Common bean (Phaseolus vulgaris L.) is important pulse crop in Ethiopia.The low yield of common bean is party attributed to low phosphorus fertility of the soil.A field experiment was conducted at Hanaze village, Kindo Koysha district, Wolaita, Ethiopia, to determine grain yield and yield components and agronomic efficiency using factorial combinations of 4 P rates (0, 13.2, 26.4 and 39.6 kg haG 1 P) and 4 common bean varieties (Hawassa-Dume, Nasir, Omo-95 and Remeda) in randomized complete block design with 3 replications.With the increase in P rate from 0-39.6 kg haG 1 , seeds/pod increased from 3.27-3.77whereas days to flowering and maturity reduced from 57-52 and 76-73, respectively.The respective increase in pods/plant and grain yield (kg haG 1 ) with the increase in P rate from 0-39.6 kg haG 1 was from 2.40-17.00and 719-1542 for variety Hawassa-Dume, Nasir 2.60-9.47 and 583-1469, Omo-95 from 2.27-6.53 and 604-1062 and Remeda 2.20-9.47 and 312-1276.Agronomic efficiency declined from 92-21, 60-22, 42-12 and 32-24, for varieties Hawassa-Dume, Nasir, Omo-95 and Remeda, respectively, with the increase in P rate from 13.2-39.6kg haG 1 .The present experiment suggests that the soil P content would be assessed before fertilizer recommendation and variety Hawassa-Dume would be used in future to develop P efficient common bean varieties for P limited soils.
