Growth and productivity of plum trees depending on the form of the crown and variety

Abstract

In order to reduce the growth vigor of plum trees and increase productivity, it was studied the improved bush crown form. Trees with 3, 4 and 5 main branches took part in the experiment. The control group was presented by the “mixed pyramid” crown that is recommended for plum trees in Moldova. Twelve years of research have shown that the improved bush crown contributes to the rapid development of the vegetative mass of trees when they are young, the reduced size of the crown (by 32-40%) and to almost doubled increased orchard productivity. The most productive was the option of improved bush with 5 main branches.
