The results of studies of five sunflower cultivation variants within the production system ExpressSun™ on ordinary chernozem for 2013-2019 in the southeastern European part of Russia (the hydrothermal index for the growing season – hereinafter HTI – is 0.70) are presented. It was found that when switching to the systemic principle of formation, cultivation technologies based on differentiated soil tillage in crop rotation provided an increase in soil productive moisture reserve to the emergence of sunflower seedlings, in comparison with the traditional technology by 5.8-12.2 mm (3.8-8.0%), P2O5 content - by 2.0-27.2 mg/kg (1.0-8.9%). The highest sunflower oilseed productivity 2.52-2.56 t/ha was revealed when using complex fertilizers, which was 0.25-0.43 t/ha (11.0-20.2%) more than other options. Despite the very high content of K2O in the soil, the yield was in direct proportion to this macroelement (r = 0.32-0.85*). The highest conditional net income 27070.2 rubles/ha was established against an intensive background of resourse-saving technology, which was 970.0-3780.5 rubles/ha (3.7-16.2%) more than other studied options. Based on the data obtained, a low-cost technology of sunflower cultivation has been developed, which includes the following technological operations: applying complex mineral fertilizers (NPK)15, deep soil tillage by 25-27 cm, spring harrowing, pre-sowing cultivation, packing, sowing, harrowing in one track, herbicide treatment, and top-dressing. The expected annual economic effect from the development of new technologies for sunflower cultivation is more than 1100 rubles/ha.

“…With the growth of agricultural technology, the introduction of farming intensification, the values of the indicator decreased and stabilized at a certain value (Equation 5), where: Ya -actual yield of the main product at standard humidity, dt/ha; E -total water-use of crops during the vegetation period, mm. The maximum possible potential yield (Ypp m) in terms of moisture supply was calculated using the same formula as the actual possible potential yield (Ypp a), but according to the longterm annual average moisture reserves (W) in the soil 453.8 mm (Goryanin et al, 2019) and the optimal moisture requirement according to M. K. Kayumov (1989). The optimal moisture requirement for winter crops (Rw) was 326 mm (Bykov, 1968).…”

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 article presents the results of studies to identify the influence of abiotic factors on the grain quality of varieties and lines of winter triticale of the Samara Research Institute of Agricultural Sciences for 2017-2020, in comparison with varieties of winter rye and wheat. The studied crops were cultivated in the fields of the institute, located in the black earth steppe of the Middle Volga region. Technological properties were determined in the laboratory of the technical and analytical service of the Samara NIISH and at the Faculty of Technology of the Samara State Agrarian University according to standard generally accepted methods. The data obtained indicate a higher productivity of modern triticale varieties, compared to rye and wheat. In terms of grain quality, these varieties and lines are superior to winter rye varieties and are not inferior to wheat. On average, over 4 years, the content of HAC in triticale varieties was (1.09-1.51 mp · S), with a variation by year, depending on climatic conditions from 0.90-1.53 mp · S in 2017 to 1.01-1.59 mp · S in 2018. It was revealed that the varieties Krokha and Arcturus were distinguished by the fat content of 1.81-1.85 %, the variety Spika and liniya 9385-4/14 1,72-1,75% – by ash content. In terms of the content of almost all amino acids, the grain of the 830-4/13 line was superior to the rest of the studied samples. The amount of protein in the grain varied from 11.7 to 15.6% over the years, and fat from 0.61 to 2.55%. A high yield relationship was observed with the content of pentosans r=-0.82±0.08, arginine r=-0.72±0.12, with the mass of 1000 grains r=0.67±0.14, histizine r=0.61±0.16, leucine r=-0.69±0.13, sodium content r=0.86±0.06, and depended on the amount of precipitation in April r=0.81±0.08. The necessity of analyzing the amino acid composition of triticale grain to determine its biological value is justified
