Abstract
The study titled âVarietal performance of wheat (Triticum aestivum L.) under different sowing datesâ was conducted during the rabi season of 2017-2018 at the Agronomy Farm, Shree Guru Ram Rai University, Dehradun, to evaluate the impact of varying sowing dates on the performance of three wheat varieties. A split-plot design was employed with three replications and fifteen treatment combinations, consisting of five sowing dates (1st November, 15th November, 29th November, 13th December, and 27th December) and three wheat varieties (HS-542, HD-2967, and HD-4728). Results revealed that the variety HS-542 was significantly superior in growth parameters, yield attributes, and yield compared to other varieties. The 15th November sowing date combined with HS-542 recorded the highest grain yield (44.33 q ha-¹) and straw yield (63.00 q ha-¹). The findings concluded that sowing wheat during the second fortnight of November, particularly using the variety HS-542, optimizes growth, grain and straw yields. This study highlights the importance of timely sowing and varietal selection to achieve higher productivity in wheat cultivation.
