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

Abstract

A field experiment was conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of the 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 based on one year experimentation. 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 to significantly higher Plant height (98.13 cm), No. of Tillers/hill (10.71), Plant dry weight (17.83 g/plant), whereas significantly highest Crop growth rate (7.47 g/m2/day) was recorded with the treatment Nitrogen 80 kg/ha + Sulphur 15 kg/ha. However, significantly maximum No. of Grains/spike (47.34), Test weight (38.30 g), Grain yield (6.14 t/ha), and Straw yield (9.52 t/ha) was obtained in the treatment of Nitrogen 120 kg/ha + Sulphur 45 kg/ha as compared to other treatments.
