Abstract: Faba bean (Vicia faba L.) is a multi-purpose crop owing to its immense economic and ecological benefits. Genetic variability assessment for agronomic traits is a crucial step in improving the yield and yield components of the crop. Phosphorus deficiency seriously affects the yield of faba bean. The present study was conducted to evaluate the genotypic variability of faba bean for agronomic traits. Twenty and 12 genotypes, in the field and greenhouse respectively, were planted under two P fertilizer regimes (0 and 46kg/ha). Analysis of variance indicated highly significant (P<0.01) genotypic variation for most of the agronomic traits under both field and greenhouse; while grain yield (GY), days to fifty percent flowering (DFF), number of pods per plant (NPP) and days to 90% maturity (DNM) had significant genotype by location interaction. The agronomic performance of P-unfertilized (P-) treatments was significantly reduced; with the effect ranging from -4.6% for DNM to 20.3% for NPP in the field; and from -3.6% for DFF to 21.6% for shoot dry weight per plant (SDWP) in the greenhouse. Correlation analysis indicated that most traits were strongly correlated to one another; with consistently significant correlation among GY, DFF, and NPP. Biomass production per day (BPD), GY, SDWP, DNM, and NPP were the highest contributors to the genetic variation. Mean comparisons and biplot analysis results revealed that genotypes Moti, Gebelcho, Dosha, Tumsa, and Didea had superior agronomic performance under all conditions. The study revealed the availability of genotypic variation among the faba bean genotypes for agronomic traits.
