On the Quality of Bare-Grained Oats and Influence of its Cultivation Technology Elements on the Yie
The research was carried out with the aim to establish the formation regularity of both yield and its elements, as well as to formulate technological and quality indicators of bare-grained oats under the influence of different sowing periods. The studies were carried out in the conditions of the northern forest-steppe zone of the Kemerovo region (Russia) on the territory belonging to the Kemerovo Research Institute of Agriculture, a branch of the SFNCA RAS in 2018-2019. The soil of the site is leached chernozem, heavy loamy in granulometric composition, of medium thickness. The object of research was the mid-season variety of bare-grained oats Bare-grained. The predecessor is pure steam. Sowing was carried out in three periods: early – on May 4 (when the soil was physically ripe, subsequent ones with an interval of 8-10 days, depending on the prevailing weather conditions), medium - on May 12 and 14, late - on May 20 and 24. Against the background of each sowing period, the seeding rates of 4.0 were studied; 4.5; 5.0; 5.5; 6.0 million crops/ha. It has been established that the optimal sowing time for obtaining high quantitative indicators (yield, number of grains, grain size) of bare-grained oats in the northern forest-steppe of the Kemerovo region is an early period (first decade of May); while a later period (third decade of May) is more promising for such high-quality indicators as protein content, fat in grain, essential and nonessential amino acids, etc. The optimal seeding rate for bare-grained oats at early sowing period is 4.0-4.5 million/ha. At a later period, it is advisable to increase the seeding rate to 5.0-5.5 million/ha.
