AB  - This article shows the results of determining the effect of bio-organic-mineral fertilizers on the accumulation of Pb, Cd, As, and Hg and on the quality, yield indicators of potatoes treated by plant development stages. According to the results of laboratory analysis, the qualitative and quantitative content of dry matter, starch, nitrates, vitamin C, lead, cadmium, arsenic, and mercury isolated from extracts treated with bio-organic-mineral fertilizers was determined. The effect of two bio-organic-mineral fertilizers and the stage treatment by these fertilizers on the content of dry matter, starch, nitrates, vitamin C, Pb, Cd, As, and Hg in potatoes of Nevsky variety was studied. It was shown that the bio-organic-mineral fertilizers have a slight impact on the content of toxic elements in potato tubers and, therefore, on the quality of the product based o-n them. When treating potatoes at the stages of full sprouts + flowering + budding with BioZZ solution and at the stages of full sprouts + flowering + budding with WORMic solution, in which an increase of quality indicators of potato tubers was observed, favorable effect of bio-organic-mineral fertilizers on potato productivity was observed. The data of this study reflect a specific pattern that bio-organic-mineral fertilizers can increase the marketability, improve the quality and productivity of potato seeds, and have a positive effect on potato safety.
