| description | The paper presents data on a three-year study (2020-2022) of the effect of a liquid-phase biological product containing iron nanoparticles (LPB-Fe), obtained by biosynthesis using green tea extract, on the yield of potatoes of the Skarb variety and the activity of soil enzymes under the conditions of Tverskaya areas. Comparative efficiency of LPB-Fe, the original LPB biopreparation, solution of iron nanoparticles Fe NPs was studied in the field against the background of NPK application. The results showed that the maximum productivity (669.1 g/bush) of potatoes was obtained by foliar treatment of vegetative plants with a 1% solution of LPB-Fe – 16.9 % more than the control variant (NPK background). With the separate use of a 1% solution of LPB and a 1% solution of Fe NPs, the productivity was 628.4 and 550.6 g/plant, respectively, which indicates an increase in their impact on potato plants when used together as part of LPB-Fe. It was noted that the activity of invertase correlated with the content of humus in the soil, and the activity of the protease correlated with the content of readily hydrolysable nitrogen. In addition, the study of the activity of enzymes in the soil under potatoes (catalase, dehydrogenase, invertase, cellulase and protease) showed that they have a significant impact on the yield of potatoes at different stages of the growing season with various technological methods of using biological preparations. For example, when treating potato tubers at the seedling stage, an inverse relationship was found between catalase activity in the soil and yield: the higher the enzyme activity, the lower the yield (correlation coefficient is -0.82). And in the case of cellulase, with the same technological method, on the contrary, a direct dependence is observed: the higher the activity of the enzyme in the soil at the seedling stage, the greater the yield (correlation coefficient is 0.72). Thus, when soil and plants are exposed to Fe-containing biological products, the activity of enzymes responsible for the transformation of the main biogenic elements (carbon and nitrogen) and redox processes occurring in the soil changes, which ultimately leads to a change in soil fertility and, therefore, either decrease or increase of crop yields.method, on the contrary, a direct dependence is observed: the higher the activity of the enzyme in the soil at the seedling stage, the greater the yield (correlation coefficient is 0.72).
