Conference Paper 1992

Autor: Kouame, C. Hoefs, S. Powell, J.M. Roxas, D. Renard, C.

The increasing interest in crop-livestock integration in sub-Saharan Africa has emphasised the beneficial uses of forage legumes in cereal-based cropping systems. Forage legume-cereal cropping systems were evaluated in 1989 and 1990 at the ICRISAT (International Crops Research Institute for the S...

This paper is comprised of five parts. The first part discusses the role of legumes in sustainable soil management and crop-livestock production. In this part, strategic use of legumes, selection of forage legumes to sub-optimal soil conditions, use of appropriate rhizobium, response of legumes t...

Livestock manure is an important source of nutrients for crop production in semi-arid West Africa. An assessment of the potential of manure to sustain crop production calls for an estimation of the amounts of manure that could be produced and captured and the feed resources required to maintain l...

The sustainability of nutrient transfers in integrated rangeland/cropland systems of the Sahel was examined in relation to the impact of livestock. Rangeland nutrient balances are considered in equilibrium whereas croplands lack the internal capacity to replenish nutrient off takes in grain and c...

Integrated natural resource management (INRM) is considered in the context of evolving crop-livestock systems in West Africa and recent Developments in approaches for INRM research. The major crop-livestock systems, ranging from extensive grazing, through integrated crop-livestock farming to inte...

Animal manure is of vital importance to soil-fertility maintenance in semi-arid West Africa due to its intrinsic value as a soil amendment and because of the low level of inorganic fertiliser use. This paper provides a regional overview of manure utilisation for food crop production. Results of e...
