Abstract

Cowpea (Vigna unguiculata L.) is an edible legume crop grown with multiple uses. Phosphorus (P) deficiency is particularly important in acid soils of South west Ethiopia affecting growth and yield of grain legumes particularly cowpea. Therefore, a field experiment was conducted to determine the response of cowpea varieties to P application on the soils of Dabo Hana District. The experiment consisted of Sewunet, Bole and Bekur cowpea cultivars and five P fertilizer rates (0, 23, 46, 69, and 92 kg P₂O₅ ha^-1). The experiment was laid out in a randomized complete block design in a factorial arrangement with three replicates. Data on growth and yield; P uptake parameters were collected and statistically analyzed using SAS version (9.3) software. The interaction effects of varieties and P rates significantly (p < 0.01) influenced different parameters. The highest grain yield (2582.89kg ha^-1) and straw yield (12,164 kg ha^-1) were obtained from the treatment combination of variety Sewunet and 69 kg P₂O₅ ha^-1. In conclusion, the study pointed out that cowpea varieties responded differently to the various P rates suggesting the possibility of exploiting varietal differences to combat P requirement of cultivars under acidic conditions. However, the present result based on one season and location may not lead us to make definite conclusion. As a result, it is recommended that the study should be repeated in more than one season and locations.
