It is sometimes argued that women play a more important role in seed and diversity management than men,and that women have greater abilities in managing crop diversity. In The Gambia, men and women also havethe belief that women are better in managing and identifying varieties than men. This article focuses on therole of gender in farmer management of crop diversity in two crops...

In recent years, agricultural growth in China has accelerated remarkably, but most of this growth has been driven by increased yield per unit area rather than by expansion of the cultivated area. Looking towards 2030, to meet the demand for grain and to feed a growing population on the available arable land, it is suggested that annual crop production should be increased to around 580 Mt and th...

The University of Hertfordshire, funded by MAFF and in collaboration with ADAS and IACRRothamsted, is currently developing a computer-based decision support system to encourage and enhance best practice within arable agriculture such that environmental protection can be given a high priority without jeopardising profitability. A significant part of this system is focused towards the use and man...

In cotton and cereals production systems, the most important cause of soil fertility degradation is the inappropriate crop residues management. In a long-term experiment carried out from 1982 to 2012, the effects of crop residues management (CRM) during 30 years on soil chemical properties and crops yields were evaluated in a cotton-cereals rotation. The experimental design was nonrandomized bl...

Background: Soils are important global carbon pools that are under threat from intensive land use through a variety of agricultural practices. Sustainable management of agricultural soils may have the potential to mitigate climate change through increased carbon sequestration and increase their fertility. Among management practices to increase carbon sequestration, crop rotation designs have of...

As the world's population increases, marginal lands such as drylands are likely to become more important for food production. One proven strategy for improving crop production in drylands involves shifting from conventional tillage to no-till to increase water use efficiency, especially when this shift is coupled with more intensive crop rotations. Practices such as no-till that reduce soil dis...
