Virus diseases of herbaceous legumes have been relatively little studied even though the legumes play an important role in the maintenance of soil fertility and pest/disease management as well as providing fodder in sub-Saharan Africa. Leaf samples exhibiting virus-like symptoms from nine herbace...

Demand for livestock products has been increasing through much of the semi-arid tropics and will likely continue to increase along with the use of purchased feedstuffs. As smallholder livestock systems evolve and become more market oriented, the type of diets fed to livestock may change and the i...

A virus, 750 × 18 nm, was isolated from Centrosema pubescens from Nigeria, causing leaf malformation, mosaic and mottling on the plant. When inoculated on to various test plants, it failed to produce necrotic or chlorotic lesions on Chenopodium amaranticolor, but symptoms of mottling were observe...

Soils of the African savanna are generally deficient in nutrients, a situation that has negative implications on crop and livestock intensification and hence on food security in Africa. The exclusive use of inorganic fertilizers to bring about increased crop production sometimes has negative impa...

Soils of the moist savanna of West Africa are poor in nitrogen; the natural fallow regeneration time has shortened; fertilizer costs and scarcity makes nitrogen (N) fertilizer input inadequate; and crop yields are low. In the region, lablab (Lablab purpureus L., sweet also known as Dolichos labla...

Forage plant evaluation is carried out by many institutions throughout sub-Saharan Africa. However, the approach adopted at various locations varies. This manual outlines standard evaluation methodology, which will enable researchers throughout the region to obtain meaningful results from their f...
