The paper describes the results of the application of wastes from the production of alcoholic beverages (wine yeast, vinasse and grain mashes) on the productivity and quality of agricultural production. It was established that the application of wine yeast at the rate of 13-26 t/ha provided an increase in grape production (Sauvignon) on an average for seven years of 1.4-2.3 t/ha. The harvest increase at the incorporation of the vinasse in the dose of 300-600 m3/ha was on average for seven years of 0.7-0.8 t/ha. Grain mashes in the dose of 47-94 m3/ha resulted in average crop increase for six years of 1000-1400 kg/ha of grain units. It was found that fertilization with wastes from wine factories has not diminished the quality of the obtained wines. The physico-chemical composition is in line with the requirements for quality wines. The researched wines are distinguished by good organoleptic qualities (7.8-7.9 points) and according to the typicality they correspond to normative acts. The applied grain mashes helped synthesize and accumulate crude protein in grains. The total protein gain collected in six years was 1140-1320 kg/ha.
