Field trials were conducted from 2001 to 2004 at the research farm of the Michael Okpara University of Agriculture, Umudike, South Eastern Nigeria to evaluate the yield and its components in nine vegetable cowpea cultivars. The cultivars differed significantly in yield and most of the components and the yield were not stable across the years of the study though, few cultivars seem to have stable yields. Pod yield was positively correlated with number of pods/m2, pod length and width and these attributes could serve as selection indices for this crop.


Key words: Vegetable cowpea, yield, yield components.
