Abstract :Cowpea is one of the vital grain legumes used for human and animal nutrition. Due to its rich protein content, cowpea supplies the protein requirement, especially in the African continent. Although cowpea is morphologically similar to common bean, it is a more tolerant species to heat and drought conditions. So, cowpea production has various advantages in semi-arid regions. The aim of this study was to determine some agronomic traits of used cowpea genotypes and evaluate their correlations with yield components. Plant height insert ignore into journalissuearticles values(PH);, stem diameter insert ignore into journalissuearticles values(SD);, leaf surface temperature insert ignore into journalissuearticles values(LST);, total chlorophyll content insert ignore into journalissuearticles values(TCC);, number of pods per plant insert ignore into journalissuearticles values(NP);, number of seeds per plant insert ignore into journalissuearticles values(NS); and seed yield insert ignore into journalissuearticles values(SY); changed between 54.6-91.3 cm, 3.1-7.6 mm, 27.9-31.7 °C, 39-56.1%, 25.7-49.1, 307.5-684 and 646-2381 kg ha-, respectively. It is noteworthy that Karagöz produced the maximum SY compared to the other varieties. Besides, it was determined that SY has positive significant correlation with NS insert ignore into journalissuearticles values(r=0.98**);, NP insert ignore into journalissuearticles values(r=0.96**);, TCC insert ignore into journalissuearticles values(r=0.93**);, SD insert ignore into journalissuearticles values(r=0.91**); and PH insert ignore into journalissuearticles values(r=0.86**);.
