The study of winter crop cultivars was carried out in the breeding fields of the Samara Agricultural Research Institute, located in the steppe zone of the Middle Volga region, in the nursery of competitive testing in 2002-2019. For calculations, 5 varieties of winter rye, 6 varieties of winter triticale, and 2 varieties of winter wheat were taken. For scientific justification, the authors calculated the potential productivity (Yp), the actual possible potential yield (Ypp a), the maximum possible potential yield (Ypp m), the bioclimatic potential (BCP), and correlation analysis. The study aims to calculate the possible yield of winter crops to substantiate the data obtained scientifically. In the dry conditions of Bezenchuk, the maximum yield of triticale was obtained in 2017 – 7.48 t/ha, rye – 5.88 t/ha, and in 2016 for wheat – 4.65 t/ha. Potential productivity, taking into account ΣT>10 °C for the vegetation period of the crop, for triticale in 2017, 3.02 t/ha, for winter rye in 2005, 6.83 t/ha, for winter wheat in 2005-2.79 t/ha. The variation of the indicator (BCP) over the years reached significantly higher values from 0.62 to 1.16 points for winter rye, from 0.30 to 0.60 for winter triticale and winter wheat. The trend of the interrelations between yield is observed with the length of the vegetation period, with a set of climatic conditions for the springsummer period. The triticale vegetation duration depends on the precipitation in May and on the set of conditions in June. The winter rye vegetation duration depends on the temperatures during the sowing-germination period and on the sum of active temperatures during vegetation.

The study of 5 varieties of winter rye, 6 varieties of winter triticale and 2 varieties of winter wheat of winter crops was carried out in the breeding fields of the Samara niish, located in the steppe zone of the Middle Volga region, in the nursery of competitive testing in 2002-2019. For scientific justification, we calculated the potential productivity (Ut), the really possible potential yield (Double p), the really possible maximum yield (Double m), the bioclimatic potential (BCP), and correlation analysis. The purpose of the work: to determine the possible yield of winter crops and propose measures to achieve the data obtained in the arid conditions of the Volga region. In the conducted studies, the maximum yield of triticale was obtained in 2017 – 7.48 t / ha, rye-5.88 t / ha, wheat in 2016-4.65 t / ha. The potential yield, taking into account ?T10°C for the growing season of the crop, for triticale was obtained in 2017 -3.02 t / ha, for winter rye in 2005-6.83 t / ha, for winter wheat in 2005-2.79 t / ha. The variation of the indicator (BCP) over the years reached significantly higher values from 0.62 to 1.16 points for winter rye, from 0.30 to 0.60 for winter triticale and wheat. With rational plant protection from weeds, pests and diseases and optimal plant nutrition, the studied varieties are able to grow intensively in the arid conditions of the Volga region, form a good strong root system, a well-developed conducting stem system, a large ear that can intensively use the flow of heat energy, and consistently provide a yield of 3.0-4.0 t / ha.

The purpose of research is to increase the productivity and quality of winter wheat variety trials competitive grain varieties, depending on weather conditions. Studied varieties: Povolzhskaya 86, Kinel’skaya 8, Povolzhskaya niva, Konstantinovskaya. Varieties cultivated by traditional technology, the fresh pair. The data for the 2012-2015 biennium. Grain quality was assessed a number of indicators that characterize its physico-chemical and technological properties: nature grain, vitreous, the strength of flour, protein content, adhesive wine. The maximum value in terms of nature is characterized by grain corn all classes in 2013 and 2014 (782-816 g/l). The high rate of vitreous grains observed in 2012, 2014, 2015 (72-92%). Good data on the same data obtained for the protein content, wet gluten flour strength. It was found that the environmental conditions during the formation and ripening of grain in years of research have a significant impact on productivity and ka-honors winter wheat. The study group of varieties set up in the laboratory breeding and seed, has a rapid rate of accumulation of dry matter. They are adapted to the formation of us, full grain in the conditions of unstable arid climate of the Middle Volga region.

Tillage Treatment

The aim of the study is to increase the yield of winter wheat with the use of innovative organic fertilizers during overall tillage in conditions of the forest-steppe zone of the Middle Volga region. The research was conducted in the period involving 2017-2020. The Svetoch variety winter wheat plants, were subjected to the research. In the field experiment, organic fertilizers were applied at different tillage treatment stages. The fertilizers use during early spring sowing or winter crops aftergrowing contributed to an increase of moisture content in the meter-depth soil layer by 0.8-1.3%. Winter wheat harvesting was not affected by the soil moisture significantly depending either on fertilizers used or main tillage treatment. The organic fertilizers use led to a slight decrease in soil compaction during the sowing of early spring crops or winter wheat spring aftergrowing compared to the option without fertilizers. The in-troduction of fresh manure led to a certain increase in the contamination of crops, after the introduction of other or-ganic fertilizers studied, the number of residues and their weight was less, and no significant differences were ob-served between the variants. Factor A showed (organic fertilizers applied) during periods of 2017-2020 the yield of winter wheat was – 2.95 t/ha; fertilizers were not applied, when 30 t/ha of manure applied – 3.32 t/ha; dry organic fertilizer use – 3.35 t/ha; and liquid one – 3.36 t/ha; biohumus – 3.32 t/ha. An increase of winter wheat yield from the action of organic fertilizers was 0.37-0.41 t/ha (or 12.5-13.9%). According to factor B (main tillage), the crop yield amounted to: when plowing by 20-22 cm – 3.33 t/ha; surface tillage by 10-12 cm – 3.25 t/ha; without autumn cultural practice – 3.19 t/ha. The use of resource-saving tillage reduced the winter wheat yield by 0.08-0.14 t/ha (or by 2.5-4.4 %), that is, without a significant difference between the options.

Winter hardiness of plants depends on many factors: plant species, variety, duration of quenching phase and meteorological conditions. The reaction to stressful influences during the autumn-winter period is the changes in the cellular metabolism, in which the accumulation of various substances that protect plants from death occurs. Proline is a multifunctional amino acid, that accumulates in high concentrations in response to various abiotic stresses. The purpose of this study is to identify species and varietal differences in the accumulation of proline in winter crops in the Republic of Tatarstan. The material for research was the leaves of winter wheat plants (Triticum aestivum L.), winter rye (Secale cereale L.) and winter triticale (Triticosecale Witt.). The experiments were carried out under conditions of natural stress factors of three consecutive growing seasons of 2014-2017. To determine the state of wintering plants in dynamics, the content of free proline was determined by the Bates method. It is shown that the average values of proline content in winter rye and triticale increased from October to December, but decreased in February. Winter wheat had a further increase in the indicator. The amplitude of the oscillations in December in winter rye was 5.18-13.52 μmol/g, in winter triticale - 9.47-23.15 μmol/g, in winter wheat - 25.81-32.98 μmol/g. The greatest variability of proline values in the studied cultures was noted in February. For each of the winter crops, its reaction rate according to this criterion was revealed. However, there is an intraspecific specific character of the dynamics of the synthesis and breakdown of free proline. Among the studied varieties and hybrids of winter rye, 3 groups differed among themselves. The concentration of proline in the leaves of winter triticale approximated to the values of winter rye, and according to the dynamics of accumulation - to winter wheat.
