An application of calculated doses of fertilizer for potatoes in the gray forest soil of medium-size distribution, on average for 4 years, provided a receipt of planned crop of 25-35 tons per hectare and 94% of planned harvest in the background of 40 tons of tubers per hectare. Thus at higher fertilizer backgrounds, calculated to harvest 35-40 tons tubers per hectare, the starch content decreased and its harvest increased 2.22-2.33 times. The maximum permissible concentration of nitrate in potato tubers does not exceed.

Research was conducted to study the reaction of early varieties of Bellarosa potato to the application of calculated fertilizer doses and planting density in the conditions of the forest steppe of the Middle Volga region. Experiments were laid in 2012-2015 on gray forest soil of medium loamy granulometric composition, on the experimental field of the Transcaucasian Republic of Tatarstan. The article presents the results of 4 summer studies. It was established that the average yield for the 4 years was 41.17 tons per hectare, with a planting density of 66.6 thousand tubers against the background of nutrition, calculated to produce 40 tons per hectare. The introduction of calculated fertilizer doses for a potato yield of 30 tons per hectare, depending on the planting density, increased the productivity of tubers to 8.17-10.96 tons per hectare. The highest yield against this background – 31.18 tons per hectare on average for 4 years was formed at a density of planting 66,6 thousand pieces per hectare. It should be noted that the introduction of calculated fertilizers at this yield level increased the efficiency of increasing the density of planting, where the yield increase from this intake was 4.22 and 5.81 tons per hectare. The effectiveness of increasing the density of planting with a further increase in the background of nutrition was not so high. So, against the background of fertilizers calculated for yield of 35 tons per hectare, the increase from the increase in the density of planting to 60.6 and 66.6 thousand, compared to 55.5 thousand pieces per hectare, was 1.62 and 2.62 tons per hectare. Against the background, calculated for harvesting 40 tons per hectare on average over 4 years, an additional 1.60 and 2.90 tons per hectare of tubers were obtained.

The studies were carried out to determine the effectiveness of applying calculated doses of fertilizers to the planned potato tuber yields of the early-ripening Molly and Colette group in the conditions of the forest steppe of the middle Volga region. The influence of mineral nutrition backgrounds, calculated on obtaining tuber yields of 25, 35 and 45 tons per hectare in comparison with the unapproved control, has been studied. The analysis of the leaf area dynamics of potato plants, the parameters of the leaf photosynthetic potential, the coefficient of photosynthetically active radiation factor showed that these indicators of photosynthetic activity are directly dependent on the level of mineral nutrition. Against the background of natural fertility, the Molly variety produced 16.76 tons of tubers per hectare and 18.32 tons of the Colette variety. Fertilizers, calculated for 25-45 tons of tubers per hectare, ensured the formation of Molly 28.23-43.57 t ons per hectare, Colette - 29.72-42.54 tons per hectare. The introduction of calculated doses of fertilizers at 25 and 35 tons of tubers per hectare did not result in a significant decrease in the starch content in the tubers, and the doses that were calculated for a yield of 45 tons per hectare increased the amount of nitrates and reduced the starch content in the tubers.

In modern conditions, one of the priority directions of potato growing is the selection of new highly productive varieties, resistant to the action of abiotic and biotic factors. When potatoes are cultivated, the optimization of mineral nutrition and the depth of planting of seed tubers is an important factor for obtaining sustainable yields. The experiments were laid on gray forest medium loamy granulometric composition of the soil of the forest steppe of the middle Volga region. It was established that the highest yield - 52.50 tons per hectare was formed when fertilizer doses (manure 50 tons per hectare + N135-153P135-145K179-184) were calculated for 50 tons per hectare of tubers, when planting to a depth of 8-10 cm. On tte background fertilization in a dose of manure 50 tons per hectare + N120P120K140 when planting at the same depth yield was 49.50 tons per hectare. On the variant with a planting to a depth of 6-8 cm, the yield of tubers was to 2.89 and 2.92 tons per hectare lower.

Представлены результаты по изучению эффективности применения различных модификаций препарата МЕГАМИКС и комплексного минерального удобрения (нитроаммофоска) в технологии возделывании яровой пшеницы сорта Ульяновская 100 в условиях лесостепи Среднего Поволжья. Установлено, что под действием некорневой обработки препаратом МЕГАМИКС содержание белка в зерне повышалось на 0,67-1,03 % (неудобренный фон) и на 1,33-1,61 % (удобренный фон). В среднем за годы исследований, по сравнению с контрольным вариантом, повышение массовой доли клейковины составило 0,71-1,57 % (неудобренный фон) и 1,94-2,60 % (удобренный фон), в зависимости от варианта опыта. Применение препарата МЕГАМИКС и нитроаммофоски способствует снижению индекса деформации клейковины на 4,44-6,47 у.е., что, в свою очередь, улучшает технологические достоинства зерна пшеницы. Содержание крахмала в зерне опытной культуры увеличивается по сравнению с контролем на 1,81-4,99 %. Изучаемые модификации препарата МЕГАМИКС увеличивали урожайность на 0,37-1,43 ц/га на неудобренном фоне и на 1,41-3,12 ц/га на удобренном фоне. Наиболее эффективным по всем показателям является применение жидкого минерального удобрения МЕГАМИКС – ЦИНК на фоне комплексного минерального удобрения (нитроаммофоски). The results of studying the effectiveness of using various modifications of MEGAMIX and complex mineral fertilizer (ANP fertilizer) in the cultivation technology of spring wheat of the Ulyanovskaya 100 variety in the forest-steppe conditions of the Middle Volga region are presented. It was found that under the influence of foliar treatment with MEGAMIX, protein content in the grain increased by 0.67-1.03% (unfermented background) and by 1.33-1.61% (fertilized background). On average, over the years of research, in comparison with the control variant, the increase in the mass fraction of gluten was 0.71-1.57% (unfertilized background) and 1.94-2.60% (fertilized background), depending on the variant of the experiment. The use of MEGAMIX and ANP fertilizer helps to reduce gluten deformation index by 4.44-6.47 c.u., which, in turn, improves the technological advantages of wheat grain. The starch content in the grain of the experimental crop increases in comparison with the control by 1.81-4.99%. The studied modifications of MEGAMIX increased the yield by 0.37-1.43 c/ha against an unfertilized background and by 1.41-3.12 c/ha against a fertilized background. The most effective in all respects is the use of liquid mineral fertilizer MEGAMIX - ZINC against the background of a complex mineral fertilizer (ANP fertilizer).

The reaction of new early ripening potatoes of Molly, Red Scarlett and Kolette varieties on the main processing of gray forest soil in the conditions of the forest steppe of the Middle Volga region was studied. The aim of the work is to determine the effectiveness of different soil treatment options. The work was performed on the experimental field of Kazan SAU in 2012-2015. The dumping of plowing at a depth of 20-22 cm was compared with a non-spinning loosening of 26-28 cm and processing of a BDP by 18-20 cm. It was established in the course of research that, without spilling, Molly’s variety, on an average for four years, yielded 36.29 tons per hectare, with the dumping of plowing 35.89 tons per hectare. In similar variants, Red Scarlett formed the yields of 38.66 and 37.96 tons per hectare, and the grade of Kolette - 34.29 and 35.84 tons per hectare. With all methods of soil treatment, more starch contained potato tubers of the Kolette variety. Depending on the variant of soil cultivation, it was 13.73-14.13% in tubers of this variety. Less starch (12.83-13.20%) contained tubers of the Molly variety. Vitamin C and protein was more contained in the tubers of the Red Scarlett variety.

The aim of the research was to determine the optimal dose of phosphate fertilizers on the background of the use of nitrogen-potassium fertilizers in the potato cultivation of the middle-early group of Nevskiy variety. Experiments were carried out on gray forest soil of medium loamy granulometric composition with humus content in the arable layer according to Tyurin - 3.22-3.31%, easily hydrolyzed nitrogen - 140-155 mg/kg of soil, mobile phosphorus - 142-147 mg/kg, exchangeable potassium - 138-151 kg/kg of soil. Nitrogen-potassium background and sulfur in a dose of N90K120S30 were used in the experiments. Phosphate fertilizers were applied, depending on the variant, in increasing doses - P30, P60, P90, P120 kg of active substance. The results of studies on the effect of increasing doses of phosphate fertilizers on the productivity and quality of potato tubers of Nevskiy middle-aged group of ripeness are presented. Analysis of the content’s dynamics of the mobile phosphorus in the irrigated experimental plot of gray forest soil showed that it has a good provision with a mobile form of P2O5. During the growing season on fertilized variants, its content increased with increasing dose of phosphorus and varied in the soil phase of plant development. In the process of research, it was found that fertilizers in a dose of N90K120S30 (background) increased the crop of potato tubers by an average of 4 years by 9.54 tons per hectare. Phosphate fertilizers applied in addition to the background (N90K120S30) as their dose increases from 30 to 120 kg of active substance provided an increase in yield by 1.27-6.34 tons per hectare. The main elements of the mineral nutrition of plants in different ways influenced the quality of potato tubers. The introduction of phosphate fertilizers contributed to an increase in the content of dry matter, starch and improvement in taste in tubers, while the amount of nitrates decreased. Based on the data obtained, it can be concluded that in order to improve the quality indicators of tubers, a dose of fertilizers should be applied - N90P120 K120S30.

In 2019-2020, the quality of lawn-type grass mixtures based on creeping clover (Trifolium repens L.), meadow fescue (Festuca pratensis), pasture ryegrass (Lolium perenne) and meadow bluegrass (Poa pratensis) was evaluated in the conditions of the forest-steppe of the Middle Volga region (Penza region). The studied factors are the composition of the mixtures (creeping clover + bluegrass component), the seeding rates of the components (40 + 70 %; 55 + 55 %; 70 + 40 %) and the background of mineral nutrition (without fertilizers, P45K45, N30P45K45). The growing season during the years of research was characterized by arid conditions, the hydrothermal coefficient (HTC) for the period May-September in 2019 was 0.79, in 2020 - 0.76. On average, over two years of grass mixtures of creeping clover with meadow bluegrass at a seeding rate of 40 + 70 % and 70 + 40 % (from the seeding rate in pure form), creeping clover with meadow fescue with a seeding rate of 70 + 40 % components at all doses of mineral fertilizers had the highest comprehensive assessment of the quality of the lawn. The grass mixtures of creeping clover with meadow bluegrass (70 + 40 %) and creeping clover with meadow fescue (70 + 40 %) against the background of application of N30P45K45 had the maximum indicators in terms of herbage density (1425 and 1475 pcs/m2), which significantly exceeded the control and the variant with the introduction of Р45К45. In these variants, the highest indicators of projective cover (97.5 %) and a comprehensive assessment of "excellent" and "highest quality". According to weediness, the crops were estimated at 1 point (slightly weedy), per 1 m2 of annual and biennial weeds there were 24-27 pcs., rhizome weeds - less than 10 pcs. per 1 m2, the area of weed projective cover did not exceed 5 %.
