In this paper, a thinning experiment aimed at silvicultural and production issues is analysed. The long term experiment was established in a beech stand located in the east part of Slovakia in 1960, in order to find out the effect of low and high thinning on parameters of production. Tending of the stand started at the age of 30 years. Research was conducted in three treatment plots: (i) heavy thinning from below (C grade according to the German forest research institutes from 1902), (ii) free crown thinning according to method developed by ŠTEFANČÍK (1974), and (iii) control plot (without thinning). The basic stand quantitative parameters (number of trees, basal area, and volume of the merchantable timber – the sawlog top 7 cm in diameter, basal area and volume increment, total yield) were evaluated from 12 biometric measurements, which were performed during the 53-year-period of investigation. From quantitative production perspective, the best results were usually obtained in the plot with heavy thinning from below, followed by the free crown thinning. The worst parameters showed the unthinned plot.
