The Field experiment was conducted during Kharif season, 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agricultural Sciences, Prayagraj, U.P, India. To evaluate the Response of Foliar spray of Iron and Gibberellic acid on the Growth and Yield of Greengram . The Soil of the experimented field was Sandy Loam in texture, slightly alkaline reaction (pH 7.0), low in organic carbon (0.40%), available N (161.48kg/ha), available 151.2kg/ha) and available K(232.5kg/ha).The Treatment consisted of FeSO4 (foliar spray at 15,30 DAS) 0.5%, 1.0% and 1.5% ,and GA3(foliar spray at 20,40 DAS) 50ppm, 100ppm, and 150ppm . The experiment was laid out in a randomized Block design and comprised of different levels of Iron and GA3 with ten treatments and replicated thrice. The growth attributes which was plant height (53.83cm), No. of Nodules/plant (51.00), Plant dry weight (11.67 g/plant) was significantly increased with increase in level of Iron and GA3.The Yield attributes was obtained Maximum, No. of Pods/Plant (24.5), No. of Seeds/Pod (12.00), Test weight (20.50g), Grain yield (1.95 t/ha), Stover Yield (3.15 t/ha) and Harvest Index (33.83%)at harvest. Maximum Gross Return (INR 1,29,112.50 INR/ha), Net Return (INR 92,803.50 INR/ha), highest B: C Ratio (2.56).
