Abstract

Increasing the yield and quality of potatoes is one of the most important tasks of potato industry. A promising method of increasing the productivity and quality of potatoes is to use microbiological preparations. Their action is due to the use of the properties of microorganisms that can transform the elements of soil nutrition from forms inaccessible to plants to assimilable ones. Consequently, it can be concluded that the study of potato productivity on the dark gray forest soil using the microbiological preparation Biocomposite-correct is an actual area of research. The results of the conducted research show that the used preparation Biocompositecorrect had a positive effect on the elements of the crop structure and potato yield.The optimal rate of application of the preparation Biocomposite-correct (3.0 l/ha with a working fluid flow rate of 400 l/ha), was determined in the course of the experiment. On average, the maximum increase of the mass of potato tubers from one bush was observed in the variant with the use of Biocomposite-correct in the dose 3.0 l / ha (+ 387.1 grams), which is 92.2% more compared to the control, where the maximum yield was 24.2 tons/ha.
