Effect of Irrigation Scheduling and Different Sowing Dates on Growth and Yield of Wheat (Triticum aestivum L.)

Abstract

The study was conducted at Acharya Narendra Deva University of Agriculture and 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. Irrigating 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. Wheat yields were highest when sown on November 15. Under 15th November planting, water use efficiency was highest (9.85 kg ha-1mm-1). Out of all treatments, 15th Nov planting had the highest biological (128.21 q ha-1) and seed yield (51.43 q ha-1) and irrigation on 1.0 IW/CPE had the highest biological (127.18 q ha-1) and seed yield (50.83 Maximum Harvest Index was 40.11 percent with 15th November planting and 1.0 IW/CPE ratio irrigation (39.96%).
