The International Institute of Tropical Agriculture houses the largest collection of cowpea landraces in the world. This collection has been studied using agro morphological, botanical and geographic descriptors to define a core collection with a smaller reference collection being defined thereaf...

Optimal units of selection – how many plants are representative of diversity in collections of cowpea landrace accessions?
Common bean (Phaseolus vulgaris L.) is the most important food grain legume crop in west Usambara highlands, but its yield remains below the potential largely due to nutrient deficiencies in the soils. To identify nutrients limiting bean production, on-farm diagnostic trials were carried out at n...

After insects, mites are the major arthropod pests that inhabit stored agriculturalproducts worldwide. To determine the acarofauna that infests cowpea, maize, paddyrice and sorghum in Benin (West Africa), surveys were conducted in some principalmarkets (Dantokpa, Glazoue and Parakou) of this coun...

Putting agro-biodiversity to work: the cowpea story
Cowpea is traditionally important as an affordable source of protein and minerals and of cash income in sub-Saharan Africa, especially for small-scale farmers who have limited options for food and cash crops. The development and deployment of cowpea varieties with improved nutrition and quality t...

Soybean yields on smallholder farms in sub-Sahara Africa (SSA) are far below the potential yield thus creating a huge yield gap. Interventions are thus needed to bridge this yield gap and ascertain the factors influencing the yield variation. This study evaluated the on farm response of soybean t...
