Objectif
1.) Development of improved soil management, tillage and weed control systems that conserve scarce resources including energy inputs. * 2.) Identification and specification of conservation tillage, weed control and water harvesting practices that are adoptable by Arid and Semi Arid Land (ASAL) farmers in Zimbabwe and similar ecological regions. * 3.) R&D multidisciplinary collaboration between Zimbabwe, UK and other institutions in Africa.

Descriptif
Population pressures within Southern Africa are forcing people to increasingly crop land of a marginal and fragile nature where the risk of environmental degradation is high and current yields are low. Much of this land is in harsh water scarce semi-arid regions and the existing crop husbandry is often not appropriate as it has generally been imported from higher potentail areas. Previous tillage research only provides limited information for these drier areas as it has concentrated on commercial farming in higher potentail areas with tractors. It is only in the last ten years or so that attention has increasingly focussed on the tillage requirements of these small scale farmers. There is still much to learn about the basic environmental, social and technical constraints to crop production in terms of : —climate and the lack of available water to the crop —cultivation/management requirements for different soil types under various rainfall and cropping regimes —inability of resource poor farmers to achieve timeliness of planting and —the problem of effectively controlling weeds. This project will investigate the impact of various tillage and weeding practices on the conservation of soil water for crop growth. Recommendations eventually resulting from this research could involve farmers in changes to existing tillage and conservation systems and cropping methods.
