ResumoField experiment was conducted during 2013 t o determine the response of common varieties to phosphorus fertilizer application. The treatment consists of three common bean varieties ( Hawassa Dume, Ibbado and Nasir) and three phosphorus rates (0, 20 and 40 kg P2O5 /ha) laid out in Randomized Complete Block Design with three replications. Data was collected on plant height (cm), number of nodule/plant, dry matter, number of pods/plant, number of seeds/pod, 1000 seed weight (g), seed yield (kg/ha), harvest index, crude protein content and phosphorus uptake. The increasing rates of fertilizer showed substantial improvement in nodule number, seed yield, crude protein content, fertilizer recovery, agronomic efficiency and physiological efficiency where the highest values of these parameters were obtained from fertilizer at the rate of 20 kg P2O5/ha. Hawasa dume showed the best performance in most parameters whereas Ibbado gave the lowest performance in contrary. These results can indicate the benefit of phosphorus fertilizer application and variety consideration for yield improvement, nodulation potential and better nutrient use efficiency of common in the study area.
