摘要:To obtain high yields of potatoes, plant growth and development regulators of various origins are used. Recently, the use of chemicals made from natural raw materials has become more widespread. One of them is the chemicals Relict based on humic and fulvic acids, which have growth-stimulating adaptogenic and protective properties from peat. It is used both for treatment of tubers before planting, and for vegetative plants treatment. Such treatment allowed to reduce the sparseness in potato plantings, and also contributed to an increase in the yield of large and medium fractions of tubers. The marketability of tubers in the control is 81.7%, and in the areas treated with Relict is higher - at a concentration of 0.01 % - 91.6 %, and by 0.05 % - 93.7 %.
