Kovana O. Technological methods of crop and processing products quality improvement of new grapevine cultivars and selections breeded at NSC “Tairov Research Institute of Viticulture and Wine-Making”

For the first time the positive effect of EM-agro on new grapevine cultivars and selections agrobiological and productivity traits breeded at NSC “Tairov Research Institute of Viticulture ans Wine-Making” and on the harvest conditions and physical and chemical parameters of the must from cultivars and selections breeded at NSC “Tairov Research Institute of Viticulture and Wine-Making”, the possibilities of autochthonous wine yeast strains to improve the physical, chemical and organoleptic properties of dry red wines from these varieties were estimated. It was found that treatment with EM-agro improves physical and chemical parameters and organoleptic evaluation of wine materials by increasing the amount of flavonoids, primarily due to increase in the content of proanthocyanidins and anthocyanins, as well as organic acids and terpene compounds.Economic calculations have shown that the EM-agro use on new cultivars and selections makes it possible to obtain additional yields and increase profitability , which determines the feasibility of the developed agricultural method.
