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.

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 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 main biotic factors determining the level of productivity potential of winter soft wheat in the Samara region are the amount of rainfalls before seeding and during the vegetation period, as well as the optimal temperature regime. The aim of the research was to evaluate winter soft wheat varieties at the final stage of the selection process (competitive variety testing) in different weather conditions. The research was conducted in Povolzhye SRISB-branch of SamRC RAS in 2016-2019. Winter soft wheat varieties were selected as research objects: Volga 86, Povolzhskaya Niva (included in the State register of selection achievements), Povolzhskaya Nadezhda (undergoing variety testing since 2019), as well as Erythrospermum 3730 and Erythrospermum 3765 varieties that have been distinguished over the years of research. Varieties were seeded on autumn fallow in four-fold repetition with a registered plot area of 25 m2. Meteorological conditions for 2016-2019 were analyzed, and their impact on the productivity and quality of grain of winter wheat varieties selected by Povolzhye SRISB was determined. Raindrop of the warm period (April-July)had a significant impact on the yield. The growth season of 2019 was characterized by less favorable weather conditions (the amount of raindrops to the norm – 65.3 %). The most adapted to the stress factors of the environment were varieties of local selection. In this regard, it is necessary to introduce varieties that are resistant to stress factors of the Middle Volga region, capable of producing stable grain yields with the use of mineral fertilizers.
