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.

Abstract. The purpose of the research is to evaluate the adaptability parameters of zoned and promising varieties of spring soft wheat and to identify samples that combine high grain yield and adaptive properties for forest-steppe conditions of the Middle Volga region. The work was carried out in 2017–2020 in the central zone of the Samara region. Methods. The object of research was 12 varieties of competitive testing related to different stages of breeding. Observations and records were carried out according to the Methodology of the state variety testing of agricultural crops, assessment of the adaptability of varieties according to the methods of A. A. Goncharenko and L. A. Zhivotkov. Weather conditions in 2017–2020 were diverse and varied from the average annual values. Results. The average crop yield varied from 2.10 t/ha (2019) to 3.72 t/ha (2017), the coefficient of variation Cv = 23.8 %. Varieties with a high average grain yield (3.15–3.26 t/ha) and a smaller variation (19.9–22.5 %) were identified – Eritrospermum 6310/10-63, Lutestsens 6102/1-32, Eritrospermum 6517/24-1. The varieties Eritrospermum 6310/10-63 (–1.39), Eritrospermum 6381 (–1.50), and Kinel’skaya 59 (–1.50) had the greatest resistance to stress. Varieties Lutestsens 6045, Kinel’skaya yubileynaya, Lutestsens 6102/1-32 – differed in specific adaptation and formed the highest average grain yield (3.16–3.20 t/ha) under contrasting conditions. The average coefficient of adaptability of varieties ranged from 0.85 to 1.08. The majority of varieties (58.3 %) had a high coefficient of adaptability (greater than 1), the highest values (1.08) were the promising varieties Lutescens 6102/1-32 and Erythrospermum 6310/10-63. Scientific novelty. A new adaptive material of spring soft wheat has been isolated for use in breeding programs of the forest-steppe zone of the Middle Volga region.

For the forest-steppe of the Middle Volga region, efficiency of preparations for presowing treatment of seeds as regulators of the phytosanitary state of agrocenoses and spring wheat productivity for different regionalized varieties were assessed. To obtain stable phytosanitary agrocenoses, in the Middle Volga region, Kinel Yubileynaya variety should be cultivated with pre-sowing seed treatment using Epin Extra.

The article presents results of studies of influence of controlled and environmental factors on production process of different varieties of spring wheat carried out in different soil and climatic conditions of Middle Volga region. The forest-steppe area of the Volga region is one of regions of Russia favorable for spring wheat growing by its natural and climatic conditions. Unbalance of nutrition elements in soil, acid soil and predominantly heavy-textured soil hamper the yield growth. Out of all factors vital for plants (light, heat, moisture and nutrition elements) under consideration, providing plants with nutrition elements and moisture are those limiting high crop yields. he objective of our studies is increasing the crop yield with the simultaneous decrease of the produced goods cost makes it necessary to calculate in advance the possible yield level depending on the influence of different factors: environmental, crop variety and etc. The aim of our studies was to develop methods of growing high yield and high quality crops of different varieties of wheat adjusted for conditions of the forest-steppe black soil in the Volga region. Methods of research using field and laboratory tests, the method of state variety tests of agricultural cultures, phenoldisulfonic acid method, finite difference method, disperse analysis method. A set of observations, records and analysis was carried out during the experiments with implementation Russian methodological guidelines and National State Standards. Statistical processing of the yield data, economic and energy estimates was carried out by the methods recommended by Russia Scientific Research Institute of Agricultural Economy and Union Academy of Agricultural Sciences. Having carried out the analysis of natural resources and genetic potential of the wheat varieties, systems of plant nutrition optimization and influence of their predecessors, we have obtained new data about possibility of increasing the spring durum wheat arable area. We have shown the role of different forms of using nitrogenous fertilizers (on the background of phosphorus – potassium ones) in the increase of productivity and improvement of the spring wheat grain quality. An established optimal norm for Gramma variety spring spelt corn seeding has been established for the conditions of the grey forest soil in the Fore-Kama region of the Republic of Tatarstan and the influence of their nutrition on yield has been found.

In wheat selection, the earring period is a fairly reliable criterion for determining the ripeness group of the variety. The aim of the research was to determine the maturity groups of winter soft wheat varieties of various ecological and geographical origin in the middle Volga forest-steppe. 18 varieties of winter soft wheat included in the State register of selection achievements for the middle Volga region of Russia were used for research in machine seeding.102 varieties originating from 11 countries were used in manual seeding. It is established that the intra-and intervariental change of the date of winter soft wheat earning is weak and moderate. The share of genotype (variety) influence in the variability of the duration of the growing season of winter soft wheat is 56.1 %, the year conditions-4.4 %, and the “genotype-year” interaction-36.5 %. Among the assortment of winter soft wheat of domestic selection, 54% of varieties showed themselves to be medium – ripe, 24% – medium-early, 10% - medium-late. The late-maturing, early-maturing, and ultra-early-maturing groups only included single varieties in certain years. Among the studied assortment of the world wheat collection late maturity had variety of Germany, the earliness and medium early– wheat of China, Japan, Bulgaria and the North Caucasus region of Russia, medium maturing varieties of the Siberian region of the country. Wheat of different groups of ripeness were represented by varieties of Ukraine. The ultra-early and late-maturing varieties of foreign selection selected in the study are valuable as a source material for the selection of soft wheat for the duration of the growing season in the middle Volga forest-steppe.
