The research was carried out on the experimental fields of the Federal State Budgetary Scientific Institution All-Russian Research Institute of Reclaimed Lands (FGBNU VNIIMZ) (Tver Region). Soil sod-podzolic light loamy and sandy loamy, drained, humus content 1.8-2.6%, medium and high content of nutrients, soil reaction weakly acidic and close to neutral. It has been established that when oats are grown in crop rotation after potatoes and winter rye, using the basic elements of intensive technologies, the oats sowing norms can be reduced from 6.0 million / ha of allotment grains recommended by the farming system to 4.0 and 5.0 without damage for the harvest. Analysis of the structure of the crop showed that a decrease in the norms of sowing of oats leads to a decrease in the density of standing of plants and the number of productive stems per unit area. The associated crop losses were compensated for by more intense plant growth and the increase in the mass of grain in the panicle. The associated crop losses were compensated for by more intense plant growth and the increase in the mass of grain in the panicle. With a decrease in the sowing norms from 8.0 to 3.0 million / ha of virgin grains, the number of productive stems consistently decreased from 506 to 309 pieces / m2, and the grain weight in the panicle increased from 0.77 to 1.22 grams, the number of grains in a panicle from 31.8 to 38.8 pcs., weight of 1000 grains from 24.1 to 31.4 grams. With a decrease in the oats sowing norms from 6.0 to 4.0 million, productive tillering of oat plants increased by 32.2%, grain weight in the panicle by 20.0%, the number of grains by 14.7% and weight of 1000 grains - by 4.9%. The decrease in the oats sowing norms from 6.0 to 4.0-5.0 million / ha of virgin grains reduces the consumption of seeds for growing 1 ton of grain by 16.7-33.4%, direct costs for cultivating oats per 1 hectare crops at the expense of saving seeds are reduced by 500-1000 rubles.
