Nine cowpea (Vigna unguiculata (L.) Walp.) breeding lines were grown in 13 experiments under sole crop and intercrop management, with and without insecticide application, in Nigeria. Cowpea was intercropped with cassava (Manihot esculenta Cranz), maize (Zea mays L.) and maize-cassava in the fores...

Cowpea (Vigna unguiculata [L.] Walp.) is the most important grain legume in the dry savannas of West Africa, however grain and fodder yields are low (averaging 25 to 300 kg and 450 to 800 kg grain and fodder/ha, respectively) due to biotic and abiotic constraints. Improved varieties and cropping ...

Factors affecting cowpea growth in millet/cowpea intercropping were investigated in northern Nigeria. Ecological studies showed that cowpea received from < 30% to > 75% of incident light inside the intercropped canopy. In these light-limited conditions, cowpea varieties with a spreading growth ha...

Agrophysiological constarints in intercropped cowpea: an analysis
The imponance of cowpea (Vigna unguiculata [L.] Walp.) is underscored by its use as a component in many cropping system combinations in Africa, Asia, and tropical America. Cropping systems research over the past decade has served as a multidisciplinary approach to examine the biological superiori...
