Abstract

Intercropping is the traditional cropping system of the West African Sudan savannah with low system productivity. Timely growing together of adapted and compatible cowpea and maize cultivars is a potential way to improve the low productivity of the system. A two-year field experiment was conducted at Minjibir in Sudan savannah of Nigeria to determine the performance of medium and late maturing cowpea cultivars intercropped with extra-early and early maize cultivars at four and six weeks after maize. Early intercropping of cowpea with extra-early maize improved grain yield of cowpea (early maize, 405 kg ha-1 vs extra - early maize, 621 kg ha-1 ). Improved yield was also achieved with early intercropping of late maturing cowpea with maize (medium cowpea, 302 kg ha-1 vs late cowpea, 723 kg ha-1 ). Grain yield and crop value were maximized (884 kg ha-1 , $2411 ha-1 , respectively) with early intercropping of late maturing cowpea with extra-early maize. Therefore, late maturing cowpea can be recommended for intercropping with extra-early maize at four weeks after maize or less for maximum intercrop productivity.align='justify'>
