Cowpea is a key cash crop and also a staple food for millions of people in West and Central Africa. Cowpea trade is severely hampered by storage insects especially the cowpea weevil. The Purdue Improved Cowpea Storage (PICS) project was started in Nigeria in 2008 on a pilot basis in the states of...
Cowpea is a major food and cash crop in northern Nigeria, providing nutritious grain and a less expensive source of protein for both the rural poor and urban consumers. A number of improved varieties have been developed combining diverse plant type, and different maturity periods, with resistance...
A field study was conducted to determine the rate of genetic improvement in grain and fodder yields of cowpea genotypes developed in the Nigerian Sudan savannas from 1970 to 2004. Results showed that grain yield ranged from 568 kg/ha for an old variety TVX3236 to 1851 kg/ha for a recently release...
Plant architecture and N fertilizer may limit the performance of intercropped maize (Zea mays L.) and cowpea [Vigna unguiculata (L.) Walpers] cultivars. This paper describes an experiment in which cultivars of maize and cowpea were intercropped and fertilized with varying rates of N. The cowpea c...
Cowpea farming practices have been ongoing for millennia and have always faced various challenges including diseases, insects, and weeds, that lower its yield to no more than 200 kg/ha. This economically and nutritionally important crop has been a major research focus of the International Institu...
