Objective: This study was performed to determine the effects of two girdling practices on yield and some pomological properties of persimmon trees in 2019. Material and Methods: The gridling practices were applied to Hachia variety, common in Çanakkale, as single girdling, double girdling and control. Girdling treatments were performed after full blossom in full yield trees. Fruit yield and some pomological properties of the variety were determined. Fruit weight, fruit width, fruit size, fruit skin colour (L, a, b), pH, titratable acidity (TA) (%), fruit flesh firmness (kg / cm2) and total soluble solid content (TSS) were determined. Results: The highest yield per tree was obtained from the control (120.74 kg tree-1) treatment. The largest fruits with a value of 383.23 g were obtained from double girdling treatment. The double girdling application provided the highest values in terms of fruit length and fruit width (79.22 mm, 94.71 mm, respectively). There was a significant difference (p<0.05) between applications in terms of total soluble solid content. Conclusion: The girdling treatments significantly increased fruit weight, fruit size and total soluble solid amount in “Hachiya” variety.
