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%).
