Response of Sulphur and Zinc on Yield and Economics of Maize (Zea mays L.)

Abstract

The field trial was conducted during the 2022 Rabi season at the Crop Research Farm of the Department of Agronomy, Nain Institute of Agriculture, Sam Higginbottom University of Agriculture, Technology and Science, Prayagraj (U.P.), India. To study the effect of sulphur and zinc on the yield and economics of Rabi maize. The treatment includes sulphur 20, 30, 40 kg/ha and zinc 15, 20, 25 kg/ha. The soil of the experimental area had a sandy clay texture, almost neutral soil reaction (pH 7.8), low organic carbon (0.35%), nitrogen (163.42 kg/ha), phosphorus (21.96 kg/ha) and potassium (21.96). kg/ha). 256.48 kg/ha). Sulphur 40 kg/ha Zinc 25 kg/ha significantly increased yield characteristics and economy. The results showed that higher grain yield (6.42 t/ha) and higher stover yield (14.36 t/ha) were significantly influenced with application of sulphur 40 kg/ha Zinc 25 kg/ha. Higher gross returns (INR 1,30,268.40/ha), net returns (INR 90,007.00/ha) and maximum benefit cost ratio (2.23) were recorded in treatment-9 with application of (Sulphur 40 kg/ha Zinc 25 kg/ha).
