The study was carried out in a cherry plantation established in the spring of 2020 in the north of the country. The object of the research was the variety Grace Star at 4.2x1.8 m spacing and grafted on the rootstock Gisela 6. In order to study different secondary technical operations in cherry cultivation, an experiment was organized in spring 2021 with the following gradation: 1. Trees trained as a slender spindle (control); 2. Solitary incision above the buds and treatment of the cut with water; 3. Solitary incision above the buds and treatment of the cut with the growth regulator Progerbalin LG; 4. Circular incisions on the leader at 25-30 cm from each other and treatment of the cut with Progerbalin LG growth regulator; 5. Extirpation of 4-5 axillary buds from top to bottom of the leader while keeping a bud intact. Tree parameters, the number of branches, average and summed branch length, leaf area, branching angle of branches, the number of solitary flower buds and bunches of may were studied during the research. It was established that to increase the branching potential of the leader, when training cherry trees, solitary incisions above the buds and circular incisions at a distance of 25-30 cm on the leader should be applied and treatments of the cut should be performed with the growth regulator Progerbalin LG in the ratio one part of product to 8-10 parts of latex paint.
