Abstract

This scientific article provides experimental material devoted to the study of the influence of varietal characteristics of peach and schemes for placing trees in the garden, using weak vegetatively propagated rootstocks. Experiments have shown that an increase in the density of peach distribution in the orchard grown on the VSV-1 rootstock contributes to a reduction in the crown volume from 16.99 to 9.15 m3 / v., The VVA-1 rootstock - from 16.99 to 9.15 m3 / v. ., rootstock GF-667 - from 16.25 to 7.94 m3 / v. The same pattern persists in the formation of the projection and saturation of the crown with leaves. However, in terms of 1 hectare of the garden, the value of these signs increases 1.9-2.3 times.Growing a peach of the Lola variety on weak vegetatively propagated rootstocks VSV-1, VVA-1 and GF-667, with thickened placement of trees in the garden 5.0x2.0 meters, allows you to receive a net profit from the use of the new technology in the amount of 89.929 - 94.917 million soums / ha, with the cost of fruit production 299.2-315.4%.
