The article presents the results of the application of micro-fertilizers on grafted grape cuttings after grafting in a stratification chamber, as well as the use of foliar treatment on grape grafts planted in a nursery garden. The article provides an assessment of the data on the use of various microbiological fertilizers and the frequency of their use at the output, survival rate and biometric indicators of the development of grape grafts. The Denisovsky technical early variety was used as a scion, and Kober 5BB was used as a rootstock. The research results showed that the lowest yield of 42.9 and 52.7% was obtained in the control option, and the best when using boric acid (B)+ammonium molybdate (Mo)+cobalt nitrate (Co)+copper sulphate (Cu) with a single processing of plants (total element concentration was 0.02%). The survival rate of grafts in the nursery garden was identical to the yield and varied from 35.8% in the control option to 56.5 in the option with B + Mo + Co + Cu at a concentration of 0.02%. The smallest length of the mature shoot was observed in the control option and was 75 cm, which is generally considered not a bad indicator, however, in the option with 0.02% ammonium molybdate, the length of the mature shoot was 95 cm.
