An experiment was conducted at Bichpuri (Agra) during rabi seasons of 2006-07 and 2007-08 to study the impact of phosphorus and molybdenum on yield and nutrient uptake by broad bean (Vicia faba L) in alluvial soil. The experiment was laid out in randomized block design with four levels of phosphorus (0, 30, 60 and 90 kg P2O5 ha-1) and four levels of molybdenum (0, 1, 2 and 3 kg ha-1).The results revealed that the broad bean responded significantly up to 90 kg P2O5 ha-1 and increased the grain and straw yield by 13.4 and 15.7 percent, respectively, over control. Application of 3 kg Mo ha-1 proved superior to the control with respect to grain and straw yields and increased the grain and straw yields by 9.0 and 8.4 percent, respectively. The phosphorus levels significantly increased the nitrogen, phosphorus, potassium and molybdenum uptake by broad bean over control. Molybdenum application also influenced the utilization of nitrogen, P, K and Mo and the more beneficial effect was observed with highest level of molybdenum (3 kg ha-1).The status of nutrients in post harvest soil improved significantly with P and Mo levels over the control.
