Abstract

The article highlights the generalized research data of the Department of Horticulture, Viticulture, Biology and Chemistry of Odessa State University. The main direction of its work is to maintain the productivity of existing plantations and the formation of high-yielding plantations of grapes of technical varieties in the Northern Black Sea region of Ukraine. Based on many years of research, the productivity of vineyards of Aligote, Traminer pink, White fetish, Chardonnay, Pinot Noir, Cabernet Sauvignon and many others has been established, as well as complex schemes of impact on young grape bushes and plantations older than 25 years. As a result of researches, the basic optimum terms for conditions of the South of Ukraine in which it is necessary to carry out processing by growth stimulators and root and foliar feeding are established. These terms are: the first treatment before flowering, the second when the berries reach the size of a pea and the third at the beginning of ripening berries. It is proved that the after-effect of application of fertilizing elements is intensified on old plantations after the renewal of the plantation and can last up to three years, depending on the wet supply of the territory. The main conclusions and proposals for the use of complexes of agricultural technology elements based on root and foliar nutrition with different substances, irrigation, periodic deep tillage is given. Based on the obtained results, a mathematical model of quality management of grape products and products of its processing is developed

Highlights

  • The grape plantations in Ukraine are very different in quality both in the condition and age

  • In our point of view, such tools of influence are the replantation of the grape plants with fertilization to a considerable depth and foliar and root nutrition of grape plants with biologically active exo- and endogenic substances with a strict interpretation of varietal agriculture

  • Since 2001, the Department of Viticulture and Winemaking in various farm types of the Odesa and Mykolaiv Region (Southern Ukraine) has laid a number of experiments: 1. During 2001-2005, in the agricultural production cooperative “Limanskii”, Ochakovskii Region, Mykolaev Oblast carried out Experiments on the productivity of grape plants influenced by the microelements complex nutrition (Ni, Cr, Mn, Ti) on Chardonnay and Pinot noir on the plantations starting between 3 and 7 years

Summary

INTRODUCTION

The grape plantations in Ukraine are very different in quality both in the condition and age. For the revival of viticulture, along with the laying of new highly productive plantings, it is necessary to prolong the life of existing ones and improve their productivity and ensure the quality of the obtained products At this stage, it is possible to resuscitate the existing grape plantations only through the combined effect on the above-ground and below-ground parts of the grape plant. Unconventional physiologically active substances, namely organic acids of the Krebs cycle, amino acids, pyridine compounds have been proposed in order to achieve these objectives at the Department of Viticulture and Winemaking of the OSAU [21] For solving this problem, firstly, we should grow high-quality grafted planting material, so that the plants have the same vigor and productivity after planting the vineyard. It is possible to improve the quality of wine materials in the process of their production via selecting yeast strains by various technological methods before, during and after fermentation (Fig. 1)
