The aim of the study was to evaluate the Scots pine production and growth characteristics in different site conditions given by the affiliation of the inventory plots to ecological series and forest vegetation altitudinal zones (FVAZ). Tree measurements from the second cycle of National forest inventory (NFI) were used as input data. The evaluation was based on static growth models of diameter at breast height, tree height and volume of mean stem. Scots pine has the greatest production potential on variohumida series, the potential of acid sites is lower compared to the trophic sites. Based on the volume of mean stem at the age of 100 years, the highest production potential of pine stands is on humid sites and in the 4th FVAZ. The observed age of culmination of average volume increment indicates that the optimal age of quantitative felling maturity is in some cases lower than the age of felling maturity derived from the site index curves of valid yield tables. Acceleration in the volume growth was observed for the young stands up to 50 years of age. For more information see Summary at the end of the article.
