Response of Foliar Spray of Iron and Gibberellic Acid on Growth and Yield of Greengram

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