Abstract
A field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice on the basis of one year experimentation. The results showed that application of PSB 20g/kg seed + 0.75% ZnSO4 was recorded significantly higher plant height (97.37 cm), Number of nodules/plant (112.60), Plant dry weight (18.41 g/plant), Pods/plant (31.2), Seeds/pod (2.20), Test weight (38.46 g), Pod yield (3.00 t/ha), Seed yield (2.46 t/ha), Haulm yield (4.94 t/ha), Harvest index (49.83%), Shelling percentage (82.13%), gross returns (Rs.98,508.00/ha), net return (Rs.71,388.00/ha) and benefit cost ratio (2.63).
