A dynamic model of cotton emergence based on the thermal dependence of malate synthase
Cotton (Gossypium hirsutum L.) is frequently planted when temperatures are not optimal for germination and emergence. Delayed emergence, a common contributor to diminished plant performance later in the season, is often related to nonoptimal temperatures. Improvement of cotton performance requires knowledge of the source, pattern, and magnitude of thermal limitations on seedling metabolism. In ...

GM cotton and its possible contributions to environmental sustainability and rural development in Turkey
Cotton farming in Turkey faces economic, environmental and socioeconomic challenges. Organic cotton has been a successful response that greatly benefited low-input farmers; but, worldwide, it will eventually become a mature niche market with limited growth potential. Since no Genetically Modified (GM) varieties have been approved so far in Turkey, we want to find out how the potential adoption of ...

Perceptions and practices of farmers towards the salinity problem: the case of Harran Plain, Turkey
The Harran region, located in the South-eastern part of Turkey, is facing an increasing salinity problem due to excessive and inefficient irrigation practices. In this paper, we survey 619 cotton producers in the region and analyse their perceptions and practices towards soil salinity. The survey results indicate that formal education and training are the central factors that determine the ...

Rural transformation in Turkey 19802004: case studies from three regions
This paper focuses on the economic dimension of rural transformation (or structural transformation) in Turkey. It investigates the development of labour demand and supply in rural areas over the past two decades. For that purpose, three longitudinal case studies were conducted in three different regions of Turkey. This paper concludes that the lack of substantial labour transfer from agricultural ...

Bt-cotton boosts the gross margin of small-scale cotton producers in South Africa
This paper explores some of the issues involved in the Genetic Modification (GM) debate by focusing on one crop that has been modified for pest resistance, cotton (Gossypium hirsutum), and commercially released to small-scale farmers in the Makhathini Flats, KwaZulu Natal, the Republic of South Africa. This was the first commercial release of a GM variety (Bt-cotton) in Sub-Saharan Africa, and ...

Agricultural biotechnology in India: ethics, business and politics
This paper deals with the case of Bt cotton in Gujarat, India, as an illustration of how public policy chickens out when large-scale violation of ethical and scientific norms takes place with positive business outcomes. Entrepreneurial spirit has created a unique case of farmer participatory research whereon farm crosses are being made between Bt cotton varieties and other released varieties. New ...

Economic cost of non-adoption of Bt-cotton in West Africa: with special reference to Mali
A major public policy issue in West Africa is whether or not, and how, to introduce Bt-cotton in the region. The implications of non-adoption may be more significant than, for example, the issues often raised concerning cotton subsidies in advanced countries. This paper provides estimates of the potential benefits from Bt-cotton if introduced in West Africa. Our analysis shows significant ...

Nitrogen mineralization in a pecan ( Carya illinoensis K. Koch)–cotton ( Gossypium hirsutum L.) alley cropping system in the southern United States
Information on temporal and spatial patterns of N mineralization is critical in designing tree-crop mixed systems that could maximize N uptake while minimizing N loss. We quantified N mineralization rates in a pecan (Carya illinoensis K. Koch)–cotton (Gossypium hirsutum L.) alley cropping system in northwestern Florida with (non-barrier) and without tree-crop belowground interactions (barrier ...

Composting cotton industry by-products. Evaluation of Use of cotton solid wastes compost as a substrate.
The textile industry at region of Entre Douro e Minho is located at Ave valley and is responsible for a great amount of cotton solid wastes. Currently these wastes, which are characterised by a high C/N ratio and some salinity, are directly applied to soil by farmers without any previous treatment (Zucconi et al, 1981). Extraction of peat causes environmental damage (Smith, 1992) which leads to ...
