Results of biennial comparative study of features of formation of a phenolic complex V. angustifolium and species hybrids (V. angustifolium × V corymbosum) Northcountry and Northblue in field experiment cutover peatland on a hydrothermal regime against entering full mineral and domestic microbial fertilizings of MaKlor, AgroMik and Baktopin at the differentiated and joint application to contrast seasons in article are introduced. In the weather environment of a growing season close to centre perennial norm, tested agricultural practices promoted expressed in different degree, depending on a genotype of plants and a kind of the fertilizings, to primary depletion of fruits of a blueberry by tannins and bioflavonoids. It is shown that complete dressing promoted accumulation magnification in fruits of a blueberry of the reduced bunches of polyphenols (leucoanthocyanids and catechins) and inhibited accumulation of the acidifyed forms (actually anthocyans and flavonols). Hot and dry weather promoted enrichment of fruits of a varietal blueberry by tannins, and V. angustifolium – flavonols, and also to their depletion the anthocyanin pigments and catechins. For cultivars Northcountry and Northblue primary activization of biosynthesis the anthocyanin pigments, the most significant against fertilization is shown. It has caused augmentation of their relative lobe as a part of the Р-vitamin complex, especially at joint entering of drugs of AgroMik and MaKloR into 10%-s’ concentration.
