Field trials were conducted in 2005 and 2006 in Tilla (northern Guinea savanna) and Sabon-Gari (Sudan savanna) in northeast Nigeria to determine the performance of two improved cowpea varieties when relay-intercropped with early and late maize, 6 and 8 weeks after planting the maize. Grain yield,...

Performance of semideterminate and indeterminate cowpeas relaycropped into maize in Northeast Nigeria
Cowpea-maize intercropping causes low yields of cowpea due to shading effect by maize plants. Staggering of dates of planting of cowpea in an intercrop is a potential way of reducing intercrop shading while increasing cowpea yield. Nonetheless, contrasting cowpea cultivars may have differential r...

Agronomic responses of diverse cowpea cultivars to planting date and cropping system
Maize cultivation has recently expanded to the West African Sudan savannah and has the potential to play a key role
in the cropping systems of the region where intercrop yields have been low. Staggering planting date and
manipulating plant population of component crops are potential ways to impro...

The morphological and phenological variations in 46 accessions of Lablab purpureus were evaluated in 2000 and 2001 in Samaru, Zaria in the moist savanna zone of Nigeria. Accessions were classified into various groups according to plant structure, flowering time and pod and seed characters. Based ...
