Maize (Zea mays L.) is an important staple food consumed by people with varying food preferences and socioeconomic backgrounds in West Africa (WA). Genotype by environment interactions (G×E) exist in WA implying the need for extensive testing of cultivars in multiple environments over years befor...

A field trial was conducted during the rainy seasons of 2008 and 2009 at Samaru in northern Guinea savannah of Nigeria to determine the performance of semi-determinate and indeterminate cowpea cultivars intercropped with extra early, early and late maize cultivars. The trial was laid out in a ran...

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...

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...
