We have established the importance of proper vine pruning techniques depending on individual grape variety characteristics and its influence on crop formation and quality of the grapes. The technique of studying the influence of the length of the vine pruning on the qualitative indices of the fruit of the grapes has been proposed. Field research was carried out in 2014-2016. Agricultural technology in the experiment is commonly used for forest-steppe. The vines are planted on the plot without irrigation, the shape of the shrubs is harp multy sleeved with a knot of substitution, sheltered on a vertical trellis of 1.5 m heigh. The methods that can be used to increase the yield of grape varieties in the Poltava region (Ukraine) have been analyzed. It has been established that the coefficient of fructification of apical buds predominantly correlates with the actual yield, which allows to use this link to predict yields by grape varieties. The justification and characterization of the selected methods of vine pruning, which would ensure the obtaining of high sustainable yield and fruit quality, as well as the economic efficiency of growing grapes, have been given.
