Abstract. The experiments were conducted at Samara Research Institute of Agriculture, a branch of the SamSC RAS in 2018–2020. The purpose of the research. Evaluation of promising lines of peas from the competitive variety trial nursery for the nutritional quality of seeds to create new varieties for the Middle Volga region. Methodology and methods of research. The material for the study was 6 promising lines of peas. The nutritional quality of the lines were evaluated according to the following characteristics: the protein content and composition in the seeds, the boiling time of the seeds, the seed cooking coefficient, and the taste of the boiled seeds. The peas grew and developed in dry (2018–2019) and moderate (2020) weather conditions. Results. The protein content in the seeds of the lines was determined by external environmental factors, especially the weather conditions during the bean filling phase. The seeds accumulated more protein when the weather was dry during the bean filling. The protein content of seeds had a positive correlation (r = 0.944) with the average daily air temperature, and a negative correlation (r = 0.986) with precipitation during the bean filling phase. On average, the lines had the same protein content as the Samarius standard but corresponded to the standard value of high-quality varieties (not less than 24.0 %). The following lines had the same seed protein content as the standard (25.6 %): B3737/2-2 (25.2 %), Kt6575 (25.8 %), Kt6358 (24.9 %). These lines contained a large amount of water-soluble protein fraction in comparison with the standard: Kt6575 (16.9 %), Kt6358 (16.6 %), and B3737/2-2 (16.9 %). B3737/2-2 and Kt6575 showed high cooking quality (seed boiling time 110–122 minutes, seed cooking coefficient 2.5–2.6). All lines had a good taste of boiled seeds equal to 4–5 points. Scientific novelty. B3737/2-2, Kt6575, Kt6358 have been suggested to be used as sources of new varieties for their high cooking quality.

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 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 epidemic transition is the most important part of the demographic transition, which in turn determines the current trends in fertility and mortality in modern Russia. The paper attempts to trace the main regional features of the process by the example of the Middle Volga Region. Using the statistics reported in the census, statistical handbooks, central and local archives, the author traces the changes in morbidity and mortality of the urban population of the Middle Volga Region, making the conclusion that the epidemiological transition in the region was essentially completed in the period of the Khrushchev thaw. There was also a rapid increase in mortality from malignant neoplasms and circulatory diseases, which is characteristic of the final stage of the epidemic transition. The author of the paper revealed some lag of the region in terms of exogenous morbidity. It was associated with the rapid growth of industry in the region, and as a consequence, not always appropriate conditions of hygiene and life of the urban population. However, mortality trends in the Middle Volga Region corresponded to those in the RSSR as a whole, which was primarily due to the achievements of medicine of the time: the emergence of antibiotics, mass vaccination of the population, improving the quality of medical services.
