The research objective was to reveal effective prep-arations stimulating the growth, increasing productivity of eggplants, but not influencing the accumulation of nitrates in them. The research problems were to estab-lish the dynamics of growth of vegetative bodies, for-mation of productivity of technically mature fruits of egg-plants and their quality. The object of the research was the hybrid of eggplants of F1 Valentin. The research method was field experiment. The scheme of the exper-iment included options: 1) control - plants without pro-cessing; 2) control - spraying by water; 3) "Agricola"; 4) sodium humate; 5) "Zircon". The research place was the South of the Amur Region. The most intensive growth of stalks, branches and leaves was noted for the option "Agricola", conceded to this option processing by "Zircon" a little, then processing option of humate of sodium followed and the smallest indicators the control option - without processing was characterized in weather conditions of 2015-2017 the maximum produc-tivity of technically mature fruits of eggplants was re-ceived in experiment option "Agricola" - 28.3 t/hectare, and control option conceded to it on 4.7 t/hectare. All studied preparations provided reliable increase in productivity in comparison with control: "Agricola" - for 20.9 %; "Zircon" - on 15.8 and the humate of sodium for 12.8 %, and on the average mass of commodity fruit according to experiment options - for 8.9 %; 16.7 and 22.7 %. All studied stimulators increased the resistance of eggplants to stressful factors of vegetative period in hot droughty 2015 and damp cold 2016 growth regulat-ing substances - important element of technology of cultivation of eggplants increasing productivity and quality of fruits, but not promoting high accumulation of nitrates.
