Contents of mineral elements Mg (a), K (b) and total antioxidant capacity determined by FRAP method (c) in onion bulb mass. Treatments: Ctrl—Control, M1—the mix of Glomus sp. (G. intraradices BEG140, G. mosseae BEG95, G. etunicatum BEG92, G. claroideum BEG96, G. microaggregatum BEG56, and G. geosporum BEG199), M2—G. intraradices BEG140, S—saprophytic fungi preinoculated bark chips (Gymnopilus sp. IZO24, Agrocybe praecox AER1, Marasmius androsaceus MAN1), S + M1, S + M2. Means ± SD, columns marked with the same letters are not significantly different at the level 𝑃<0.05, Tukey HSD Test, 𝑛=7.
