Abstract: The most effective agricultural techniques in the production of high-quality and productive seeds of wheat varieties are the sowing time and seeding rate. The results of the study showed that the best time for new varieties of wheat in the conditions of 2019-2020. is sowing on May 25 with a seeding rate of 5.5 million viable grains per hectare. In terms of yield, the promising variety Beiskaya surpassed the zoned variety Krasnoyarskaya 12 in all variants by 0.1 - 0.3 t / ha. The response of varieties to seeding rates is more noticeable at a late sowing period: the difference in yield in thinned and thickened crops was 0.4 t / ha, while at an early date - 0.2 t / ha. Indicators of the parameters of the elements of the structure of yield (weight of 1000 grains, grain content of an ear, productive stalk) increased with a late sowing period. Analysis of variance of wheat varieties by yield revealed that this indicator significantly depended on the sowing time - 54%, seeding rates - 22%, as well as on the hereditary characteristics of the studied forms - 14%. The seed multiplication factor (the ratio of the mass of harvested seeds to the mass of sown seeds) was 20-22 at a seeding rate of 3.5 million germinating grains per hectare for both varieties and 12-14 at a seeding rate of 5.5 million germinating grains per hectare; the reduced seeding rate allows you to get an additional 4-6 tons of seeds.
