Abstract: The paper is focused on the influence of synthetic growth regulators on the biological productivity of potato plants and on some biometric indicators in nursery conditions on sod-podzolic soils. The field method was used for this research; after measuring the metric and weight properties, the data obtained were further subjected to statistical analysis of variance. A positive effect of growth regulators (Amulet, El-1) on the productivity and quality of improved potato varieties of the early variety Udacha in the system of original seed breeding has been discovered. The use of growth regulators on potato in nursery conditions contributed to increasing the vegetative mass of plants, the yield, the reproduction rate, and the qualitative indicators, to reducing the content of nitrates in the tubers, and to improving plants’ resistance to late blight and viral diseases.
