It is known that the use of advanced agrotechnical measures based on the soil and climate conditions for the cultivation of tree-like plants in nurseries gives good results. During the cultivation of seedlings, the demand for water and nutrients is different in different phases of the plant. Due to this, in the course of our research, agrotechnical measures were applied to seedlings based on plant and soil requirements during the phases of growth and development. Applied agrotechnical measures are mainly aimed at maintaining soil moisture and sufficient supply of nutrients, and these factors are of particular importance in the growth and development of plants. It can be seen from the obtained data that in the case where mineral fertilizers P30K30 kg/ha were used, the height of the seedlings was 92.0 cm, the diameter of the root part was 7.2 mm, mineral when fertilizers N30P30K30 kg/ha are used, these indicators are respectively 95.1 cm and 7.8 mm in diameter, when mineral fertilizers N60P30K30 kg/ha are used, respectively, 101.0 cm and It is equal to 9.8 mm.
