Crop Residue Management in Conservation Agriculture Systems in Zimbabwe Smallholder Farming Sector: Importance, Management Challenges and Possible Solutions
Conservation agriculture (CA) is promoted as a cropping system that has potential to alleviate poor crop yields in smallholder farming while protecting the environment. It involves maintenance of permanent soil cover, diverse crop rotations and/or interactions; and minimum soil disturbance. CA is associated with crop residue management challenges due to low crop biomass yields and crop-livestoc...
متن کاملCrop–livestock interactions in agricultural and pastoral systems in West Africa
Driven by population pressures on natural resources, peri-urban pastoralists in the Far North Province of Cameroon have recently intensified livestock production in their traditional pastoral system by feeding their cattle cottonseed cakes and other agricultural byproducts to cope with the disappearance of rangelands typically available through the dry season. Although the crop–livestock intera...
متن کاملThe crop-livestock subsystem and livelihood dynamics in the Harar Highlands of Ethiopia
Introduction Policy makers and extension planners often assume smallholder mixed farming systems are incapable of evolving fast enough to meet growing food demands and that livestock are relatively unimportant to household food production or welfare (FDRE, 1994), except for intensive units. The resulting policy promotes substitution of either intensive cropping or livestock production in place ...
متن کاملSilvopastoral Systems as a Strategy for Diversification and Productivity Enhancement from Livestock in the Tropics
Silvopastoral systems present important opportunities for increasing food production from animals. This is justified by the widening gap between production and consumer requirements, and the inability of domestic supplies to meet the projected demand up to year 2020 for foods of animal origin. Increasing productivity from animals thus necessitates the development of all possible avenues of food...
متن کاملA framework for assessing crop production from rotations
Organic farming systems rely on the management of biological cycles for the provision of nutrients, which are crucial to maximising the production from the system. Rotations based on the use of grass-legume leys are central to the concept of organic farming systems, because they have the potential to support both animal production, and a subsequent, exploitative, arable cropping phase. A major ...
