Currently, the level of utilization of the biological potential of sunflower is the lowest among oil crops and does not even reach 50%. The introduction of new hybrids with high adaptive potential and the use of modern cultivation technologies can ensure a high level of efficiency in sun-flower production by increasing yields with optimal sowing areas. The studies showed that the studied sunflower hybrids produced an average yield, and the LG 50635 hybrid produced the maximum yield of 2.12 t/ha, significantly exceeding the control variant. The use of the Sunflower biocomplex contributed to obtaining a higher yield, which was: for the DG 5555 hybrid - 2.27 t/ha, for the LG 50635 hybrid - 2.41 t/ha, for the LG 50479 CX hybrid - 2.31 t/ha.
