To assess the genetic variability of the cowpea genotypes for yield, a field experiment was conducted at research field of National Grain Legumes Research Program (NGLRP), Khajura, Banke, Nepal during summer season of 2019. Twelve cowpea genotypes were evaluated in Randomized Complete Block Design (RCBD) with three replications. Analysis of variance indicated that all the genotypes were significantly different for an early stand, 50% flowering days, 90% maturity days, pods per plant, seeds per plant, final stand, 100 seed weight, grain yield except for plant height.
