"The effects on cotton production due to climate change : an assessment on water availability and pesticide use in two different cotton growing regions in India". Thesis, Stockholm University, Stockholm Resilience Centre, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:su:diva-7824.
Texto completoAccording to several scientific reports, climate change will have an impact on water provision and thus agriculture, which depends on soil moisture for plant survival. India is a country that is heavily dependent on agriculture as a source of income. One of the country’s future challenges is securing water for irrigation. Cotton in India is an important cash crop which is grown under high evapotranspirative demand, using about 15% of the national water resources, making the crop vulnerable to changes in water availability.
The purpose of this study is to evaluate the resilience of cotton production with regards to water availability and pesticide use in Punjab and Andhra Pradesh. Three aspects of resilience: latitude, resistance and precariousness has been used to analyse three variables, precipitation, irrigation and pesticide in order to understand how these cotton growing systems are going to be affected by climate change. By bringing together existing data from several scientific reports and governmental websites, assumptions could be made whether these systems are resilient or if they are reaching a threshold. The results show that the cotton growing regions of Punjab are highly vulnerable when it comes to water provision in the region and that they might be reaching a threshold. Changes in climate are predicted to affect precipitation and temperature in the area, which in time might ultimately affect water resources in the region. Groundwater depletion and water logging are already prevailing problems in the area where almost all cotton production is irrigated. Cotton farmers in Andhra Pradesh are struggling with pest infestation which induces them to overconsume pesticides, affecting not only water quality in the area, but also farmers’ livelihood. It is likely that climate change will not minimize the outbreaks; on the contrary it might benefit some pests, which might increase the consumption of pesticide in the region. Coastal districts are more exposed to extreme weather which can harm cotton cultivation.

O presente trabalho teve por objetivo avaliar o comportamento de plantas de algodão submetidas à aplicação de doses de cloreto de mepiquat e precipitações pluviais ocorrendo em diferentes momentos após a aplicação do produto. Procurou-se ainda desenvolver um método simples de estimativa da dose do produto a ser aplicada. Os tratamentos foram constituídos de três doses do regulador a base de cloreto de mepiquat (PIX®): 7,5, 15,0 e 22,5 g ha-1 e seis intervalos de tempo para aplicação de chuva simulada de 20 mm de intensidade: 0, 1, 3, 6, 12 e 24 horas, mais um tratamento sem a aplicação de chuva. Foram utilizados vasos de 12 litros de capacidade e seis sementes pré-germinadas com posterior desbaste para duas plantas por vaso. O delineamento experimental utilizado foi o inteiramente casualizado com quatro repetições. Os parâmetros avaliados foram: altura de plantas, número de ramos reprodutivos, massa de matéria seca, retenção de estruturas reprodutivas (coleta de estruturas reprodutivas e estruturas perdidas) e área foliar. Os resultados mostraram que o efeito do regulador foi prejudicado pela ocorrência de chuva nos momentos mais próximos a sua pulverização. As maiores doses mostraram ter efeito mais significativo nos parâmetros de crescimento avaliados, mostrando que chuvas ocorridas em momentos mais próximos após a pulverização causam maior comprometimento da ação do regulador nas plantas de algodão. É possível calcular a dose de regulador a ser aplicada conhecendo-se a altura atual das plantas.
The research had the objective to evaluate the behavior of cotton plants submitted to the application of doses of Mepiquat Chloride and precipitations happening in different times after the application of the product. A tentative for developing a simple method for estimating the dose of the product that would be applied was tried. The treatments were constituted of three doses of the growth regulator, mepiquat chloride (PIX®): 7,5, 15,0 and 22,5 g ha-1 and six time intervals for the application of simulated rain of 20mm of intensity: 0, 1, 3, 6, 12 and 24 hours, and one treatment without rain. Plots of 12 liters of capacity and six pre-germinated seeds were used with subsequent rough-hewing for two plants per plot. The experimental design used was the completely randomized with four replications. The parameters analyzed were: height of plants, number of reproductive branches, weight of dry matter, collecting of reproductive structures and lost structures, and leaf area. The results showed that the effect of the growth regulator was harmed by the rain occurrence in the closest moments of the application of the growth regulator. It was possible to calculate the regulator dose to be applied knowing the actual height of the plants.

O objetivo do presente trabalho foi avaliar o efeito das subdoses de 2,4-D e cloreto de mepiquat nas características vegetativas e produtivas de dois cultivares de algodão. O experimento foi conduzido durante o período de novembro de 2012 a maio de 2013 e novembro de 2013 a maio de 2014. O delineamento experimental foi o de blocos ao acaso em um esquema fatorial 6 x 2 x 2, com 4 repetições, totalizando 96 parcelas, perfazendo 24 tratamentos: a testemunha e cinco subdoses do herbicida 2,4-D: 0,68; 1,36; 2,04; 2,72 e 3,40 g equivalente ácido (e.a.) por ha -1, com e sem aplicação de cloreto de mepiquat na dose 200 mL ha -1 nas cultivares FMT 701 e Fibermax 966 de algodoeiro. Aplicou-se as subdoses de 2,4-D aos 45 dias após a emergência da planta (d.a.e.) e o regulador de crescimento aos 70 d.a.e. Constatou-se que a utilização do regulador de crescimento (cloreto de mepiquat) na dose 200 mL ha -1 foi eficiente no controle do desenvolvimento da planta em relação a variável altura de planta no dois anos de estudo. Para o cultivar de porte baixo, a aplicação das subdoses crescente de 2,4-D proporciona um incremento na altura de planta. Com o aumento das subdoses de 2,4-D, ocorre um incremento no número de estruturas reprodutivas para o cultivar FMT 701. A aplicação de subdoses de 2,4-D na faixa de 1,75 a 1,90 g e. a. ha -1 propicia um aumento de produtividade de algodão em caroço para a cultivar FMT 701. Para a cultivar Fibermax 966 a subdose de 1,75 propicia um incremento na produtividade de algodão em caroço. A cultivar FMT 701 obteve maior altura de planta, diâmetro do caule, quantidade de ramos reprodutivos, capulhos por planta e produtividade de algodão em caroço comparado com a cultivar Fibermax 966 nos dois anos agrícolas
Due to expansion of cotton production, research with growth regulators and sublethal rates of herbicide are being developed to improve levels of crop productivity. The aim of this study was to evaluate the effect of sublethal rates of dichlorophenoxyacetic acid and mepiquat chloride on vegetative and productive characteristics of two cultivar of cotton plant. The experiment was conducted during the growing season of 2012/2013 and 2013/2014. The experimental design was a randomized completely blocks design in a factorial system 6 x 2 x 2 with 4 replications, consisting 96 plots, with the amount of twenty four treatments: one control and five rates of 2,4-D: 0.68, 1.36, 2.04 2.72 and 3.40 g equivalent acid (e.a) by ha -1, with and without application of mepiquat chloride in the level 200 mL ha-1 in the cultivar FMT 701 and Fibermax 966 cotton. Applied to the doses of 2,4-D at 45 days after plant emergence (d.a.e.) and the growth regulator to 70 d.a.e. The result showed that the use of the growth regulator (mepiquat chloride) at a dose 200 mL ha -1 was effective in controlling plant development in relation to plant height on the two-year study. For the small size of cultivar, the application of increasing doses of 2,4-D provides an increase in plant height. With increasing doses of 2,4-D, there is an increase in the number of reproductive structures for cultivating FMT 701. The application doses of 2,4-D in the range of 1.75 and 1.90 g. The. ha - 1 provides an increase of seed cotton productivity to grow FMT 701. To cultivate Fibermax 966 to sub-dose of 1.75 provides an increase in cotton productivity in seed. Cultivar FMT 701 obtained the highest plant height, stem diameter, number of reproductive branches, bolls per plant and cotton productivity in seed compared with the cultivar Fibermax 966 in both years

The cotton crop has a large number of insects that can damage the production. The caterpillar Pseudoplusia includens (Walker) most commonly found in soybean, has been highlighted today in the Midwest region of Brazil, due to new systems of crop rotation, soybean-cotton. One of the major technological advances is the availability of transgenic cultivars resistant to some species of defoliating insect pests, but some species considered target technology, has survived and concerned farmers. This study aimed to evaluate the main biological aspects P. includens feed by leaves of four cotton cultivars, as well as studying the effect of transgenic NUOPAL cultivar, on behavior, survival and development of the insect. Furthermore, were evaluated the attractiveness and foliar consumption by larvae to the cultivars. Another objective was to evaluate the vertical distribution of larvae of P. includens in transgenic cultivar WideStrike and its isoline commercial FM 993. Were used a completely randomized design, using treatments with cultivars DeltaOPAL, NUOPAL, FM 993 and FM 910, with 60 replicates for the antibiosis experiment. In the test of non-preference for feeding caterpillars, was used completely randomized design with 10 replicate with the same cultivars. For the vertical distribution was used as a randomized block design in a split-plot, with 06 treatments (3 parts of plants x 2 leaf surface), and 40 replicate. The data were transformed into (x +0.5)1/2 and subjected to analysis of variance and treatments means were compared by Tukey test at 5% probability.

In the present study, the environmental damages caused by the cultivation of cotton from the hyperconsumerism and solid textile residues of this natural fiber of greater world-wide importance are analyzed. At first, we analyzed the Risk Theory, drawn as a defining and fundamental point for the course of the study, and presented as adequate to support the analysis of the environmental risks and damages caused by the production of cotton, its residues and hyperconsumption . In a second step, we work on the ways of producing cotton in Brazil, bringing the benefits of organic cultivation, and the approach to growing cotton-growing transgenics. It addresses the intense use of pesticides, making difficult the existence of a sustainable cycle. Next, it focuses on the environmental impacts caused by the textile industry, emphasizing the theme of textile solid waste from cotton. The method used is the deductive analytic, based on the exploratory bibliographical research. Finally, it reveals the legal and legal permissibility when hosting the traditional methods used in the development of cotton crops, especially as regards the high level of pesticides. Textile waste from cotton, industry and consumers is little used for social reuse programs; however, they remain a social problem, since the National Solid Waste Policy did not lead to a practical solution. It is recognized that neglect of environmental damage is immense in the risk society of modernity characterized by capitalist advancement. The trajectory of hyperconsumption exposes a behavior centered on social individualism even in the face of recurrent disasters.

Texto completoIn the cotton-growing area of Southern Mali, the different studies conducted explain the growth of the cattle herds' size by the under off-take of the herds by the breeder. The objective of the thesis is therefore to make a diagnosis on the off-take of the cattle herds in the cotton-growing area of Southern Mali and to identify the constraints of the herd off-take. The research methodology combined zoo technical and sociological approach to analyze the practices and the off-take decisions of the breeder's herds. The use of a demographic model permitted to measure the sensitivity of the productivity rate to the different demographic parameters. The valued off-take rate of the herd was of 0.08 year-1. This rate compared to the rate of 0.11 year-1 of the numeric productivity of livestock shows that there is not under off-take of the cattle herds. The processes of animal's off-take imply several decision-makers. However, the different organizational structures and decision don't constitute a hindrance to the animal's off-take. The monetary need is the main reason of animal's sale to face the family's expenses. The rates of off-take and in-take of animals are tie with the herd size and the behaviors of the families. The off-take rate is related to the productivity of the herd. The productivity improvement passes by the reproduction improvement and the proportion of reproductive females in the herd

O presente trabalho teve por objetivo avaliar plantas de algodão submetidas a reguladores de crescimento em função das condições ambientais e de absorção dos produtos quando aplicados ou não com adjuvante vegetal. No primeiro experimento foram avaliadas plantas de algodão submetidas ao regulador à base de Cloreto de Mepiquat e regimes de temperatura dia/noite de 25/15, 32/22 e 39/29 °C. O delineamento experimental utilizado foi o inteiramente casualizado com cinco repetições. Foram avaliados parâmetros de crescimento, retenção de estruturas reprodutivas, fisiológicos e anatômicos. No segundo experimento os tratamentos foram constituídos de uma dose de regulador à base de Cloreto de Mepiquat e chlormequat e correspondente a 15,0 g ha 1 do princípio ativo, aplicado com e sem adjuvante. As plantas foram submetidas à lâmina de chuva correspondente a 30 mm após 0; 1,5; 3; 6; 12 e 24 horas da aplicação do regulador, mais um tratamento sem chuva. O delineamento experimental foi o em blocos casualizados com quatro repetições. Foram avaliados parâmetros de crescimento, estruturas reprodutivas, reposição do regulador lavado pela chuva e concentração do regulador na planta. Além disso, foram realizados testes paralelos que visaram determinar a concentração dos produtos nas plantas e o comportamento das plantas em condições de campo submetidas à lavagem do regulador. O uso de adjuvante siliconado contribuiu de maneira significativa para a permanência e/ou absorção dos produtos pelas plantas de algodão; o melhor regime de temperatura para o desenvolvimento das plantas de algodão, bem como para que o regulador à base de Cloreto de Mepiquat possa ter sua ação expressa da melhor forma, foi a de 32/22°C e a reposição do regulador inicialmente aplicado e lavado por chuva se faz necessária para que as plantas tenham o seu crescimento controlado, o que melhora todo o sistema de produção.
This research had as objective to evaluate cotton plants submitted to plant growth regulators as affected by environmental and uptake conditions when applied with or without adjuvant. In the first experiment, cotton plants were evaluated when they were submitted to mepiquat chloride and temperature regimes, day/night, of 25/15, 32/22 and 39/29 °C. The experimental design was the completely randomized with five replications. Growth, physiological, reproductive structure retention and anatomical parameters were evaluated related to the plant growth regulator uptake. In the second experiment, treatments were constituted by one rate of plant growth regulator mepiquat chloride and chlormequat chloride of 15 g ha-1 of the active ingredient, applied with and without adjuvant on cotton plants. Plants were submitted to simulated rainfall of 30 mm after 1; 1,5; 3; 6; 12 and 24 hours after plant growth regulators application, plus a treatment without rainfall. The experimental design was in randomized blocks with four replications. The parameters evaluated were: plant growth, reproductive structures, reposition of the plant growth regulator washed by the rainfall and concentration of the plant growth regulators in the plant. Besides, parallel tests were carried out which had as objective to determinate the concentration of the products in the plants and plant growth in field conditions submitted to plant growth regulator wash. A silicon adjuvant contributes in a significant way for the product permanence and/or uptake by the cotton plants. The most adequate temperature regime for plant development, as well as, for mepiquat chloride plant growth regulator to express its action was 32/22°C and the reapplication of the regulator rate initially applied and washed by rainfall was necessary, so the plants could have their growth controlled, what optimizes the whole production system.
