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 %.

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 increase in productivity, quality of sunflower seeds is largely dependent on the optimal doses of fertilizers and plant density in relation to a particular variety and agroclimatic conditions of the region. The aim of our research was to study the effect of the seeding rate and the background of mineral nutrition on the productivity and quality of seeds of Orenbar sunflower hybrid. The application of mineral fertilizers in a dose of N90P60K90 on average for four years ensured the formation of a crop with a planting density of 47 thousand pcs per hectare – 1.536 tons per hectare. As the seeding rate increased to 74 thousand pcs per hectare - the productivity increased by 0.376 tons per hectare and amounted to - 2.839 tons per hectare against the background of mineral fertilizers in the dose of N90P60K90. This variant had the highest oil yield – 1.463.9 kg per hectare.

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 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 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.
