Striga hermonthica (L) Moench, a parasitic weed species, is a major constraint to sorghum production in the savanna zones of north-eastern Nigeria. The aim of this study was to assess the influence of farmer practices on Striga infestation of sorghum fields in the region. Random sampling techniqu...

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,...

The Guinea savannas of Nigeria have a high potential for the production of maize because of favorable environmental conditions. Despite this high potential, the yields obtained under farmers' conditions are still very low. Low soil fertility and intermittent drought are among major constraints li...
