Application of biological preparations and liquid fertilizer-stimulating compositions is a perspective direction of acceleration of growth rates of production of sunflower oil raw materials in soil and climatic conditions of the middle Volga region owing to the following reasons: they stimulate the growth capacity of shoots and accelerate the transition of plants to autotrophic nutrition. As a result, a powerful deep-penetrating sunflower root system is formed, which provides additional sources of food and moisture from such deep layers of soil that are completely inaccessible to cereals; antibiotics produced by biopreparations and chelate form of copper reduces infection of seeds and crops by pathogens of basket and root rot. The number of affected plants is reduced by 35-38% depending on the varietal characteristics of the culture; a positive merger of two factors (additional nutrition and protection of plants from diseases) in one direction is the basis for the formation of highly productive agrocenoses, providing additional production of 0.26-0.27 t/ha of sunflower oil seeds (132-138 kg/ha of vegetable oil).
