Summary: The results of our research made it possible to recommend for production certain agrotechnical methods of sunflower cultivation technology, which, in the conditions of insufficient moisture in the Vinnytsia region, allow obtaining sunflower yields close to the level of the genetic potential of hybrids based on resource conservation and optimization of energy consumption. Additional feeding of growth regulators affected the accumulation of above-ground biomass in sunflowers. The greatest increase in above-ground biomass in comparison with the control group was observed in the year with unfavorable weather conditions. The maximum values of aboveground biomass in sunflower plants were reached at the end of the flowering phase when applying two-time spraying of sunflowers in the phase of 3-4 pairs of leaves and budding and were from 1205 to 1350 grams per one plant, compared to 980 grams per plant in the control version of the experiment. When growing sunflower hybrids LG 50505 and LG 50585, the maximum area of the leaf surface of 4631-4687 cm2 was formed by crops against the background of the use of the Architect restregulator. Growing sunflowers using Kalm`s restregulator in the 2023 season led to a decrease in the leaf surface area of plants of both studied hybrids.
