The effect of pruning on length of the fruiting branches, distribution of male and female florescence as well as yield of three hazelnut cultivars (Istrian Long, Roman and Tonda Gentile delle Langhe) have been studied. The experiment has been carried out at the experimental field Radmilovac premises of the Faculty of Agriculture, Belgrade - Zemun (Serbia). Pruning exhibited considerable effect on all evaluated parameters. Acquiantance with the zones of formation of male and female flowers is of major importance for adequate application of pruning. Zones in which both male and female flowers mostly occur largely coincide in the fruiting branches of the same length. Fruiting branches up to 10 cm length should never be cut, as by the removal of the terminal and the initial nodus 85% of the fully formed female flowers on respective branch would be eliminated. Differences in fruit weight between pruned and unpruned bushes ranged from 4.35% to 10.99%, whereas yield differences were about 20%.
