A field experiment was conducted in Międzyrzec Podlaski, (51°59’ N and 22°47’ E), Poland in the period from 2015 to 2017. The experiment was a two-way random split-plot arrangement of plots with three replicates. The following factors were examined: three varieties of potato – Honorata, Jelly, Tajfun, and four variants of application of biostimulants (Kelpak SL, Titanit, GreenOk, BrunatneBio Złoto). The control object comprised potato plants sprayed with distilled water. Biostimulators were applied to potato plants three times (beginning of flowering, full flowering and after flowering of the plants). The aim of the study was to determine the effect of biostimulants on the content and uptake of zinc and copper with the yield of potato tubers. High amount of rainfall in 2017 contributed to an increase in the content of zinc and copper in potato tubers. The tubers of potatoes treated with BrunatneBio Złoto had the highest contenting uptake of Zn and Cu compared to the control plants. The content of microelements in the tubers was significantly dependent on the genotype. The highest concentrations of Zn and Cu were found in the Honorata tubers, and the largest uptake was observed in the Jelly variety.
