Abstract. Efficient and rapid decomposition of plant residues, and elimination of the negative impact of pathogenic microflora on the soil environment and the plant organism occurs due to fungi of the genus Trichoderma, which have phytoprotective and growth-promoting properties, have a high degree of decomposition of high-polymer components of plant residues. One of these drugs is Sternifag. The article presents the results of studies that determine the effectiveness of the use of the microbiological preparation Sternifag in the technology of cultivating winter wheat. The research was carried out at the Adyghe research institute of agriculture in the period 2017–2020 years on leached chernozem. As a result of the research, it was noted that the use of the Sternifag preparation increased the height of winter wheat, which was 37,4 cm in the booting phase (+39,6 % of the control) and 81,9 cm in the full ripeness phase (+8,9 % to control), the growth of biomass by aboveground organs and their accumulation of dry matter also increased. The inclusion of the Sternifag preparation in the winter wheat cultivation technology significantly increased the yield by 11,2 (low agrobackground) and 9,3 (high agrobackground) % in comparison with the options without its use. The maximum yield – 4,01 t/ha, was obtained on option 4 with the Sternifag preparation, on a high agricultural background. It was determined that the use of this drug in the cultivation of winter wheat improved the protein content in the grain, its nature, and vitreousness. At the same time, it slightly affected gluten and its quality, which determined the grain class, which corresponded to 5 on a low agricultural background, and 4 on other options.
Keywords: Triticum aestivum L. (winter soft wheat), fungi of the genus Trichoderma, Sternifag preparation, organic matter, crop structure, yield, grain quality.
