The article presents the results of 2-year studies on the main agrotechnical methods for cultivating spring wheat polba in specific conditions. It is shown that the main agrotechnological method, that determines the productivity of a variety, is the introduction of calculated doses of mineral fertilizers, the depth of seeding. To a large extent, the productivity is associated with a combination of nutritional levels, optimal stalk density and depth of seeding. The most effective variants of cultivation technology are established. Changes in the formation of the density of stemstock are revealed with a change in the seeding rates, the depth of seeding at both feeding levels.
