| Summary: | AbstractTen early maturing cowpea genotypes were evaluated in three regions (Bako, Boneya Boshe, and Gute) of Western Ethiopia from 2019 to 2020. To determine the forage dry matter (DM), grain yield, and nutritional value attributes, the genotypes were evaluated and laid in a randomized complete block design with three replications. The findings revealed that ILRI-11114 outperformed other genotypes in terms of mean forage DM and crude protein (CP) yields across all sites and years, while ILRI-82D-504-4, ILRI-11990, and ILRI-12669 were higher in mean grain yields. In comparison to Boneya Boshe and Bako, the mean forage DM and CP yield received at the Gute location was greater. However, Bako produced more grains than Gute and Boneya Boshe did. The investigated fiber components did not differ significantly between genotypes (P > 0.05). The levels of CP, in-vitro organic matter digestibility (IVOMD), and metabolizable energy (ME) were higher in genotypes ILRI-11990 and ILRI-11114, while ILRI-12669 and ILRI-12732 had higher DM and ash values. The genotype ILRI-11114 was suggested for cultivation due to its greater forage DM, crude protein, and grain yield, as well as comparable CP, IVOMD, and ME levels. The performance of animals fed this genotype’s fodder should be evaluated in future research.
