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.

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 work aims to study the effectiveness of herbicides application on potato varieties of different ripeness groups in the conditions northern forest-steppe of the Novosibirsk Ob region. The authors obtained experimental data on leached chernozem in Novosibirsk district, Novosibirsk region, in 2017-2019. In their studies, the authors used common elements of potato cultivation tech- nology. The general background for potatoes in autumn fertiliser was applied at a dose of P60K90. Nitrogen fertilisers were used at a rate of 60 kg/ha in spring under pre-sowing cultivation. Herbicides Gezagard, Lazurit, Zenkor, Boxer, and mixtures of individual herbicides were applied before and after sprouting when potato plants were up to 12-14 cm high. Herbicides significantly reduced the infestation of potato varieties Lubava (early) and Tuleevsky (medium-season). The authors showed that the use of herbicides accelerated the processes of growth and development of potato varieties of two groups of ripeness. There was a significant increase in leaf area, photosynthetic potential, and 23-28% plant productivity. On a background of herbicides increase of yield by 30-35% is observed. There was an increase in the marketability of tubers by 10%. Used herbicides provided good quality and preservation of potato production. The authors note that the double application of herbicides Zenkor and Lazurit offers high rates of weed reduction. Thus yield and quality of presentation have high indicators. In tubers of potatoes, the residual quantity of herbicides is not detected. Application of herbicides economically and energetically practical. The level of profitability exceeds control 1,4 times on a background of double spraying by herbicides Zenkor and Lazurit.

The article discusses the features of the formation of the leaf surface, photosynthetic potential and yield of tubers, depending on the timing and density of potato planting. The objective of our research was to study photosynthetic activity, yield and quality of potato tubers depending on the density and timing of planting. Field experiments were carried out in the forest-steppe zone of the Trans-Urals in 2014-2017 with potato varieties Rosara (early ripening) and Kuzovok (mid-ripening). The optimal combination of agricultural practices has been established to obtain the planned potato yields with high quality tubers - planting on May 12-15 (Kuzovok varieties according to the scheme 75x27 and 75x19 cm, and Rosara varieties - only 75x19 cm). The optimal planting period provides the greatest photosynthetic potential of potatoes with a thickened planting scheme (4.18-5.45 million m2/ha-days), which, due to the assimilation of 3.9 to 4.4% of photosynthetically active solar radiation, ensures the formation of a crop of tubers 40.2-42.8 t/ha. The fourth term for planting potatoes (June 5-12), reducing the FP by 12.6-21.9% depending on the variety, the PAR efficiency - by 28.4-30.1%, caused a decrease in yield by 6.6-7, 4 t/ha, tuber starch content - by 2.0-2.7% compared to planting on May 12-15. At the same time, the amount of nitrates in tubers increased by 1.93-2.22 times.

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.

Introduction of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea to early ripe potatoes of Zhukovsky and Red Scarlett variety on the planned productivity of 40 t/hectare has allowed to achieve a goal. At the same time in control option without fertilizers the productivity was 23,2-24,8 t/hectare. Use of encapsulated urea has led to decrease in productivity and level of profitability by 26,3-30,9%. Early ripe potatoes of Zhukovsky and Red Scarlett variety on natural fertility of the chernozem leached in the northern forest-steppe of the Tyumen region have created average yield of 23,2-24,8 t/hectare for years of researches. Use of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea on the planned productivity of 40 t/hectare has led to increase in productivity on the first variety to 39,5 on the second variety up to 41,4 t/hectare. Introduction of the encapsulated urea has led to decrease in productivity of the early ripe potato tubers studied. At the same time, the peel was gentle and when cleaning it was strongly injured. As to the content of starch (11,9-12,6%) at both varieties the big difference between ex-perience options isn't revealed. The similar picture was observed also according to tastes of tubers. It has made 3,2-3,5 points at Zhukovsky variety and 3,4-3,7 points at Red Scarlett's variety. Profitability level in con-trol option at Zhukovsky variety was 157,3%, at Red Scarlett's variety – 140,5%. In options with non-encapsulated ammonium nitrate and urea the first variety got 172,6-184,1%, second variety – 190,4-207,2%. In option with encapsulated urea at varieties under study the profitability level has decreased 26,3-30,9.

Purpose. The aim of the research conducted during 2016-2019 was to determine the impact of technological methods on the indicators of corn grain quality to optimize the elements of growing technology depending on the directions of use in conditions of the Forest-Steppe natural zone of Ukraine. Methods – field, quantitative and weight, chemical, comparative and calculation, mathematical and statistical. Results. On the results of the research, dependences of formation of quality of grain on the content of protein, starch, fat in it and correlation dependencies between these indicators and yield of corn have been revealed. The best quality of grain of a forage and food direction is formed when applying high doses of mineral fertilizers, and for processing on bioethanol the optimal content of starch and protein is guaranteed at optimum and raised level of fertilizing. It was established that the content of protein, starch and fat had less effect on their yield from 1 hectare than the general yield level. The technologies of cultivation of different intensity as to their possible application for the production of grain of different directions of use with the given quality parameters, the yield of protein, starch, fat and bioethanol have been evaluated. Conclusions. The technology of corn growing with complex application of intensification elements in conditions of the Forest-Steppe zone, which includes introduction of N240P120K240 on the background of by-products of its predecessor, application of the soil and insurance herbicide, plant growth and micro-fertilizers is suitable for fodder and food purposes and ensured the yield of 12.1 t/ha of grain with protein content and yield – 10.56% and 1.28 t/ha, fat – 4.29% and 0.52 t/ha, starch – 71.27% and 8.62 t/ha. For processing on bioethanol effective is the technology of corn growing with the introduction of N180P120K180, by-products of the predecessor, soil herbicide and bio-stimulants, which provided a yield of 9.76 t/ha of grain with a starch content of 72.26% for the yield of 7.05 t/ha and yield of bioethanol at the level of 3982 l/ha.

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.

Experimental studies have shown that with an increased level of mineral nutrition (N120P180K240) all varieties increased the yield (by 1.7–4.1 tons/ha, or by 10–25%), while the most productive varieties being Bryansky Nadezhny, Bryanskaya Novinka, Slava Bryanshchiny (21.9–22.9 tons/ha). In terms of dry substances content almost all varieties met the requirements of processing, which called for for a dry substance level in tubers of at least 20–24%. With an increase in the dose of fertilizers the amount of starch and dry matter in tubers decreased. On an average background, the starch content compared to the control decreased by 0.7–1.1%, dry substances — by 0.7– 1.2%, on an increased background respectively — by 1.2–1.7%, dry substances — by 1.4–2.7%. The taste of potatoes on an increased background of fertilizers worsened regardless of variety. In terms of darkening of the flesh, raw cleaned tubers of all varieties are not suitable for long-term storage (for example, for 24 hours), while boiled tubers of all varieties did not reduce the quality. Growing potatoes on an increased background of mineral nutrition increased the darkening of raw tubers of the studied varieties compared to control. In the studied varieties the content of reducing sugars in many cases exceeded the amount allowed for the manufacture of crispy potatoes, and therefore its quality was reduced, mainly due to the color of the slices. Almost all varieties gave puree of good quality. An increase in the background of fertilizers slightly worsened the consistency of puree, which reduced the overall estimate.
