The intensification of plum cultivation by introducing multi-leader training systems is based on unifying productive units within the canopy structure, simplifying pruning, and enabling mechanization of certain tasks such as pruning. The aim of this study is to analyze the efficiency of winter pruning in orchards with multileader training systems, specifically UFO and Bibaum. The spindle training system was used as a control. The study was conducted during the winter pruning season of 2023 on the ‘Empress’, ‘Stanley’ and ‘Čačanska Lepotica’ cultivars at the Experimental Educational Center of the Faculty of Agriculture in Banja Luka. The study analyzed the pomotechnical specifics of pruning in the UFO training system, the efficiency of winter pruning, and the amount of discarded material during pruning. The UFO system was better suited for cultivars that predominantly bear fruit on short fruiting wood, considering the reduced pruning volume. The time required for winter pruning was most influenced by the cultivar, followed by the training system. The effective time needed to prune one hectare of plums ranges from 1.7 days (‘Čačanska Lepotica’/Bibaum) to 6.9 days (‘Empress’/UFO). The quantity of discarded material during pruning is primarily influenced by the training system.
