The article presents the results of research conducted in different soil and climatic conditions of the Middle Volga region on the influence of regulated factors, as well as environmental factors on the production process of plants of various types of spring wheat. The amount of photosynthetically active radiation (PAR) is enough to obtain yields within 12–13 tons of dry biomass or 6–7 tons of grain. Natural precipitation is able to provide 3.82–4.36 t of spring wheat grain from 1 ha, and 4.5–6.3 t/ha by the total influence of solar energy, heat and moisture supply. Natural level of soil fertility without application of organic and mineral fertilizers allows to receive about 2 tons of spring wheat grain from 1 ha. Application of nitrogen in the form of ammoniac water (N-20.5 %) increased the yield in comparison with the use of nitrogen in the form of ammoniac saltpeter: the increase was 0.14 t per 1 ha. In the conditions of grey forest soil in the Predkamye region of the Republic of Tatarstan the optimal norm of sowing of spring wheat Triticum dicoccum Schuebl (spelt) depending on the feeding background was established. Growth of yield at sowing of 6 million seeds per hectare at all levels of nutrition in comparison with sowing rate of 4 million tons per hectare was 0.18 tons per hectare against the natural background, against the estimated background of NRC on 2.0 tons of grain – 0.19 tons and 2.5 tons of grain – 0.24 tons per hectare. The maximum yield increase was received at a combination of a mineral foodstuff with an optimum norm of sowing and has made on a settlement background 2 tons of grain from hectare – 0.20 tons, on 2.5 tons of grain – 0.34 tons from hectare. Thus, the aim of our research was to develop methods of growing high yielding quality grain of different types of wheat adapted to the conditions of forest-steppe in the Volga region.

The article considers the results of observation of the growth, development and formation of winter wheat grain yield depending on the methods of basic soil treatment, applied fertilizers and biofungicide  Phytotrix. It was found out that the options with shallow and surface treatment were not inferior to the control in terms of yield (plowing by 20-22cm). Mineral fertilizers in a dose of N30P30K30 provided an increase in the productivity of winter wheat relative to the non-fertilized background by an average of 0.54 t / ha. Treatment of plants with phytotrix increased grain production on a non-fertilized background by 0.33 t / ha, on the background of N30P30K30 by 0.76 t / ha. The maximum yield of winter wheat-5.03 t / ha was achieved with the use of combing on the background of N30P30K30 + Phytotrix. The greatest responsiveness in collecting grain from fertilizers was observed in the variants of comb-back processing and surface disking, where the increase was 0.68-0.89 t / ha against the background of N30P30K30 application, and 1.05 t/ha against the background of N30P30K30 + Phytotrix relative to the natural background of the corresponding treatments.Apply mineral fertilizers in a dose of N30P30K30, with the application of biofungicide treatment on the vegetation of the crop, which will increase the yield by 0.76 t / ha, compared to the non-fertilized background.

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 %.

The article presents the data of assessing the productivity and nutritional value of selection samples of creeping clover in the nursery of the competitive variety testing of 2016 sowing for three years of use. The purpose of the research is to identify a promising breeding material of creeping clover for creating a variety with high productivity of green mass and seeds, suitable for mechanized harvesting of seeds for the conditions of the forest-steppe of the Middle Volga region. The research was carried out in 2017-2019 on the experimental field of a separate subdivision of Penza FGBSI FSC of BC in accordance with the methodological instructions for the selection of perennial grasses. On average over three years of use in terms of the yield of green mass – 15.00-16.44 t/ha, cultivar samples of creeping clover V-92, Yu-90, P-97, Pl-90-4 significantly exceeded the VIK-70 standard (14,01 t/ha) by 7.1-17.3%, for the collection of dry matter – 3.49-3.97 t/ha varieties V-92, Yu-90, P-97 and Pl-90-3 reliably exceeded the standard (3.29 t/ha) by 6.1-20.7%, in the collection of digestible protein – 0.44-0.49 t/ha, the varieties B-92 and P-97 exceeded the standard (0, 40 t/ha) by 10.0-22.5%. Maximum values of the yield of green mass (16.44 t/ha), dry matter collection (3.97 t/ha), digestible protein (0.49 t/ha), feed units (5.04 t/ha) and exchange energy (49.12 GJ/ha) on average for the years of testing showed the sample P-97. This specimen significantly exceeded the standard in terms of structural elements and seed yield by 50.5%, in the height of leaf petioles by 3.5% and peduncles by 2.5%, which is important for mechanized harvesting of seeds. When selecting for the productivity of creeping clover, one should pay attention to the signs associated with the yield of green mass and seeds. The length of leaf petioles correlates with the length of peduncles (r = 0.78), the number of seeds in the head (r = 0.46), the number of inflorescences in the head (r = 0.47), with the collection of dry matter (r = 0.31). The length of the peduncles correlates with the collection of dry matter (r = 0.30), with the number of inflorescences in the head (r = 0.54), and with the number of seeds in the head (r = 0.51). The number of inflorescences in the head correlates with the number of seeds in the head (r = 0.61) and with the yield of seeds (r = 0.31)

The complex effect of pre-sowing treatment of seeds with a protectant and liquid mineral fertilizer with subsequent foliar feeding on the growth processes and the formation of elements of productivity of hemp in the conditions of the forest-steppe of the Middle Volga region was studied. Studies have established that treatment of seeds before sowing by fungicide TMTD, VSC at the dose rate of 2.5-5.0 l/t provided the safety of the plant to harvest to 88,0-89,8 %, fertilizer Isagri Force at a rate of 1.0 l/t -- of 90.2 %. The positive influence of the investigated factors on yield structure elements: the length of inflorescence increased with the use of drugs TMTD, VSC and Isagri Force to study the consumption rates of 22.9 and 37.1 %, adding foliar treatment by 20,0% compared with the control without treatments. A significant increase in the diameter of the stem was observed when processing seeds with TMTD, VSK and Izagri Force in the consumption rates of 2.5 and 1.0 l / t by 9.5 % compared to the control. The increase in the number of internodes was promoted by treatment with drugs TMTD, VSC at a rate of 5.0 l/t and Isagri Force in doses of 1.0 and 0.5 l/t in comparison with control without treatments. Pre-sowing treatment with Izagri Force fertilizer in the consumption rates of 0.5-1.0 l / t increased the yield of seeds by 4.3 – 7.5 %. A statistically significant increase in this indicator relative to the control variant was found in the variants with Izagri Phosphorus treatment for vegetation (+0.17 t/ha or 13.6 %). The most responsive hemp plants were on the interaction of the mordant, fertilizer and foliar feeding of plants during vegetation, the increase in yield was 0.38 t / ha.

The article studies the reaction of new Bellarosa potato variety on the introduction of calculated doses of mineral fertilizers and the density of planting in the forest-steppe soil of the Middle Volga region. The research shows that increased nutrition appropriately raises the yield of Bellarosa potato variety. The introduction of calculated fertilizer doses aimed at obtaining 30 tons of potato per hectare has increased the yield by 8.17–10.96 t/hectare depending on the planting density. Over 4 years of research the highest yield of 31.18 t/hectare was obtained when the planting density was 66.6 thousand tubers per hectare. It’s worth noting that higher planting density increased the effectiveness of the fertilizer introduced in calculated doses for this level of yield. The increase in potato harvest, in this case, was 4.22 and 5.81 t/hectare. The following increase in planting density with further enhancement of nutrition didn’t show such high effectiveness. For example, in the case of fertilizer dose calculated for the yield of 35 t/hectare the increase of density to 60.6 and 66.6 thousand tubers per hectare (in comparison with 55.5 thousand) gave the rise of 1.62 and 2.62 t/hectare in yield. Over 4 years of research the introduction of the fertilizer dose calculated for the yield of 40 t/hectare gave an additional 1.60 and 2.90 tons of potato per hectare.

We can expect to receive from 0.81 to 0.97 tons of sunflower oil seeds per hectare in the soil-climatic conditions of the forest-steppe zone of the Middle Volga region without the introduction of mineral fertilizers. As the doses of mineral fertilizers are increased, the productivity of 1 hectare of arable land is increased 2.8 times and the gross collections of oilseeds are 2.14 tons per hectare at the non highest background of mineral nutrition, against 0.86 tons per hectare in the control variant of the experiment (without fertilizers). The optimization of seeding rates of the studied culture is of great importance in the formation of highly productive agrocenoses. In the variants of supplementary supply of plants with nutrients, especially when N98P38K124 is introduced, the seeding rate of 70 thousand pieces per hectare of virgin seeds raises the yield of sunflower by 0.51 tons per hectare (a very solid increase in yield), compared with the sowing rate of 60 thousand pieces per hectare.

The simplest ecologically safe, energetically and economically advantageous direction for solving the problem of feed production is the expansion of the acreage of leguminous perennial grasses, since they are distinguished by high nutritional and digestibility. At the same time, it is impossible to solve the problem of balancing the ration of feeding animals only at the expense of alfalfa seedlings, clover meadow or goatskin, since in them the content of the sum of sugars does not exceed 4-6 percent. Meanwhile, in the dry matter of ryegrass of multi-hulled, the content of the sum of sugars reaches 20 percent or more. In this connection, this article deals with the cultivation of alfalfa-ryegrass stands on the calculated background of mineral nutrition in order to increase the production of energy-saturated feeds balanced by the sugar-protein ratio.

Undercrop cultivation of alfalfa is economically justified, since in the year of sowing, cover crops give a full harvest, and also one mowing of alfalfa for hay is carried out, moreover the special preparation of the soil for grasses is not re-quired. In the conditions of the Middle Volga region, the experiment was laid on leached chernozem in 2017 - 2019, where they studied the sowing of variegated alfalfa under the crops of spring wheat, barley, oats, harvested for grain and an-nual grasses - for green fodder, and studied the options for coverless sowing, where the weeds were mowed twice and the herbicide Pivot was applied at the beginning of alfalfa branching. The total biological yield is determined by the leaf area and its photosynthetic activity. Therefore, the purpose of the research is to determine the indicators of alfalfa photosynthetic activity for an objective as-sessment of the influence of cover crops on their forage productivity. It has been established that a more intensive increase in the assimilation surface of alfalfa in the first year of life to 31.6 and 30.6 thousand m2 /ha occurs on coverless sowing with the application of the Pivot herbicide and two-fold mowing of weeds. The dry matter yield was 2.1 and 2.0 t/ha, respectively. A decrease in the illumination of alfalfa plants sown under crops, where the leaf area did not exceed 13.0...15.3 thousand ? m2 / ha, slowed down the photosynthesis processes. Moreover, a more intensive growth of its photosynthetic organs was noted under the crop of barley, the cereal-legume mixture reduced the leaf area by 0.5 thousand m2 /ha, the pho-tosynthetic potential was 898...1051 thousand m2 day/ha.
