The experiment was laid out as 3 partially confounded factorial experiment with two replications, confounding NPK in replication I and NPK2 in replication II Tho study revealed that nitrogen, phosphorus and potash had on influence on height and number of leaves, but not on nodulatlon. The yield contributing factors sanely number of flowers sad number of pods per plant, length of pod and number of seeds per pod ware not influenced by the treatments, Weight of seeds per plant was significantly increased by the highest level of potash and 100 seed weight by higher levels of phosphorus, while highest level of nitrogen significantly decreased tho 100 seed weight. Maximum grain yield of 538 kg/ha was obtained with the highest level of potash.Dry natter yield was also influenced by potash and bhusa yield by nitrogen.ennullThesis
