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...

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...

This study links participatory research methods, geographic information systems (GIS) techniques, village and household-level surveys, and a tobit analysis to examine the adoption and impact issues related to a new technology, improved varieties of dual-purpose cowpea (IDPC), developed by Interna...

Rapid growth of the human and livestock populations in sub-Saharan Africa is creating unprecedented increases in food and feed demands. These population pressures on a fixed landbases are likely to promote severe competition for resources and drive agriculture progressively towards intensificatio...

In the process of developing an improved fallow system based on forage legumes, the potential interest of crop-livestock farmers in enhancing soil fertility restoration and dry-season feed supply was assessed during a socio-economic study on 11 farms of settled agro-pastoralists in the subhumid z...

Velvet bean (Mucuna pruriens (L.) DC. cv.-group utilis) is widely promoted in tropical and sub-tropical regions as a green manure cover crop that can reduce weed growth and soil erosion and enhance soil fertility. To provide these benefits, the crop must attain rapid ground cover and develop subs...

A programme of forage legumes evaluation was developed at ILCA subhumid research site in Nigeria from 1985 onwards. Evaluation included monitoring herbage and seed yields, incidence of diseases/pests, regeneration ability and persistence for three growing seasons. This was followed by an in six b...

The potential of 3-year-old grazed pastures of Stylosanthes hamata, Chamaecrista rotundifolia and Centrosema pascuorum to contribute to subsequent maize production was investigated in subhumid Nigeria in 1993. All three legume pastures had the ability to give better maize grain yields than native...
