Abstract
A field experiment was carried out at Agro meteorological Research Farm, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.) during rabi season of 2021-22 and 2022-23 to investigate the influence of different dates of sowing and varieties on wheat yield and yield attributes. The experiment comprised nine treatment combinations and conducted in split plot design and replicated four times. Treatment consisted of three dates of sowing viz. 15th November, 1st December and 15th December with three varieties viz, Wb2, K1317 and K9423. Among the varieties, Wb2 took relatively longer duration for maturity compared to K1317 and K9423. Results reveal that 15th November and Wb2 obtained higher values of effective tiller m-2, ear length, grains per ear, test weight followed by 1st December and minimum values were observed for crops sown on 15th December date of sowing during both year of experiment. There was significant variation observed in the grain yield, straw yield, biological yield and harvest index among the three distinct dates of sowing. The highest yield 43.9 and 42.7 q ha-1 were recorded under the 15th November, followed by 1st December (41 and 39.5 q ha-1) and minimum at 15th December (38.3 and 37.2 q ha-1) during both year of experiment respectively. Among the varieties, Wb2 has obtained the maximum values of yield 44.8 and 43.5 q ha-1 compared to K1317 (40.2 and 39.2 q ha-1) and K9423 (37.9 and 36.7 q ha-1) during 2021-2022 and 2022-2023, respectively.
