Compatibility of clonal rootstocks with grafted variety samples, as well as their agronomic performance and high productivity in commercial orchards are among the most pressing issues today and form the basis of intensive horticulture. The following planting materials were used for the research: rootstocks M9; M26; Pajam-1 (dwarf) and M4; MM106; PB-4 (medium-sized), differing in growth strength. The plants were planted in one row, the distance between rows was 0.70 cm, the distance between plants within a row was 0.20 cm. The studied rootstocks were grafted in triplicate onto zoned and promising apple varieties Golden Delicious, Champagne Reinette and Azerbaijan. To study the degree of compatibility and quality of the resulting planting material, various indicators were used: Fertilizers and physiologically active substances were used in the system of agrotechnical measures carried out during the growing period before grafting. In the Guba-Khachmaz region, MM106 grafting with Fon + 0.3% Novosil is recommended on medium-sized rootstocks. The yield of the Reneti Champagne variety was 20.8 t/ha. In the Guba-Khachmaz region, clonal rootstocks are grafted using the Pizham-1 method onto dwarf rootstocks with Fon + 0.1% Novosil, along with fertilizers and physiologically active substances.
