The paper presents evaluation of the effect of two intensities of winter pruning on cropping and fruit quality of sour cherry cv Oblacinska. With 4 x 2 spacing and pyramidal crown as training system, light pruning, including removal of suckers and vigorous and upright shoots, and severe pruning, including removal of vigorous branches and considerable thining of bearing trees, were employed. It was established that the increase of pruning intensity leads to increase in fruit size of sour cherry cv Oblacinska and its fruit ratio. Soluble solids content of the fruit is very high and remains the same after pruning, whereas the total acids content markedly increases in case of severe pruning. Severe pruning causes substantial yield reduction per unit of arable land and decrease in yield efficiency defined as relation between yield quantity and annual growth of trunk cross-sectional area. However, yield efficiency defined as yield quantity per unit of crown volume adequately increases with more intensive pruning. Intensity of pruning is not an important factor as regards regularity of fruit set.
