The study was conducted with the objective to identify better adaptable, disease resistant, herbage and grain yield of cowpea accessions under Haro sabu ARC on station. The five cowpea accession adaptation tested included accession Cowpea12688, Cowpea17216, CowpeaIt82d889, Cowpea82d889 and Cowpea Ivu11421. Herbage dry matter and grain yield, and other agronomic data (50% flowering, disease incidence,) were measured to distinguish better adaptable accession. From the analysis result, there was statistical significance difference (p< 0.05) observed between treatments. From adapted cowpea accessions, CowpeaIt82d889 accession was better adaptable, coverage, resist disease and produced high herbage dry matter yield 10.56 ton/ha compared to the rest accessions Cowpea82d889 were followed. It is concluded that CowpeaIt82d889, Cowp82d889, were better performance accessions which are suitable for use as animal feeds.
