Soil fertility is declining in most agro-ecosystems in sub-Saharan Africa, and incorporation of forage legumes into production systems to utilize the nitrogen fixed by the legumes could alleviate the problem, if efficient nitrogen-fixing legumes are used. The amounts of nitrogen fixed by Lablab, ...

The majority of soils in Africa are P-deficient, but the high cost of conventional, water-soluble P fertilisers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The relative agronomic effectiveness of unacidulated (RP), 25 percent partially acidulated (PARP25)...

Cereal-legume intercrops are quite common in sub-Saharan Africa. However, most of the research in this area has concentrated on grain legumes or pasture grass-legume mixtures. More recently, attention has been called to the integration of forage legumes with livestock production. While it is know...
