The paper presents the results of the impact made by genotype ('Clery', 'Joly' and 'Dely'), fertiliser and harvests on the content of anthocyanins (ACY) and total phenols (TPC) in the fruit of strawberry in 2014. Two types of fertiliser were applied - mineral NPK fertiliser and microbiological fertiliser. Fruit samples for analysis were collected in five harvests, in the full maturity phase. The obtained results have shown that the content of ACY and TPC was under a significant impact of the genotype, fertiliser, harvests and the interaction of these factors as well. Fruit of cultivar 'Joly' had the highest ACY and TPC. In addition to this, significantly higher values of ACY and TPC were recorded with the use of the microbiological fertiliser, compared to the mineral fertiliser. Strawberry fruits harvested in the second half of the harvesting season had a significantly higher total phenols content compared to the fruits harvested at the earlier stages of the season. Based on the obtain...ed results, it can be concluded that the biggest advantages related to both tested parameters (ACY and TPC) were recorded in the interaction between the 'Joly' cultivar, microbiological fertiliser and fourth harvest. In addition to this, certain amounts of mineral fertiliser can be replaced with microbiological fertiliser in order to obtain healthy and environmentally-safe products.
