Abstract
The authors presented data on the effect of the biological product Phytop 8.67 based on bacteria of the genus Bacillus on the biochemical composition and yield of tubers during the pre-planting treatment of potatoes in 2018. The authors conducted experiments on the early-ripening potato variety Rosara in the soil-climatic zone of the forest-steppe in the conditions of leached chernozem of the experimental fields of the Educational and Production Farm (EPF) “Michurintsev Garden.” At pre-planting treatment of potato tubers, Phytopom 8.67 mass fraction of dry matter was 17.62%, which was significantly higher than the control variant. In the experimental version, there was a significant increase in protein content in potato tubers from 14.4% to 15.9% relative to the control variant, while the range of ash elements decreased. The authors note that using the bio preparation Phytop 8.67 reduced the infection of tubers with sclerotia and other forms of Rhizoctonia Solani Kuhn by three times compared with the control. The biological effectiveness of the application was 66.4%.
