The parasitic flowering plants Striga gesnerioides (Willd.) Vatke and Alectra vogelii (Benth.) are formidable cowpea production constraints in the West and Central African savanna. The two parasites cause substantial yield reduction in cowpea in the dry savannas. A field study was conducted to sc...

The interactions between the cowpea aphid Aphis craccivora Koch, its parasitoid Lysiphlebus testaceipes Cresson and hyperparasitoid Syrphophagus africanus Gahan were assessed in the laboratory. Host age preference for hyperparasitism was evaluated using parasitized aphids of different ages (i.e. ...

High seed quality is a critical component for realising yield potential. For smallholder cowpea farmers in northern Nigeria the informal seed system is a major supplier of genetically high-quality seed, but the physiological quality of farmers’ produced seed remains unknown. The project “Promotin...

The incidence of the key insect pest of cowpea (Vigna unguiculata L. Walp), the legume pod borer Maruca vitrata F., was investigated with light trap in the Sudano-Sahelian zone of Niger in 2014 and 2015. The results revealed that the first larvae appeared in August (0.03 ± 0.03 to 2.48 ± 0.32 lar...

Herbaceous legumes are becoming increasingly important for the crop-livestock farming systems in the moist and semi-arid regions of West Africa as these crops cover the ground quickly, check erosion, contribute to soil fertility and provide nutritious food and fodder to human beings and livestock...

Crop response, tree biomass production and changes in soil fertility characteristics were monitored in a long-term (1986–2002) alley-cropping trial in Ibadan, Nigeria. The systems included two alley cropping systems with Leucaena leucocephala and Senna siamea on the one hand and a control (no-tre...

Studies were conducted on the population fluctuations of the cowpea pod weevil, Piezotrachelus varius on cowpea at Melong, NY(lkon and Babessi, and the susceptibility of seeds of selected cowpea cultivars to its damage in the western derived savanna zone of Cameroon, during the 1999 and 2000 cowp...

Cowpea [Vigna unguiculata (L.) Walp.] is a major tropical legume crop grown in warm to hot areas throughout the world and especially important to the people of sub-Saharan Africa where the crop was domesticated. To date, relatively little is understood about its domestication origins and patterns...
