Productivity formation features of Apple trees (Malus domestica Borkh.) with intermediate insertion of low-growth rootstock EM-IX in the Crime

The long-term results of studies on the formation of productivity in apple trees on the medium-sized rootstock MM-106 with an intermediate insert of a low-growth rootstock EM - IX are given. The objects of research are cultivars: Golden Delicious, Jonagold, Kimmeriya, Krymskoe with a planting pattern of 3.5 x 1.25 m and 3.5 x 1.75 m. Trees are formed according to the type of free spindle. As a result of the research, a high potential application of the combined stock (with intercalary insert) in the garden, which provides early fruiting, a rapid increase in yield, high marketability and keeping quality of fruits, is revealed. Domestic intensive gardens on a combined stock can be created in the conditions of the Crimea without any support, which saves material resources for their laying. The formation of trees according to the type of free spindle in the gardens makes it possible to compact the planting of trees in a row by 20-25% and reduce the amount of labor expended on pruning trees and harvesting 1.6 times, depending on the cultivar. Realization of the productivity potential in such gardens is determined by the high level of agricultural technology with the obligatory implementation of technological methods.
