting conservation-tillage practices and acres in conservation-tillage practices with respect to the probability of adopting herbicide-resistance...

This study evaluates all USDA cotton supply and demand estimates for the United States and China (including unpublished price forecasts) from 1985/86 through 2009/10 for accuracy and efficiency. Results reveal that at every stage of the forecasting cycle forecast smoothing was the most widespread and persistent type of inefficiency observed in most U.S. variables. Correlation with past errors indicated the tendency to repeat past errors in most cases. Tendency to overestimate growth was also found. Bias was uncommon and limited to several cases of overestimation of China’s exports and U.S. price and underestimation of China’s domestic use. While forecasts of China’s imports and endings stocks improved, U.S. price and ending stock forecast errors became...

We used survey data collected from cotton farmers in 12 southern U.S. states to identify factors influencing cotton farmers’ decisions to adopt precision farming. Using a seemingly unrelated ordered probit model, we found that younger, educated and computer literate farmers chose precision farming for profit reason. Farmers who perceived precision farming to be profitable adopt it to be at the forefront of agricultural technology. We also found that farmers who were concerned with environment emphasize precision farming adoption as a reason to improve environmental quality. Our results also indicate that farmers in coastal states such as Alabama, Mississippi, and North Carolina chose environmental benefits as a reason for precision farming technology...

INTERFIBER COMPETITION IN TEXTILE MILLS OVER TIME
Provedor de dados: 31
Autores: Zhang,   Ping; Fletcher,   Stanley M.; Ethridge,   Don E.
Cotton and synthetic fiber competition in textile mills between 1961-1990 was examined using a time-varying parameter regression model.  Results indicate that the structure of demand for cotton is not stable and cotton's share responses to changes in the prices of cotton and synthetic fiber vary over time.  Cotton and synthetic fiber competition in textile mill use is essentially between cotton and noncellulosic fiber.  Cellulosic fiver is not a cotton competitor.

This paper shows that the response of cotton prices in the U.S. to fluctuations in oil prices in the international market may differ greatly depending on whether the increase is driven by demand or supply shocks in the crude oil market. In the long-run, around 3 percent of the variability in cotton prices can be attributed to shocks to global demand for industrial commodities while none can be traced to oil supply shocks.

THE COTTON ACREAGE EFFECTS OF BOLL WEEVIL ERADICATION: A COUNTY-LEVEL ANALYSIS
Provedor de dados: 31
Autores: Dumas,   Christopher F.; Goodhue,   Rachael E.
The success of the Boll Weevil Eradication (BWE) Program is believed to be one factor underlying the recent increase in cotton acreage in the Southeast.  We find weak evidence that the initial, eradication phase of the BWE program decreases cotton acreage, and strong evidence that the second, maintenance phase of the program increases acreage.  The full benefits associated with a BWE program may not become apparent until acreage adjustments occur, four to five years after program initiation.  Our results indicate that for a representative sample county neglecting acreage effects may lead to underestimation of BWE program net benefits by 9 percent-12 percent.

Adoption of precision agriculture technology has arrived considerable attention, but abandonment has received little.  This paper identified factors motivating adoption and abandonment of precision soils sampling in cotton.  Younger producers who farmed more cotton area, owned more of their cropland, planted more non-cotton area, or used a computer were more likely to adopt precision soil sampling.  Those with more cotton area or who owned livestock were more likely to abandon, while those who used precision soil sampling longer, or used variable-rate fertilizer application were less likely to abandon precision soil sampling.

Assessing the Competitiveness of Indian Cotton Production: A Policy Analysis Matrix Approach
Provedor de dados: 31
Autores: Mohanty,   Samarendu; Fang,   Cheng; Chaudhary,   Jagadanand.
This paper uses a modified policy analysis matrix (PAM) approach to assess the efficiency of cotton production in five major producing states in India. The results indicate that cotton is not efficiently produced in the second largest cotton producing state in the country. Without government interventions, it is likely that acreage will move away from cotton to more profitable crops such as sugarcane and groundnut in this state. In addition, it is also concluded that cotton is not the most efficiently produced crop in the other four states; however, there is at least one crop in each state which is less efficiently produced than cotton. These findings suggest that Indian policies directed at maintaining the availability of cheap cotton for the handloom and...

MEASURING INEFFICIENCY IN THE PRESENCE OF AN EXPORT TAX, AN IMPORT TARIFF, AND A STATE TRADING ENTERPRISE
Provedor de dados: 31
Autores: Schmitz,   Troy G.
Agricultural sales cooperative unions (ASCUs) in Turkey are heavily influenced by both domestic and international government policies.  Both export taxes and import tariffs are used as policy tools to regulate cotton markets.  Domestic price support programs, water subsidies, fertilizer subsidies, and credit subsidies have also been used as domestic policy tools.  These types of subsidies are not uncommon among developing countries.  This paper provides empirical estimates of the degree of economic inefficiency associated with government intervention in Turkish cotton markets.  A two-region partial equilibrium model of cotton exports and imports is developed under the "small country assumption" to obtain empirical estimates of the deadweight welfare loss...

Greek cotton farmers' supply response to partial decoupling of subsidies
Provedor de dados: 31
Autores: Rozakis,   Stelios; Tsiboukas,   Kostas; Petsakos,   Athanasios.
A mathematical programming model based on a countrywide sample of farms is used to assess the impacts of the new C.A.P on the supply of the cotton sector in Greece. Results show a decrease in cotton cultivated area along with the introduction of a new production system called "semi-abandonment cotton". Farm income is practically unchanged, largely due to the decoupled payments. When these payments are not considered, farm income turns negative in some cases, thus leading towards abandonment of activities.

Migration and dispersal of Anthonomus grandis (Coleoptera: Curculionidae) in South America
Provedor de dados: 99
Autores: Stadler,Teodoro; Buteler,Micaela.
This study discusses the dispersal of Anthonomus grandis Boheman, the cotton boll weevil, in Argentina, Brazil, Paraguay and Bolivia, exploring the ecological and physiological factors that have made the dispersal and establishment of this insect in South America so successful. The boll weevil's phenotypic plasticity is represented by its flexible developmental time, its multivoltine life cycle with several overlapping generations, its capacity to feed on pollen from diverse botanical families as well as from non pollen food sources and its ability to migrate and disperse aided by winds. These characteristics make it a key pest for cotton. Probable overwintering «hot spots» for the boll weevil were identified in Misiones-Argentina, where large numbers of...

Autores: Pereira,Alexandre Igor de Azevedo; Ramalho,Francisco de Sousa; Zanuncio,José Cola.
Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) is an important biological control agent of the cotton leafworm [Alabama argillacea (Hübner)] in the cotton crops in Brazil. The use of selective products such as pyrethroids has been emphasized in this agroecosystem. Then, the susceptibility of the predatory stinkbug P. nigrispinus to the pyrethroid insecticide gamma-cyhalothrin was studied in the laboratory. Nymphs and adults of the predator were exposed to seven concentrations of the gamma-cyhalothrin via topical contact and ingestion through treated water. The concentrations studied of this insecticide via topical application were relatively harmless for adults of P. nigrispinus (females: LC50 = 143.5 ppm a.i., and males: LC50 = 145.1 ppm a.i.)...

ABSTRACT: The root system architecture (RSA) of plants and its functioning play a fundamental role in a number of plant growth mechanisms including water and nutrient uptake. Optimization of the RSA is important for stable and increased plant productivity under adverse conditions. Despite its great importance, studying the RSA is notoriously laborious because of the difficulty of accessing the rooting system of plants. We developed a root phenotyping platform, PhenoRoots, which allows for the non-invasive study of plant RSA. The system was built using inexpensive material and was designed to provide medium throughput. Substrate or soil-filled rhizotrons are used to grow plantlets, whose roots are directly visible through a glass plate. An experiment...

Cotton damage from cotton jassid (Amrasca biguttula Ishida) becomes very serious problem because of 50-100% reduction of cotton yield. In order to reduce more systemic insecticide used for jassid control, jassid tolerant hairy leaf cotton varietal improvement was conducted at Nakhon Sawan Field Crops Research Center in 1997. The hairy leaf variety, IRMA1243, exhibiting jassid tolerance, was crossed with smooth leaf and leaf roll resistant Tak Fa 2, which has high yield and good fiber quality. Thereafter, plants were selected using bulk method in F2-F4 generations, followed by plant-to-row or pure line selection in F5-F6 generations based on hairy leaf with jassid tolerance, leaf roll disease resistance and high yield under non systemic-insecticide...

The initial goal of this study was to measure the efficiency of carbon isotope discrimination (Δ) in distinguishing between cotton plant genotypes subjected to two water regimes. In addition, ∆ measurements, leaf water potential and gas exchange ratios were monitored. Using Brazilian breeding lines, this study also tested the usability of ∆ as a proxy for selecting high-performing yield components in cotton plants grown in unfavorable conditions, particularly water deficiency. For these experiments, ∆ and yield components were measured and their correlations analyzed. Differences among cotton genotypes for Δ (p &amp;lt; 0.0001) were verified, and it was found that this variable was significantly correlated with gas exchange. There was a significant...

Analytical techniques used to extract chlorophyll from plant leaves are destructive and based on the use of organic solvents. This study proposes a non-destructive quantification of the photosynthetic pigment concentration in cotton leaves using two portable chlorophyll meters, the SPAD-502 and the CLOROFILOG 1030. After obtaining 200 leaf discs, each with an area of 113 mm2, the greening rate in each disc was determined by the average of five readings from both meters. Immediately after measurement, 5 mL of dimethyl sulfoxide (DMSO) was added, and the samples were kept in a water bath at 70ºC for 30 min. After cooling, 3 mL of the liquid extract was used for analyses by spectrophotometry at 470, 646 and 663 nm. Mathematical models were adjusted from...

ABSTRACT The oxidative stability of linseed (L), cotton (A), and coconut (C) oils, as well as of linseed:cotton (LA), linseed:coconut (LC), and linseed:cotton:coconut (LAC) compound oils was evaluated under accelerated storage at 60°C/20 days. Coconut oil showed to be rather stable, mainly due to low levels of peroxides, conjugated dienes, ρ-anisidine, and long induction period. In addition, along with cotton oil, it improved the stability of linseed oil in the formulation of LAC compound oil. As to fatty acid profile, the compound oils showed to be composed mainly by unsaturated fatty acids. Cotton and coconut oils presented higher retention of total phytosterols, 78.87 and 76.16%, respectively, after 20 days of storage, when compared to linseed oil. The...

ABSTRACT - This work was designed to evaluate the residual action of the insecticides trichlorfon, triflumuron, endosulfan, fenpropathrin, chlorpirifos, tebufenozide and esfenvalerate, sprayed on cotton plants, to second-instar larvae of Chrysoperla externa (Hagen, 1861), under greenhouse conditions. The experimental design was completely randomized with ten replicates. Three larvae were released on each plant, in the 1st, 12th and 23rd day after pesticides spray. Tebufenozide and esfenvalerate were little persistent (class one), while trichlorfon, triflumuron and endosulfan were slightly persistent, decreasing the survival of C. externa larvae over 30%, up to 14 days after spray. Fenpropathrin and chlorpirifos caused mortality over 30%, up to 25 days...
