Abstract
At present winter wheat is the leading grain crop in the Volga region and Russia. However, it’s necessary to improve its cultivation technologies to increase its efficiency. The purpose of the work is to identify the optimum sowing methods and rates of winter soft wheat with the application of disinfectant ‘Stsenik Kombi’ in the climatic conditions of the Middle Zavolzhie. In 2015–2018 there was estimated the influence of two sowing methods (row and wide-row) and five sowing rates of the winter wheat variety ‘Svetoch’ when applying disinfectant ‘Stsenik Kombi’ in comparison with the control variety. It has been established that the highest net income (12251.5–12498.3 rubles/ha) and level of profitability (107.7–121.5%) were obtained on options with the sowing rate of 2.0–4.0 million/ha. The highest breeding rate was found in the usual ordinary sowing rate of 1 million/ha to 100 (in 2016), which is in 2–4 times higher than when sown with the rate of 2.0–5.0 million/ha. The obtained regularity indicates the prospects of this sowing rate when cultivating seeds of high reproductions for seed production purposes, both in ordinary row sowing (the width of the spacing is 15 cm), and in wide-row sowing (30 cm). When sowing 2.0 million/ha or more, there was established a prevalence of ordinary row sowing over wide-row sowing on 0.4 t/ha (or 16.9%). The application of disinfectant ‘Stsenik Kombi’ is recommended in winter wheat cultivation.

Summary
Оценено влияние двух способов посева (обычный рядовой и широкорядный) и пяти норм высева озимой пшеницы Светоч при применении протравителя Сценик Комби в сравнении с контролем. Цель работы – выявление на фоне применения протравителя Сценик Комби оптимальной нормы высева и способа посева озимой мягкой пшеницы в сложившихся климатических условиях Среднего Заволжья. 2018 гг.) озимой пшеницы Светоч при применении 4-компонентного инсектофунгицидного протравителя Сценик Комби, КС (клотианидин 250 г/л + протиоканазол [37,5] г/л + тебуконазол 5 г/л + флуоксастробин [37,5] г/л) с ростостимулирующим эффектом проведено в многолетнем стационаре в зернопаровом севообороте на черноземе обыкновенном
