Type: article
Abstract: A field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (UP). The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice based on one-year of experimentation. The treatments consists of 3 different levels of phosphorus (40, 50, 60 kg/ha) and chelated zinc (0.5, 1g, 2 g/liter) as a foliar spray and a control. The results revealed that the application of 60 kg/ha P2O5 + 2 g/liter chelated zinc (EDTA) was recorded significantly higher plant height (36.80 cm), No. of Nodules/plant (117.5), Plant dry weight (26.06 g/plant), Number of pods per plant (37.6), Seeds/pod (2.37), Test weight (38.00 g), Seed yield pod yield (3.80 t/ha), Seed yield (2.74 t/ha), Haulm yield (4.87 t/ha), Harvest index (46.00%), Shelling percent (59.07%), Gross returns (Rs 89,600.00/ha), Net return (Rs 62,340.00/ha) and Benefit-cost ratio (2.28).
