The article examines the materials of the beginning of the Migration period from the Biklyan’ settlement, located in the Lower Kama region. The area of 100 m2 was excavated in 2018, where a rectangular structure slightly deepened into subsoil loam with a large pit in the central part was revealed. The finds are mainly represented by fragments of ceramics, as well as an iron sickle, spinning whorls, a fragment of a crucible and ceramic objects of unknown purpose. The artifacts from the Biklyan’ settlement have close analogies in the materials of the sites dated to the beginning of the Migration period in the Middle Volga region (3rd–4th centuries CE) and reflect the traditions of several different population groups. The bulk of the ceramics collection is similar to the vessels of the Middle Volga variant of the Kiev culture; there are also fragments that find analogies in the assemblages of the forest-steppe peripheral sites of the Late Sarmatian world and in the simultaneous cultures of the Kama region. Stratigraphic records and radiocarbon dating testify in favor of the relatively short-term functioning of the site in the late 3rd – early 4th centuries.

The microtoponymy of the Middle Volga region is of particular interest to the author because of the polyethnic and multilingual environment. It is a region of cohabitation of Slavic, Turkic and Finno-Ugric population groups. The facts of ethnocultural interaction are revealed in substrate microtoponyms, which often have Turkic origins.There are also Finno-Volga substratum elements.Many of them were reinterpreted in Russian language.

Maturity Groups

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.

The work presents the results of studies for 2017-2019, aimed at developing methods for increasing the productivity of sunflower hybrids cultivated according to the Clearfield system when using the microfertilizing mixture Agromineral in the forest-steppe zone of Middle Volga region. The results of the studies showed that the safety of plants at the time of harvesting is up to 91.8%; the maximum safety is achieved when processing crops by vegetation with Agromineral microfertilizing mixture at a dose of 3 l/ha. The leaf area increased until the budding phase, reaching a maximum of 99.2 thousand m2/ha, on a mid-season hybrid when processing crops with a dose of 3 l/ha, and then, due to drying of the lower leaves, it begins to decrease to the phase of the onset of flowering to 37.8 ... 57.9 thousand m2/ha. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8N477KLDM - 4.781 million m2/ha days. The use of fertilizers and micronutrient mixtures increases its value and, as a result, increases productivity by 9.09 ... 9.36 kg/ha with an absolute indicator of 27.2 ... 33.2 kg/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.
