Abstract The aim of the research was to determine the factors influencing the formation and implementation of productivity of apple varieties in the conditions of the Ukrainian Steppe. The research was conducted in 2017–2020 in the intensive apple plantation of the Neophyte Farm, a branch of the Department of Fruit Growing and Viticulture of the Uman National University of Horticulture. The objects of the research were the apple varieties: Golden Delicious (control), Fuji, Red Chief, Florina and Jonagold, grafted on the M.9 rootstock and planted in 2014 according to the 3.5 x 1 m scheme. The results of research on the productivity of apple trees of Golden Delicious, Red Chief, Fuji, Florina and Jonagold varieties in intensive plantations grown in the Steppe of Ukraine were considered. Establishing intensive apple plantations requires a high-quality selection of varietal composition. The full realisation of the productive potential of apple trees in certain conditions is possible only if environmental factors correspond to the biological characteristics of varieties, so the study of their influence on the rational placement of apple plantations and selection of varieties will help to increase the efficiency of fruit production. The results of the research showed that during period of research the maximum number of ovaries was found in the plantations of Florina variety, which was 1.8 times higher than the minimum value found in the trees of Fuji variety. The highest yield during the study period was recorded in the plantations of Jonagold and Florina varieties, which was 1.3 and 1.1 times higher than the value of the control variety Golden Delicious. The maximum yield of plantations was recorded in 2018 with the advantage of the Jonagold variety – 40.8 t/ha.
