This article describes the formation of seed yields and seed quality depending on the timing of sowing and seeding rates. On average, over three years, seed yields significantly decreased when sown at late sowing dates compared to the optimal date of September 25. The influence of the “sowing time” factor on seed yield was the largest and amounted to 86.6%, while the influence of the “seeding rate” factor was insignificant and amounted to only 4.3%. It was found that the germination energy and germination rate of seeds did not change significantly depending on the sowing date and seeding rate of winter wheat: when sown at the optimal time of September 25 with a seeding rate of 3 mln/ha, the germination energy was 96%, germination rate was 96%, and when sown later on October 5, these indicators were the same, and when sown on October 10, they were 92 and 95%, respectively. Depending on the seeding rates, the yield of winter wheat varied, but no significant difference was found within each sowing period. Seed quality ‒ germination energy and germination rate ‒ did not change significantly depending on the sowing date and seeding rate of winter wheat.
