A completely randomized factorial block experiment was carried out on spring 2006 in Eghlid agriculture research station to investigation the effect of different levels of phosphorus and potassium on the yield of prosper white bean line .The experimental variables included four levels of P2O5 (0, 23, 46 and 69 kg/ha)four levels of K2O ( 0,50, 75 and100 kg/ha).Phosphorus was used in the form of triple super phosphate and potassium in the form of potassium sulfate. The analysis of variance showed significantly different yield due to application of potassium and phosphorus. In the first year the highest yield (2595kg/ha) was obtained by application of 46 kg P2O5 /ha and 50kg K2O /ha, and the second year the highest yield (3900 kg/ha) was obtained from 46 kg P2O5/ha with 75 kg K2O /ha. According to 2 years of experiment, the highest yield resulted from 46 and 75 kg/ha and K2O respectively. As the results we concluded that the application of P and K increased seed yield and protein
