Abstract: The aim of the study was to assess the polyphenol content in tubers of three edible potato cultivars depending on the biostimulants used. Field research was carried out in the years 2016–2018 with an application of biostimulants in individual farm in Poland. The experiment was led by means of a split-plot method. The impact of two factors was tested. The first-order factor were the three cultivars of edible potato: Jelly, Honorata, Tajfun, while of the second–order four variants of applying biostimulants: Kelpak SL, Titanit, GreenOk, BrunatneBio Złoto. Potato plants were treated with biostimulators three times (beginning of flowering, full flowering and after plant flowering). The polyphenol content was determined by spectrophotometric method with Folin–Ciocâlteu reagent in fresh potato tuber mass. The content of polyphenols in tubers depended on the cultivars and biostimulants. Among the studied cultivars, Jelly accumulated the most polyphenols and Tajfun the least. Biostimulants increased the concentration of phenolic compounds compared to tubers from the control treatment.
