Effect of Irrigation Scheduling and Different Sowing Dates on Water Productivity and Economics of Wheat (Triticum aestivum L.)

Abstract

“Effect of moisture regime under different sowing dates of wheat crop (Triticum aestivum L.)” was investigated at Acharya Narendra Deva University of Agriculture & Technology, Ayodhya (U.P.) Agronomy Research Farm in rabi season 2021-22. Twelve main plot treatments included 15th November, 25th November, and 5th December sowing dates, while four sub plot treatments included irrigation at 0.6, 0.8, 1.0, and 1.2 IW/CPE ratios. Split plot design was used for three replications. Under 15th November sowing, all growth, yield, and characteristics rose dramatically. Irrigation at 1.0 IW/CPE ratio increased wheat shoot m-2, plant height (cm), dry matter accumulation (g m-2), yield characteristics, grain and straw yield (q ha-1) considerably. D113 (15 November planting with irrigation at 1.0 IW/CPE ratio) had the best net return and D1I2 (15 November sowing with irrigation at 0.8 IW/CPE proportion) the highest B:C ratio (2.54). Wheat yields were highest when sown on November 15. Under 15th November planting, water use efficiency was highest (9.85 kg ha-1mm-1). Irrigation with 1.0 IW/CPE ratio had the maximum water usage efficiency (9.34 kg ha-1 mm-1). The 15 November seeding with irrigation at 1.0 IW/CPE ratio yielded the highest net return (1,17,124.00), making wheat farming profitable. Maximum B:C ratio (2.54) with I1D2 therapy.
