Abstract: This study was carried out to evaluate the impact of biofertilizer and cultivar on vegetative potential (height of the plant, number of crowns and leaves per plant, and the area of a single leaf), leaf mineral composition (micro- and macroelements), yield potential (number of inflorescences and fruit set per plant, yield per plant, and yield per square meter), fruit characteristics (mass, length, width, and fruit shape index), and chemical traits (soluble solids content, titratable acidity (TA), vitamin C, total anthocyanins (TACY), total phenolic content (TPC), and total antioxidant capacity (TAC)) in the fruits of Clery, Joly and Dely strawberry plants. Two types of biofertilizer were applied: Biofertilizer 1 (inoculums of the mixture of liquid bacteria cultures of the genera Azotobacter, Derxia, and Bacillus) and Biofertilizer 2 (inoculums of liquid culture of diazotrophic bacteria belonging to the genus Klebsiella). The applied biofertilizers made a significant impact on the parameters of vegetative potential and contents of some macroelements and microelements in the leaf, as well as the values of TA, TACY, TPC, and TAC. Cultivar demonstrated a significant impact on plant height and the number of crowns in it, leaf macroelement and microelement content, generative potential parameters, and morphometric and chemical fruit parameters.
