Human population pressures upon land resources have increased the need to assess impacts of land use change on soil quality. In order to assess effects of land use changes on soil quality properties in a tropical forest ecosystem of Bangladesh, soil samples were collected from adjacent well-stocked Shorea robusta natural forest, land reforested with Acacia, grassland and cultivated land. Land u...

Simulation models of leaf area index (LAI) and yield for cotton can provide a theoretical foundation for predicting future variations in yield. This paper analyses the increase in LAI and the relationships between LAI, dry matter, and yield for cotton under three soil conditioners near Korla, Xinjiang, China. Dynamic changes in cotton LAI were evaluated using modified logistic, Gaussian, modifi...

Front Line Demonstrations (FLDs) have been proved the best means for creating awareness of new development in technology generation and to assess various socio-economic variables affecting adoption level farmers as regular feedback is a necessary component these demonstrations. KVK Khargone district has organizing FLDs on Bt-cotton, therefore keeping view researcher’s interest research entitled...

alborz province with an area of about 5121.7 km2 has about 0.31% of the total area of the country. the total arable area of the province is about 48954 hectares. water, land and capital are the most important factors for agricultural production. by understanding the subjective beliefs, decision-making criteria and economic incentives of local farmers, the priority of crops can be achieved with ...

Double direct seeding of cotton (with wheat or rapeseed) is a new method for cotton-growing regions in the Yangtze River Basin to adapt development mechanization. It would help reduce manual labor, optimize amount nitrogen fertilizer be used, physical and chemical production costs, improve benefits fields. We selected five counties from major cotton-producing areas Hubei Province three consecut...

This paper, with No.22 State Farm, Agricultural Division No.2, XPCC as the example and under support of GIS, takes cultivated land plot as the evaluation unit and chooses 13 influence factors from five aspects of nutrient of cultivation layer, physical and chemical properties of cultivation layer, soil management, climate conditions and obstacle factor to establish desert oasis cultivated land ...

A field study was conducted to compare the formationand bacterial communities of rhizosheaths of wheat grown under wheat-cotton and wheat-rice rotation and to study the effects of bacterial inoculation on plant growth. Inoculation of Azospirillum sp. WS-1 and Bacillus sp. T-34 to wheat plants increased root length, root and shoot dry weight and dry weight of rhizosheathsoil when compared to non...

More than half of the world’s cotton lint is produced in Asian countries: China contributes 24 percent (6.3 Mt of raw cotton), India 16 percent (4.1 Mt) and Pakistan 10 percent (2.5 Mt) to the total world cotton production (Kooistra, 2006). The cotton-based farming systems differ for management practices and cropping pattern across and within countries, however in common they have the size ofte...
