Cowpea as an intercrop under cereals

Wien, H.C., & Nangju, D. (1976). Cowpea as an intercrop under cereals. In Intercropping in semi-arid areas; Report of a symposium held at the Faculty of Agriculture. Forestry and Veterinary Science, University of Dar es Salaam, Morogoro, Tanzania, 10-12 May 1976, (p. 33).

One of the commonest systems involves grain legumes such as cowpea or groundnut planted under cereals such as sorghum, millet, or maize (31). Steele (32) suggests that cowpea may have come from its supposed center of origin, Ethiopia, to the West African semi-arid zone as part of such a cereal-legume farming system.
