“…A large role in increasing the yield and quality of tubers belongs to the variety and agricultural techniques of cultivation [2,3]. To obtain high yields and good quality tubers, they must be available to plants on time, in the required quantity and in the right form [4][5][6][7][8][9][10].…”

The features of the formation of productivity of potatoes of the Red Scarlett variety were studied during cultivation against the background of applying different combinations of organic, mineral, sideral fertilizers and straw in the conditions of the forest-steppe of the Middle Volga. The studies were carried out in the field experiment in 2014–2016 on gray forest soil with medium loam particle size distribution, on the experimental field of the Department of Plant Growing and Horticulture at KSAU. The humus content in the soil of the experimental plot was 3.48-3.65 % (according to Tyurin), labile phosphorus amounted to 128-135, exchange potassium amounted to 152–165 mg/kg of soil (according to Kirsanov), pH of the salt extract was 5.5-5.6. The experiments were performed on eight grounds with mineral nutrition. The potato yield in the reference ground due to natural fertility was 18.26 t/ha. Separate application of mineral fertilizers in a dose of N60P60K90 over an average of three years increased the tuber yield as compared to the reference of 10.19 ha, while the introduction of 60 t/ha of manure increased the yield by 8.95 t/ha. Using a traditional fertilizer system (N60P60K90 + 60 t of manure), the yield was 34.95 t/ha. As a result of the transition to the biological fertilizer system (background + green manure + straw), the yield increased to 36.26 t/ha, which is 1.31 t/ha higher compared to the traditional fertilizer system. On average, over 3 years, the maximum tuber yield of 37.48 t/ha was obtained by applying mineral and organic fertilizers, as well as straw. Sidereal fertilizers and straw provided an increase in the yield of tubers of 7.81 t/ha. The best results for the dry matter content (22.05 %) and starch (16.04 %) were demonstrated by tubers from the reference variant. More protein (2.95 %) and vitamin C (21.24 mg %) contained in tubers from the variant when mineral fertilizers were applied in a dose (N60P60K90-background) + green manure + straw.

The paper presents the results of predicting the yield of oats in the conditions of abandoned lands of the former pilot production farm (PPF) of the All-Russian Research Institute of Reclaimed Lands, located in the center of the Tver region. There were used the data of long-term monitoring (1997-2020) of the yield of this crop in clean and cover crops (with under-sowing of grasses) on the agroecological transect of the Gubino agroecopolygon located within the PPF. With the help of statistical and mathematical modeling, regularities in the formation of oat yields within the transect were revealed. On the basis of these formulas, predicted oat yields were calculated for the entire territory of abandoned lands, and maps of its variability under the conditions of the protected area and measures for intensifying grain production were also created. It has been established that oats in pure crops react most strongly to the content of exchangeable potassium in soils, to water supply and humus content, while in cover crops the yield largely depends on mobile phosphorus in the soil and the degree of illumination and swampiness of the territory. More than 92 % of the PPF area is potentially capable of providing oat yield in clean crops from 2.7 to 3.1 centners/ha, and an increased oat yield (3.0-3.3 centners/ha) in cover crops can be obtained only on ≈ 44 % of the farm area. The main methods for increasing the yield of oats in pure crops are the application of potash and organic fertilizers, as well as the preservation of moisture in the soil, while expanding the area of cover crops involves the use of oat varieties that react poorly to excess phosphorus in the soil. Intensification of oat production in clean crops is possible on the area of 6026 ha, and in cover crops only 790 ha, since in the rest of the territory its productivity is limited by insufficient illumination and waterlogged soils.
