Soybean can contribute to soil N, which may partly be used to improve maize production in northeast Nigeria. However, the efficiency of soybean to fix N can be limited by soil P deficiency. This study evaluated the effect of P application and soybean cultivars on dry matter and grain yield of sub...

Groundnut production in northeast Nigeria is constrained by low level of soil phosphorus. This study evaluated four groundnut varieties for their response to P fertilization in two Nigerian agro-ecological zones (Sudan and Northern Guinea savanna) during 2005 and 2006. The experimental design was...

Field studies were conducted in northeast Nigeria to evaluate the response ofearly and late-maturing maize varieties infested with natural populations ofStrigato different rates of nitrogen (N) fertilizer. There were significant reductions in thenumber of emergedStrigaat 120 kg N ha71for the earl...

The aim of this study was to assess the influence of farmers` crop management practices on Striga infestation and maize grain yield. Sixty farmers` fields were randomly selected in nine communities across three savanna zones. About 35% of the farmers had cultivated their fields for over 10 years,...
