The aim of the study was to determine the effect of foliar fertilizers with the content of macro- and microelements used in the form of chelates on darkening of the tuber flesh of selected potato cultivars. The research was based on a 3-year (2013‒2015) field experiment carried out in Haczów (49°40'N, 21°54'E) on brown, slightly acidic soil. The experiment was based on the method of randomized sub-blocks, where the first order factor was foliar fertilization: Fortis Zn Mn + Fortis Aminotop (A), Fortis B Mo + Ferti Agro (B), Fortis Zn Mn + Fortis B Mo (C) and a standard object without foliar fertilization (0). Second-order factor included four edible potato cultivars of all earliness classes (‘Viviana’, ‘Vineta’, ‘Agnes’, ‘Jelly’). Significant differences in tuber darkening due to foliar application were observed only for tubers 24 h after cooking. The application of Fortis B Mo + Ferti Agro and Fortis Duotop Zn Mn + Fortis Aminotop fertilizers reduced the darkening of the apical part tuber to the greatest extent. Genetic factor differentiated the most the value of all examined traits. The cultivars tested showed varied response to foliar fertilizers.
