The results of research on the study of four seeding rates (variants) and two precursors (pure steam and winter soft wheat) in the cultivation of spring durum wheat bezenchukskaya Niva are presented. Against the background of seed treatment with the preparation Baritone (1.4 l / t) on ordinary chernozem for 2016-2018, it was found that the cultivation of wheat by steam, compared with its non-steam predecessor, significantly increased the yield ratio between environmental factors (by 0.99-1.25 t/ha). The highest indicators were found at the rates of 2.0-5.0 million / ha – 3.29-3.33 t / ha, which is 0.99-1.06 t/ha higher than the values obtained for the predecessor of winter wheat. Additional production costs (27.7-29.9 %) for the cultivation of wheat by pure steam, compared with its non-steam predecessor, paid off with an increase in the yield and increased net income by 1.7 – 2.1 times, with the highest indicators for the variant with seeding rates of 1.0 and 2.0 million/ha-15475.0-15685.6 rubles/ha. The maximum level of profitability is set at the rate of 1.0 million / ha-178.7 %, which is 29.2-76.7% higher than other options for pure steam and 67.6-114.3 % of options with seeding rates for non-steam predecessor.
