Two field trials aimed to evaluate five introduced cowpea genotypes under three planting dates were conduced at the Agricultural Production Technology Station of Cairo University. Five cowpea (Vigna unguiculata, L (Walp) accessions i.e., IT 84 E-1-108, IT 83S-689, IT84-840, IT 83S-872 and IT 83S-880, were sown from Nigeria in May 15, May 30 and June 15 in two successive seasons (1993 and 1994). Results showed the optimum date for the cowpea accessions was May 15, as it gave the highest yield of dry pods, seeds, fresh, dry forage and crude protein. The best accession was the IT83S-689 in both seasons.
