Effect Of Different Sowing Dates And Varieties Of Wheat (Triticum Aestivum L.) Crop Grown Under Agro-Climatic Conditions Of Eastern Uttar Pradesh

Abstract

A field experiment was carried out at Agrometeorological 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 date of sowing and varieties on wheat growth parameters, including phenophases occurrence, leaf area index (LAI), plant height, and dry matter accumulation at various stages of crop development. The experiment comprised nine treatment combinations and conducted in split plot design and replicated four times. Treatment consisted of three date of sowing viz.15^th November,1^st December and 15^th December with three varieties viz, Wb2, K1317 and K9423. Results reveal that Plant height (cm), dry matter accumulation (gm^-2) and leaf area index increased significantly at all the stages of crop growth. Highest values are recorded with the crop sowing on 15^th November followed by 1^st December. Lowest values of all were recorded in 15^th December date of sowing. Among the varieties, Wb2 took relatively longer duration for maturity compared to K1317 and K9423. These findings underscore the importance of carefully managing both dates of sowing and varieties to optimize wheat growth and development. This research contributes to the broader understanding of crop responses to date of sowing and provides valuable insights for selection of variety strategies aimed at improving crop yield and resilience in the face of changing climate conditions.
