In the context of world food crisis, potato production and increasing its yield is an urgent topic of research. In agricultural production, one of the most basic directions of increasing production is the introduction of organic and mineral fertilizers. The purpose of the study is to develop agro-methods for the use of environmentally friendly biopolymers when applying mineral fertilizers for the effective cultivation of potato and to determine production efficiency. To end this purpose, two field experiments and one control variant without the use of biopolymers were used in our study to assess the effect of Nutricharge and Growgreen preparations on the yield of Gala potato variety. To obtain reliable experimental results, several of the following requirements were considered: representativeness, accuracy, and compliance with the principle of single difference. Experiment No. 1 – treatment of ammonium nitrate phosphate fertilizer with Nutricharge at the rate of 3 kg per 1 ha. As a result of the Nutricharge biopolymer application, the biological yield of potato increased by 83.5 c ha-1. Experiment No. 2 – treatment of mineral fertilizers with Nutricharge and Growgreen, 2.5 L ha-1. As a result of the biopolymers application, the biological yield of potato in this experiment exceeds the control data by 237.5 c ha-1. At the same time, the yield in the second experiment turned out to be higher than the yield in the first experiment by 154 c ha-1. An equally important task in conducting this study was to determine, with the help of economic assessment, the production efficiency of biopolymers application. As a result of economic analysis, we found out that the complex use of preparations allowed to reduce the cost of production of 1 ton of potato in the first experiment by 21%, in the second – by 7.7% compared with the control. Cost reduction and revenue increase in the second experiment allowed to make a profit from 1 ha of 298,020 rubles, and in the first – 221,440 rubles. The obtained research data give us reason to say that the use of biopolymers Nutricharge and Growgreen is effective and their scale should be spread throughout the entire region of the country.
