Description
Summary:This paper presents the findings of long-term field experiments to study the influence of increasing doses of mineral fertilizers on the technological and agrochemical features of Siberian-bred oat. The studies were performed in the forest-steppe zone of the Trans-Urals on leached chernozem. We have studied the varieties of cultivated oat of local selection: Talisman, Foma and Otrada on a natural soil preparation (control) and while applying fertilizers, in doses calculated to obtain the planned yield from 3.0 to 6.0 t/ha. It has been revealed that modern varieties of oat have genetic features for the assimilation of nutrients from the soil and fertilizers. It affects the content of protein, fat and starch in the grain. Accounting for the totality of indicators of the chemical composition, the Foma variety was distinguished. Its grain on fertilized variants contains: protein 10.8-15.3; fat - 3.0-3.6; starch - 33.0-45.7%. The use of mineral fertilizers results in an increase in the nitrogen content in grain and straw, and potassium - only in straw. The biological removal of nutrients depended on the level of mineral nutrition and the variety, giving ground for the development of a varietal system of fertilizers for oat in Western Siberia.
