The trial was conducted as a 3 partially confounded factorial experiment with two replications. Application of nitrogen phosphorus and potassium had profound influence on all growth characters like height of plant* number of functional leaves and branches per plant and leaf area index. The highest nodule count was obtained by the application of 15 kg N 25 kg Pg 5 and 20 kg KO per hectare while tho dry weight of nodules per plant was maximum at 15 kg N 50 kg 40 kg K2O per hectareennullThesis
