PhD of Agricultural Sciences, аssociate рrofessor of the Department of Forestry, Landscape Gardening, Horticulture and Viticulture of Vinnytsia National Agrarian University Abstract The article presents the main studies and their results on the influence of soil nutrition on the growth and development of seedlings of the pedunculated oak in the botanical garden of VNAU. The study of the soil fertility effect and the influence of nutrient content on the seedlings condition is the main component of the successful cultivation of forest plantations of pedunculated oak in Vinnytsia region. As a result of the conducted researches it was revealed that the average increase in height of oak seedlings on control made 4.1 cm for 2 months (+55% of the initial). Feeding oak seedlings with the investigated preparations contributed to the increase of the average growth of seedlings from 0.8 cm (+11% compared to the control) to 2.1 cm (+22.4% compared to the control). Analysis of the dynamics of the oak seedlings root neck average diameter during the 1st year of life was characterized by lower relative growth rates due to 2-months fertilization. Thus, under control (without fertilizers) the diameter of the root neck for the same period increased by 0.065 cm (+29.5%) whereas on plots where fertilizers were applied, the diameter increased by 0.087-0.147 cm (+38.5% - + 64.5%). Keywords: common oak, seed material, soil nutrient regime, growth, soil extract. Introduction.
