Response of Iron Nutrition on the Growth and Yield of Green Gram (Vigna radiata L.) in Semi-arid Region of Haryana

Background: A field experiment was conducted during the summer season of 2024 at the Crop Research Center of Kaliawash, SGT University, Gurugram (Haryana). Different level of iron sulphate were applied to green gram through basal and foliar application to study the effect of iron nutrition on growth and yield of the plant as well as soil nutrient availability. Methods: The experiment consisted of seven different treatments and three replications, in randomized block design. The soil of the experimental field was sandy loam in texture, slightly alkaline in reaction, had low levels of available N.P.K. Further lab analysis showed the deficiency of essential micronutrients like Zn, Fe, Cu and Mn. Result: The results specified that the highest growth parameters such as plant height (44.24 cm), number of branches per plant (15.98), number of trifoliate leaves (31.62) and yield parameters like number of pods per plant (16.48), number of grains per pod (9.67), test weight (36.00 g), grain yield (12.10 q ha-1) and stalk yield (34.98 q ha-1), were recorded under the treatment combination of RDF + foliar application (F.A.) of 0.6% FeSO4 at 30 and 45 DAS.
