The article analyzes experimental data on potato cultivation with the use of biologization elements in the conditions of the Ryazan region. were conducted two-year experiments for studying the effect of straw and siderate on the yield and quality of potato tubers of the variety “Red Scarlett”, cultivated on dark gray forest soils. Sideral fertilizer was represented by white mustard, sown to a depth of 4 cm with a norm of 5.5 million germinating seeds per hectare. When studying the “straw+nitrogen” variant, ammonium nitrate was introduced manually. In the case of the siderate using the plants were 2.2–19.6% higher, the number of stems on the bush and the leaf area were larger 4.8–13.3% and 4.8–25.1%, respectively, compared to the control sample. When using white mustard as a fertilizer, the number of weeds was 33.3–43.4 % lower compared to the control variant. Planting straw with nitrogen fertilizer provided an increasing of the mass of tubers in comparison with control samples in both years of research: by 2.9% in 2019 and by 8.1% in 2020. The yield of potato tubers of the variety “Red Scarlett” was increased by 11.4% when planting siderate, and by 10.8% when plowing straw.
