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 above-ground 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. The yield of sunflower seeds in the control variant was 2,55 tons per hectare, but due to the use of additional fertilizers, the yield increased to 2,61-2,46 tons per hectare, which corresponds to an increase in the range from 8,3 to 39,3%. The maximum level of productivity was achieved under the condition of using Architect at a dose of 1,2 l/ha in the phase of 3-4 pairs of leaves and during budding. The calculation of the economic efficiency of the conducted experimental studies and hybrids showed that the hybrids have a sufficiently high profitability, but the greater increase in net profit was provided by the LG 50505 hybrid.
