Weed infestation is one of the major factors attributed for the poor yield of cowpea in Nigeria and other parts of sub-Sahara Africa (SSA). Field trials were therefore conducted to evaluate the effect of row spacing and different weeding levels on weed control, growth and yield of cowpea during the early and late wet seasons of 2009. In both seasons, the use of 60 cm row spacing resulted in significant (
