The problem of finalizing the optimal productive parameters of the architecture of the fruit plantation in various cultivation conditions is considered one of the most priority in all countries with advanced nut cultivation. Research in the field has shown that climate change affects the physiology, phenology of species, the composition and dynamics of communities in biocenoses, productivity, fruit quality, etc. As trees age and fruiting intensifies, the intensity of vegetative growth, including that of extending the framework, decreases. At the same time, the possibility of replacing exhausted semi-skeletal branches with new ones is reduced. Measurements of annual branches were made at the end of the growing season according to the experiment scheme. The research was conducted in a 16-year-old walnut orchard of the Franquette variety in the center of the country. Contour cuts were performed in the spring until the start of vegetation, from 2.5 to 3.5 meters from the center of the crown. Following contour cutting of walnut trees of the Franquette variety, the walnut harvest decreased from 15% in the control variant compared to the V2 variant to 29% in the V4 variant. The number of fruits in one kilogram decreased depending on the degree of contour cutting performed in each variant according to the experimental scheme.
