The study aimed at analysing the radial and basal area growth of mixed forests in regard to growth and stands conditions. Field measurements were carried out at the forest management unit Leskova dolina site. Altogether 12 research plots were selected, 7 of them on slopes and 5 on ridges. From the centre of each plot the distance, inclination and azimuth in relation to the vertices for all the trees were measured. Moreover, the diameters and heights of trees were measured and their social status was determined. From every tree on the plot the increment core for the last 10 tree rings was taken using Pressler%s borer, while for the 15 dominant trees (5 spruces, 5 firs, 5 beech trees) per plot the cores were taken to the pith. Stand densities were higher on ridge stands, while the growing stock on these stands was lower in comparison with the slope stands. Radial and basal area growth decline in all tree species with aging. Radial growth was bigger on stands with higher growing space per tree, while basal area growth was lower in such areas. Radial, as well as basal area growth on the stands decreases with increasing the share of the beech, while the effect of silver fir share was the opposite. The highest radial growth for all analysed tree species was recorded for predominant trees. On the contrary the highest relative basal area growth for beech and spruce was recorded in suppressed trees, while as regards fir the lowest relative basal area growth was indicated for the predominant trees. Stands on ridges exemplified lower radial as well as basal area increments compared to slope stands.
