Introduction. The contradictory picture of the modern development of agro-agricultural production predetermines the need for the development of new methods, adapted to the current conditions of land use. The inclusion of plant growth regulators in the complex of agrotechnological measures will increase the stimulating effect on the plant, growth activity, physiological functions and protective reactions of the body associated with increased metabolism, stress resistance to adverse conditions

... seases, pests, frost, drought, etc.) the results of studies on the effect of growth regulators on obtaining a guaranteed yield of high quality tomato. Object. The object of the study was a hybrid tomato Fokker F1. Plant growth regulators -Energia-M, Bioduks against the background of N250P100K125 application. Materials and methods. Studies conducted in laboratory and field experiments (IP Zaitsev V.A. Gorodishchensky district, Volgograd region) in the period from 2014 to 2019 were carried out according to the «Methodology of field experience in vegetable growing». Results and Conclusions. It was proved that the studied preparations Energia-M and Biodux stimulated the growth and development of plants, increased the productivity of tomato in severely arid conditions of the Lower Volga region. The productivity potential of the Fokker F1 hybrid tomato was obtained using the option with pre-sowing seed treatment, as well as foliar treatment of plants during the period of growth and development with Energia-M and Biodux. It is recommended for manufacturers of high-quality vegetable products to widely use these preparations against the background of sufficient mineral nutrition by soaking the seeds before sowing and processing plants during the growing season.
