The article considers the analysis of available bibliographic data on the effect of silicon and phosphorus on physiological processes in plants. The aim of the work was to determine the effect of new generation synthetic growth regulators Energia-M and Melafen on the physiological and biochemical parameters and yield of the middle-early Solánum tuberósum cultivar Nevsky, grown on gray forest soil in greenhouse. The effect of growth regulators on the activity of antioxidant enzymes was studied. The observed decrease in the activity of polyphenol oxidase and malondialdehyde is compensated by an increase in catalase and peroxidase, which contributes to the intensity and productivity of the general metabolism in the body of the Solánum tuberósum plant. Analysis of the Solánum tuberósum productivity revealed that the total number and weight of tubers increased in the variants with plant growth regulators as compared with the control, which is associated with the outflow of assimilates into the generative organs.
