In this article, data is given on the results of an experiment on the use of mineral fertilizers - nitrogen, phosphorus and potassium for two-year forest crops of the Sivers apple tree in a hot and dry climate in the summer in the low-mountain zone of the spur of the Chatkal Range of the Western Tien Shan. The content of nitrate and ammonia nitrogen and mobile assimilable forms of phosphorus and potassium in the soil layer to a depth of 1 m and the content of these elements in apple plants for two years after fertilization were studied in dynamics.

mineral fertilizers, macronutrients, soil moisture, mobile forms of nitrogen, phosphorus and potassium, closed root system, seedlings, microflora, control, soil horizon, western and southern slope, survival rate.
