According to the results of a field experiment conducted on early-maturing winter wheat varieties Ultra, Asr Chilgisi, and Grat under four sowing dates (September 20, October 5, October 20, and November 5) and two sowing rates (4.5 and 5.5 million viable seeds per hectare), it was found that the Asr Chilgisi variety yielded the best results when sown on the second date (October 5) at a sowing rate of 5.5 million viable seeds per hectare. Under this treatment, higher field germination, overwintering, and plant density were observed compared to other sowing dates and rates.
