This article discusses the methods and standards for the use of complex high molecular fertilizer StresStop on potatoes in the conditions of the Akmola region. The article deals with the influence of the complex high molecular fertilizer StresStop on the yield, marketable qualities and biochemical composition of potatoes, depending on the norms of its application and the phase of development of potato plants. During the phase-by-phase treatment with StresStop fertilizer, at the doses recommended by the manufacturing institutions, the content of dry matter, starch and vitamin C in potato tubers changes, while the content of toxic elements in potatoes does not change significantly. A significant effect of a complex high molecular fertilizer on potato yield was determined. The greatest increase in the potato yield +9.1 t / ha in comparison with the control variant was provided by spraying the variant treated with 0.01% StresStop solution in the full germination + flowering phase, where the yield was 17.5. The use of a complex high molecular fertilizer contributes to an increase in the yield, commodity and quality indicators of potatoes, while the study showed that the content of toxic elements in potatoes does not change significantly
