This article deals with the results of the research work concerning the influence of foliar application of grape of Saperavi variety by soluble fertilizers of new generation-Nutrivant plus and Kelik potassiumsilicon. The influence of these fertilizers on yield and actual fruitfulness have also been investigated. The experiments have been carried out both in pureform and in a tankmixture with growth regulator “VIMPEL”. The treatment by these fertilizers has been done three times in the following period; after flowering, in fruit growth phase,(pea-size berry) and in the phase of fruit maturing The foliar treatment in a pure form as well as in a tank mixture led to increase of bunch weight, harvest per bush and the yield capacity of plantation. The influence of fertilizers depended not only on variants of experiment but also on weather conditions of the previous and current year as well as on the previous yield. The negative correlation between the indexes of yield structure of the previous year and the actual fruitfulness of the current year has been revealed. However, the character of these correlative connections depends on many factors and greatly differs according to the year. As a result of these investigations, it was stated that foliar application of Saperavi grape variety by fertilizers of a new generation Nutrivant plus and Kelik potassiumsilicon in a tank mixture with growth regulator “Vimpel” in periods after flowering, berry growth(pea-size berry
) and at the beginning of berry maturing did not promote a stable and significant increase of the main indexes of an actual fruitfulness. The real increase observed in all experimental variants was achieved mainly due to the increase of the average weight of the bunch
