The results of the research of the effect of seeds pre-sowing treatment with a complex of preparations, including protectant, microelements and growth regulators on economic and biological characteristics and properties of sunflower hybrids F1 Borey and F1 Dariy under conditions of the southwestern part of the Central Black Soil region are presented. The effective pre-sowing treatment scheme for seeds of sunflowers hybrids F1 Borey and F1 Dariy was determined, which allows us to obtain a seed yield up to 29.03 c / ha (increasing 6.6 c / ha) with a profitability level of 156.4% (increasing 39.6%).
