| Summary: | Based on results of the research done during 2017–2019 on the sod-podzolic medium loamy soil of the Vologda region, when applying the estimated doses of fertilizers N90P40K100-120 we can achieve 67–79% increased yields of winter rye grains compared to the control. When applying fertilizers with the dose N12P16K16, yield of winter rye straw increases by 25%. With full estimated doses of fertilizer N90P40K100-120, straw yields increase by 74–87% compared to control. Uptake of nutrients of 1 ton of winter rye with respective amount of straw when applying estimated doses of fertilizers compared to control, increases by 4 kg for nitrogen, 3–4 kg for potassium and does not change for phosphorus. With N12P16K16, the "raw" protein is increased by 0.4% in absolute units or 3% in relative units compared to control, and with N90P40K100-120 –by 1.8–2.0% in absolute units or by 16-17% in relative units.
