Abstract

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 %.

Highlights

The total demand of Russian Federation winegrowers in planting material for the purpose of planting new and reconstructing old plantations is from 10 to 20 million pieces per year
The survival rate of cuttings at the background level of mineral nutrition was at the level of 50.5 %, the use of the root formation stimulator Ruther Bio contributed to an increase in the number of rooted cuttings by 11.3 %
We studied the percentage output of seedlings of the first class of valuable table varieties-Yubilei Novocherkassk, Dubovsky pink, Bogatyanovsky, Vera in comparison with the zoned variety Kodrianka that has been grown in the Low Volga region for more than 30 years

Summary

Introduction

The total demand of Russian Federation winegrowers in planting material for the purpose of planting new and reconstructing old plantations is from 10 to 20 million pieces per year. The volume of self-rooted seedlings is from 5 to 15 % of the total demand. The search for effective ways to increase root ability and output of standard seedlings of valuable grape varieties remain ns an urgent task for the region's grape nursery branch and management. This increases the output of seedlings and contributes to the rational organization of labor in farms engaged in nursery [1, 2, 3]
