In recent years, fertilizers and biological products are widely used for cultivating perennial grasses to form highly productive agrocenoses and reduce the cost of feed. The issues of the use of biologically active substances for pre-sowing seeds of perennial herbs in combination with leaf fertilizing are of great practical importance. In the soil and climatic conditions of the Middle Volga region, the pre-sowing seed treatment with Azotovite 2 kg/t in combination with leaf treatment with Flavobacterine 4 l/ha depending provided an additional yield of 2.5–4.8 t/ha of green mass with a content of 440–960 feed units. The effect of the above biological products is equivalent to the application of 70–88 kg/ha of mineral fertilizers and cost savings in the amount of 1.5–1.9 thousand rubles/ha.

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.

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.

Direct Sowing

It is given the impact of direct sowing technologies with different levels of intensity of arable land use, in comparison with the traditional tillage, on the elements of fertility of ordinary chernozem and productivity of spring durum wheat in the middle Volga region. The complex application of direct sowing technology using straw as fertilizer stabilizes with traditional technology the supply of soil with nitrogen, increases the content of mobile forms of phosphorus in it by 1.5-21.2%, potassium exchange – by 10.4-18.3%.   Improving the nitrogen regime of the soil in direct sowing, in which the starting doses of nitrogen fertilizers were combined with integrated plant protection, provided the highest grain yield – 1.76-1.79 t/ha, which is 0.41-0.44 t/ha (30.4-32.6 %) higher than the control. The increase in yield from the use of biological products was 0.15 t / ha (11.9 %), nitrogen fertilizers N30 – 0.17 t/ha (13.4 %), the combined use of fertilizers and insecticides 0.50-0.53 t/ha (39.7-42.0 %). The highest cost recovery was after direct sowing with a maximum level of intensification-1.98-2.02 rubles/ha, which is 0.14-0.32 rubles/ha higher than the other options. The smallest economic indicators obtained in the control to 1.54 rubles/ha. According to the results of research with direct seeding of spring durum wheat in the region is proposed on the background of integrated plant protection application of calculated doses of mineral fertilizers on yield of 2.0 t/ha (pre-sowing, local-band application).

The aim of the research was to increased fodder and seed productivity of variable alfalfa (Medicago varia Martin) in the middle Volga region. The results of the researches made during the period 2012-2014 for incorporated 13 vari-ety samples of alfalfa changeable in the nursery of competitive trials are provided. The most promising population demonstrated economically valuable traits in previous years, from various nurseries of the study were used. Popu-lation was created by the polikross. Weather conditions analysis of the region allows us to conclude that over the 2012-2014 they met the requirements needed for the studied culture, providing a sufficiently high potential of productivity, but the limiting factor for the formation of the vegetative mass of alfalfa is the level of moisture. The data on the possibility of obtaining seeds in the year of sowing in the climatic conditions of the Middle Volga region un-der the condition of early sowing (until 10-12 may) are confirmed. Seed yields in 2012 ranged from 24.7 to 47.8 g/m2. It was found that in different years of moisture supply, taking into regard the conditions of the region, all the studied samples form 2 full-fledged mowing per season. All studied samples can be characterized as highly pro-ductive by vegetative mass and seeds. The dry matter accumulation in the estimated samples in the first mowing of 2013 was 0.65-0.68 kg/m2, in the second – 0.38-0.86 kg/m2. In arid 2013, the highest yield of seeds was obtained 337.5-494.7 g/m2. In 2014, the yield of dry matter both mowing was approximately equivalent 0,56-0,79 kg/m2 and 0.54-0.97 kg/m2 respectively, the average for the samples is 0.66 kg/m2 in the first mowing and 0.67 kg/m2 in the second. The yield of seed populations in 2014 ranged from 22.9 to 55.8 g/m2. All studied samples can be charac-terized as highly productive for the accumulation of dry matter and seed yield.

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 density of wood inside the stick varies greatly according to the diameter and height of the tree. The development of a non-destructive method of predicting an average density of wood in all specific breed stem-base density in parts of the tree is of great practical importance. For this purpose, the research was conducted to identify the patterns of wood density dynamics against the height and the diameter of birch trees growing in the conditions of the Middle Volga Region in Russia. Fourteen model birch trees (Betula pendula) were selected as research material on two plots in the plantations of the Scientific-Experimental Forest District of the Volga State University of Technology (VSUT) in the Republic of Mari El of Russia. From each felled model tree 50.0 mm cross-section discs were carved at a distance of 1.3 m from the root collar and at relative heights of 0.25H, 0.5H, and 0.75H. Prototypes in the form of 20x20x30 mm rectangular prisms (long side along the wood grain) were made from their north and south sides at a distance of 0.25R, 0.5R and 0.75R from the stem core along the NS diagonal. Density studies were conducted by measuring the density of the wood sample immersed in liquid against the buoyant force. It has been revealed that there are both differences and patterns of change in density in the longitudinal and cross-section directions of the trunk of a birch tree growing in the conditions of the Middle Volga Region in Russia. Based on the results obtained, a mathematical model of these laws has been formulated. Сlose relationship between the average density of the stick and its diameter at breast height (DBH) cross-section average density, i.e. ρtree=178.52+0.641ρdbh (r=0.922) has been revealed. By applying a well-known method of determining the density of cross-section radial core extracted from the wood by an age borer at this height, wood density of the birch trees growing in the Middle Volga Region can be calculated according to this equation.

Целью исследований являлась оценка урожайных свойств и основных параметров адаптивности сортов сафлора красильного в агроклиматических условиях лесостепи Среднего Поволжья. Исследования проводили в 2017-2019 гг. на опытном поле Пензенского института сельского хозяйства. Объектом исследований являлись шесть сортов сафлора красильного. Метеорологические условия периода вегетации характеризовались как засушливые, где гидротермический коэффициент (ГТК) колебался от 0,4 до 0,82 единиц. Индекс условий среды варьировал в пределах от - 0,61 до 0,13 единиц. Наиболее оптимальные условия для развития культуры сложились в 2019 году (Ii – 0,13), где сформировалась наиболее высокая урожайность семян по всем сортам 1,34-1,53 т/га. Высокий урожай отмечен у сортов Заволжский 1 и Александрит, продуктивность которых составила 1,37 и 1,42 т/га, соответственно. Коэффициент изменчивости урожайности составил 6,58-14,19 %. Низкая вариация урожая по годам отмечена у сортов Ершовский 4 и Астрахансий 747 (6,58-7,71 %), что говорит об их стабильности. У данных сортов был наиболее высокий показатель уровня стабильности сорта (ПУСС) и составил 0,26 и 0,22 соответственно. Сорта Заволжский 1, Астраханский 747 и Александрит сформировали крупные семена, масса 1000 семян их достигала в среднем 41,4-41,6 г. Содержание жира в семянках колебалась в пределах 23,70-27,45 %. В условиях Пензенской области лучшими по экологической адаптивности были сорта Заволжский 1 и Александрит, параметры адаптивности которых составили bi = 0,99-1,01; σdr2 = 0,09. Наиболее высокие значения индекса стабильности (0,17 и 0,20) имели сорта Александрит и Ершовский 4, что показывает их большую приспособленность к конкретным условиям. The purpose of the research was to evaluate the yield properties and the main parameters of adaptability of safflower (Carthamus tinctorius) varieties in the agricultural climatic conditions of forest-steppe of the Middle Volga Region. The research was conducted in 2017-2019 on the experimental field of the Federal Scientific Center of Bast Crops. The object of research was the six varieties of safflower (Carthamus tinctorius). Meteorological conditions of the growing season can be characterized as dry; the hydrothermal coefficient (HTC) ranged from 0.4 to 0.82 units. The index of environmental conditions varied from - 0.61 to 0.13 units. The most optimal conditions for the growth of culture were formed in 2019 (Ii – 0.13), where the highest seed yield for all varieties was formed – 1.34-1.53 t/ha. Zavolzhskij 1 and Alexandrit varieties were registered with the high yield, whose productivity was 1.37 and 1.42 t/ha, respectively. The coefficient of yield variability was 6,58-14,19 %. On an annual basis, the low variation in yield was observed in the varieties Ershovskij 4 and Astrahanskij 747 (6.58-7.71 %). This fact indicates the stability of these varieties. These varieties had the highest variety stability level and amounted to 0.26 and 0.22, respectively. Varieties Zavolzhskij 1, Astrahanskij 747 and Alexandrit formed large seeds. The weight of 1000 seeds reached 41.4-41.6 g on an average. The fat content in the achenes ranged from 23.70-27.45 %. In the conditions of the Penza region, in terms of environmental adaptability, the best varieties were Zavolzhskij 1 and Alexandrit, whose adaptability parameters were bi = 0.99-1.01; σdr2 = 0.09. The varieties Alexandrit and Ershovskij 4 had the highest values of the stability index (0.17 and 0.20). This fact shows their greater adaptability to specific conditions.
