Abstract

The experiment was laid out in Randomized Block Design with nine treatments each replicated thrice on the basis of one year of experimentation. The treatments which are T1: 2% Sulphur+0.5% zinc, T2: 2% Sulphur+ 1% Zinc, T3: 2% Sulphur + 1.5% Zinc, T4: 3% Sulphur + 0.5% Zinc, T5: 3% Sulphur +1% Zinc, T6: 3% Sulphur +1.5% Zinc, T7: 4% Sulphur + 0.5% Zinc, T8: 4% Sulphur+ 1% Zinc, T9: 4% Sulphur +1.5% Zinc, T10 N:P: K 20:40:40 kg/ha. The results showed that application of 4% Sulphur+ 1.5% Zinc was recorded significantly higher plant height (79.17 cm), nodules/ plant (30.93), Plant dry weight (22.83 g/plant), No. of pods/ plant (12.14), Test weight (100.23 g), maximum crop growth rate (8.82g/m2/day). However, higher Seed yield (1.32 t/ha), Stover Yield (3.48 t/ha) gross returns (INR84971.50/ha), net return (INR60594.40/ha) and benefit cost ratio (1.28) were obtained with application of 4% Sulphur+1.5% Zinc as compared to other treatments.
