%X The aim of the study was to examine the effects of potassium at different concentrations on the growth of black pine seedlings. The study was carried out with 1+0 black pine seedlings of Afyonkarahisar-Ah£¿rda£¿£¿ origin grown in polyethene container filled with perlite in Eski£¿ehir Forest Nursery. The seedlings were grown using different nutrient solutions with potassium concentrations of 0-23-35-47-100 and 150 ppm. Nutrient concentrations, root-collar diameter, height, root length, number of lateral roots, and dry weight of the seedlings were determined. Data were evaluated by ANOVA and Kruskal-Wallis test. According to results of the statistical analyses, potassium doses impacted on seedling height, root-collar diameter and number of lateral root. The tallest and the thickest seedlings were produced with 23 ppm potassium nutrition while the highest lateral roots with 100 ppm. As a result, it is possible to raise the afforestation success in arid and semi-arid regions by producing potassium-fed black pine seedlings with higher, thicker root-collar diameter and a higher number of lateral roots
