This study was carried out to evaluate the impact of the genotype and fertilizer on fruit quality of strawberry cultivars ‘Clery’, ‘Joly’ and ‘Garda’. Three types of fertilizer were applied: M ‡ mineral fertilizers, M+B - combination of microbial and mineral fertilizers, B ‡ microbial fertilizer. Fruits of ‘Garda’ had significantly higher fruit weight, firmness and titratable acidity (TA), whereas fruits of ‘Joly’ expressed significantly higher antioxidative capacity compared to the other two cultivars. In all fertilization treatments, fruits of ‘Clery’ had a high content of soluble solids (SSC), total sugars (TS) and inverted sugars (IS). Among the tested cultivars, ‘Garda’ can be recommended for more intensive commercial growing because of early ripening time and satisfied outer and inner fruit quality. Taking into account the positive effect of combined application of mineral and microbiological fertilizers on content of soluble solids, total acids, total and invert sugars in the fruit, a partial substitution of mineral fertilizer by biofertilizer could be recommended in nutrient management of strawberries aiming to improve the nutritional fruit quality.
