The paper deals with analysis of the results of 38-year-old research on oak stands tended by non-whole-area method. The stand originates from natural regeneration, with the age of 50 and/or 53 years, situated in permanent research plot (PRP) Veľká Stráž I, located at an altitude of 330 m a.s.l., SW exposure, management complex of forest types 208 – beech-oak forest on loess, management complex 25 – fertile beech-oaks. PRP consists of three partial plots: on the first plot (A I), there are established 156 growth areas calculated per hectare, with square form (3 x 3 m) with area of 9 m2. The second plot (A II) numbers 204 growth areas calculated per hectare, with circle form (diameter 4 m), and/or area of 12.57 m2. The third plot is control one (without tending). From the viewpoint of qualitative and quantitative production, more suitable results were achieved on plot managed by non-whole-area tending with circle growth areas (diameter 4 m) in comparison with the plot consisted of growth areas of square form (3 x 3 m). Number of trees per hectare at the age of 50 and/or 53 years found on plot A I was 122 individuals and on plot A II 230 ones, respectively.
