Abstract: Special production practices can be used to enhance yield and overall fruit quality. Trunk and branch girdling are known among those practices applicable to some wooden fruit species. For Chinese date (Ziziphus jujuba Mill.) girdling was a common practice in traditional orchards with the aim to increase the fruit set. Short and deep wounds were usually made with an ax in the tree bark and phloem around the trunk. The paper presents the effect of girdling applied at the beginning of the flowering season on tree trunk and lateral branches. The girdled jujube trees increased their yield by improving fruit set, enlarged fruit size and advanced fruit maturity. Girdling effect was notable for some genotypes: larger fruit size by 3 to 5 mm in diameter, earlier harvest by 3 up to 10 days and reduced number of pickings at harvests. Varietal response to this practice, however, was quite variable. Preliminary results showed that the varieties response to girdling was substantial in some and almost unnoticeable in others.
