Effect of Nitrogen and Sulphur on Yield and Economics of Wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted during Rabi 2021-20222 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out on Randomized Block Design with nine treatments each replicated thrice on the basis of one year experimentation. Variety of wheat DBW-187, Furrow Irrigated Raised Bed technique for irrigation. The treatments which are T1: Nitrogen 80 kg/ha,+ Sulphur 15 kg/ha, T2: Nitrogen 80 kg/ha + Sulphur 30 kg/ha, T3: Nitrogen 80 kg/ha + Sulphur 45 kg/ha, T4: Nitrogen 100 kg/ha + Sulphur 15 kg/ha, T5: Nitrogen 100 kg/ha + Sulphur 30 kg/ha, T6: Nitrogen 100 kg/ha + Sulphur 45 kg/ha, T7: Nitrogen 120 kg/ha + Sulphur 15 kg/ha, T8: Nitrogen 120 kg/ha + Sulphur 30 kg/ha, T9: Nitrogen 120 kg/ha + Sulphur 45 kg/ha are used. The results showed that application of Nitrogen 120 kg/ha + Sulphur 45 kg/ha was recorded significantly maximum No. of Grains/spike (47.34), Test weight (38.30 g), Grain yield (6.14 t/ha), Straw yield (9.52 t/ha), gross returns (Rs.99911.66/ha), net return (Rs.67591.73/ha) and benefit cost ratio (2.09) was obtained as compared to other treatments.
