Abstract
The research was carried out in order to evaluate the effectiveness of the use of biological preparations and micronutrients both separately and when used together to form the quality of winter wheat grain in the conditions of an unstable humidification zone of the Stavropol Territory. The work was carried out in 2020–2022 in the fields of the experimental station of the Stavropol State Agrarian University on leached chernozem. The experience is two-factor, the repetition is three-fold. The experience scheme includes 10 options. An economic option was adopted as a control. In the experiment, biological preparations and micronutrients were studied both independently and when used together (factor A). The studied biological preparations and micronutrients were used during seed pickling and on vegetating plants during spring tillering and flag leaf formation (factor B). The largest area of the leaf surface was obtained by the combined use of micronutrients and biologics in the phase of formation of the flag leaf. The difference with the control was 13.0 thousand m2/ha (7.5 %), with respect to the independent use of micronutrients, the difference was 13.0 thousand m2/ha (3.6 %). With the independent use of biopreparations, there are differences in the phase of formation of the flag sheet. The applied preparations, when used together, provide an increase in yield by 0.53 t/ha. The greatest increase in yield of 0.75 t/ha is provided by the application of the Standard program + VL-77 + Oracle Seeds etching + Maximum programs + VL-77 + Oracle Multicomplex in the tillering phase in spring + Pseudobacterin-3 + Biodux + VL- 77 + Oracle Sulfur Active on the flag sheet.
