ABSTRACT: We give the results of scientific researches for the years 2009-2013, on studying the use of growth regulators to increase stress resistance to drought at potato varieties of different ripening periods. We show the effectiveness of using growth regulators Kampozan 160 g/ha and Humate sodium 200 g/ha for spraying vegetating plants in the beginning phase of budding and after flowering, with a treatment interval of 12-14 days, and with a consumption of the working fluid of 400 hectares, and their mixtures in combination with mineral fertilizers such as chelates “Akvarin-12” (0,3% solution) with a consumption of the working fluid of 100 l/ha. The productivity of potato in drought was determined in 40% by the used drug, in 24% by genotype (Early and Middle-early variety) and in 23% by the influence of the conditions of the year.

KEYWORDS: Potato varieties; Growth regulators; Leaf area; Productivity; Quality; Drought-resistance; Ecological plasticity.
