In the two rainy seasons, all the cowpea cultivars used effectively reduced the number of emerged S. asiatica plants m-2. The maize/cowpea intercrops also gave higher maize grain yields in the wet season (1996/97) but there were no differences in the dry season (1997/98), showing that their effects may depend on the type of the season. The use of any of these cowpea cultivars in a maize/cowpea intercropping system is recommended for smallholder (SH) sector where S. asiatica is a production constraint.Collection: CIMMYT Publications Collection
