In recent years, the viticulture industry, and the problems of producers of grape products have attracted more attention from the state and the public in terms of its contribution to GDP growth. Productivity and longevity of grape plantations directly depend on the quality of the planting material. Therefore, the relevance of research to obtain the highest yield of standard seedlings of valuable table grapes (Yubilei of Novocherkassk, Dubovsky pink, Bogatyanovsky, Vera) is undeniable. Two variants of biostimulators of growth have been studied: amino peptide agrochemical and a complex mean of chitosan and succinic acid in comparison with background fertigation. The highest yield of seedlings of the first grade level 71-76 % of the open ground nursery on light chestnut soils obtained by its cultivation with a three-time application of foliar fertilizing of amino peptide mean of biological origin Isabion at a dose of 2 l/ha with the addition seedlings output relative to the control 10-13% and the level of production profitability from 135 to 151 %.
