Field comparative trial with common bean (Phaseolus vulgaris L.) and cowpea (Vigna unguiculata L.), was conducted at the Institute of plant genetic resources, Sadovo to identify the differences between two legume crops. Twenty genotypes from each crop were included in this study during 2022-2023. Agro-biological and morphological characterization on 20 quantitative and qualitative traits of common bean and cowpea were done. Different phenological phases were registered in each genotype. Common bean genotypes were sown during the first decade of April, while cowpea was sown in the last decade of the same month. Mass flowering began from 56 to 69 days after emergency, while in cowpea the same period began from 63 to 74 days. Vegetation cycle in two crops differed as the common bean plants matured for less number of days (average 87.3) compared with cowpea’s maturity, occurred after 97.4 days. Comparative study of yield components determining the plant yield, like number of pods per plant, weight of pods per plant, number of seeds per pod, weight of seeds per plant, yield per plant showed big differences. Number of pods per plant in common bean was with average of 8.0 numbers, while in cowpea the same character showed value of 11.1 pods per plant. Average weight of seeds per plant in common bean was 7.0 g while in cowpea the same trait was registered with 13.8 g. Weight of 100 seeds was 17.3 g in cowpea and 28.4 g in common bean.
