The article presents the results of studying the impact of different options for cutting fruit vines on the growth and productivity of shoots of the grapes. The obtained experimental data indicate the excessive overload of vines with eyes and shoots when performing contour trimming bushes without normalizing the choice of shoots, in comparison with other variants of experience. A significant increase of eyes on the vines when performing contour cutting was because during this method of cutting, the cutoff is at a certain level all the shoots are horizontal on the arm vines. A big load of vines shoots when performing contour cutting has reduced the length of shoots at 48 – 51%, and leaf area developed on the shoots of 53 – 54%. While the lowest productivity was different shoots developed on the vines in 3 variant, because here the contour cutting vines was not accompanied by a subsequent breaking of superfluous shoots, which have overloaded the bushes shoots. At the same time, contour cutting vines with subsequent breaking of the normalizing excess shoots were allowed to grow for fruiting the bushes a sufficient amount of normally developed shoots with high productivity and good quality bunches
