|
|
The article offers research based on field long-term stationary experiments of the agrotechnological experimental station of the Federal State Budgetary Educational Institution for the Study of the influence of pre-planting processing on potato productivity. Stimulation of the development and growth of plants is carried out during the pre-planting treatment of potato tubers. According to the research results, it was found that the pre-planting treatment of potato tubers with Florhumate and Biohumate increased the leaf surface area by 21.5...26.5% and the duration of their growing season. Treatment of humic preparations reduced the development, prevalence of Phytophthora potatoes and increased biological effectiveness...16.5 24.3% of potato tubers humic preparations increased the height of plants in average for two years, 6.5-12.1 percent. Potato yield increased from 2.3 to 2.8 t/ha and marketability of tubers 2.7...7.9%, the number of tubers 1.9...5 Grand on one Bush, the percentage of starch increased by 0,4...0,6%.
