Abstract
The article presents the results of studies conducted on the southern soil in the south 2016-2018 with sunflower culture. The article presents the results of study of resource-saving approaches to plant nutrition through the use of state-of-the-art regrowth preparations, their effect on the growth processes of sunflower plants, their accumulation of aboveground biomass, and the formation of seed yields. High efficiency of foliar feeding of the investigated preparations in all years of cultivation and especially in unfavorable climatic conditions is determined.
