Abstract Literary sources of domestic and foreign researchers, concerning the effect of one of the efficient farm practices, namely, fertilization, on the productivity of the intensive apple-tree plantations, were presented. The issue of the short-term and continuous application of fertilizers was studied, that is, major (soil) fertilization and additional top dressing. Based on the carried out analysis it has been found out that at present no definite recommendations as to the application of fertilizers in the industrial apple-tree plantations are available, in particular under their repeated cultivation on the place of the uprooted plantations. There is no data concerning the rates of the soil fertilization and the phases of the application of top dressing with macro- and micro-elements in the plantations of the various cultivar-rootstock combinations. Fertilizers applied to the soil or foliar have a positive effect on the growth and overall productivity of apple orchards. Currently, various doses, terms and methods of applying fertilizers in different soil and climatic conditions are being studied. The issue of studying the impact of soil fertilization and foliar feeding of intensive apple tree plantations depending on varietal rootstock combinations in specific soil and climatic conditions remains relevant. The reviewed literary sources do not provide a complete answer to the question of the effect of fertilizers, especially for foliar feeding of apple trees, on the growth, development, productivity and chemical composition of leaves and fruits. Therefore, there is a need for further study of these issues, in particular, in research on the development of an optimal fertilization system in non-irrigated apple plantations on medium-sized rootstocks, which determines the relevance of the work Hence, the issue of the rational fertilization and additional nutrition of the intensive apple-tree plantations of various cultivar-rootstock combinations in correlation with the construction of the plantations is relevant, and it requires a thorough investigation. Also there is a necessity to scientifically explain the issue of the varietal farm practices in horticulture.
