Morphological Characters, Dry Matter Production, and Nutritional Quality of Cowpea (Vigna unguiculata L.) as Influenced by Genotype and Environment

Cowpea is an important grain legume crop used as feed for livestock, and its dry beans provide protein. Consequently, the objective of this study was to evaluate selected cowpea genotypes herbage matter yield nutritional quality in two agro-ecologies Benishangul-Gumuz region. The conducted at Kamashi Assosa forages research stations Agricultural Research Center, sites were purposively represent lowland midland agro-ecologies, respectively. Four cowpeas’ accessions (V. Unguiculata ILRI-11114, ILRI-12688, ILRI-12713, ILRI-9333) one check (Melka (ILRI-9334) a check) evaluated randomized complete block design with three replications. Herbage yield, plant height forage harvesting, days maturity significantly affected by location (L). Longer heights, shorter maturity, higher ( P < 0.001 ) recorded than Assosa. id="M2"> 0.05 year (Y), Y id="M3"> ∗ L (Y interaction), G id="M4"> id="M5"> (genotype (G), id="M6"> L.

However, neutral fibre id="M9"> influenced genotype. Thus, from present study, it can be recommended that ILRI-12688 are suitable ILRI-11114 areas terms biomass production.
