Abstract: Three-year researches have been conducted to study the effect of microbiological products on the yield and quality of commercial products of peppermint. The subject of the study was phenological changes, biometric indicators and parameters of crop yields, depending on the application of such microbiological products as EM-A, Siaivo-2 and EM-plates. During the scientific work, field, statistical, laboratory research methods were used. Phenological observations, biometric measurements, accountings and biochemical analysis of plants were carried out. As a result of the research conducted, the consistent pattern of the formation of a high level of yield of the commercial products of peppermint, depending on the use of EMproducts, are substantiated. Thus, the fertilizing of peppermint plants during the growing season with a solution of the microbiological preparation EM-A stimulated the growth of leaf mass and improved the foliage of the plants. Accordingly, the yield of plants of this variant of the experiment was the largest — 3.9 t/ha. The results show that when exposed to microbiological products, regardless of their choice, the content of nitrates in the green mass of peppermint decreased compared with the control. In addition, our studies revealed a tendency to an increase in the content of essential oil in peppermint leaves under the influence of microbiological products. The positive effect of microbiological products on the growth, development and yield of this crop has been proved and it has been determined that the use of the microbiological preparation EM-A by fertilizing during the growing season can be included as an effective, environmentally safe element in modern technology of growing this culture.
