This study was carried out on own rooted 7 years old Superior Seedless (Vitis vinifera L.) table grape variety in a vegetation season of 2015 in Ahmetli district. The experiment was completely randomized block design with 7 treatment combinations replicated in three blocks. When all treatments was used at fruit set, GA3as 10 ppm dosage used for elongate cluster (when cluster length reached 7-8 cm). Control (C) only water was sprayed. The aim of this study was revealed effects of applications on grape yield and some quality characteristics of Cluster Tipping (CT), Girdling (G), CT+G, GA3+CT, GA3+G, GA3+G+CT. It was found that all applications generally had statistically (P<0.05) significant effects on grape yield, cluster weight, cluster width, berry length, berry width, berry length/berry width, soluble solid and titratable acidity in Superior Seedless. The highest grape yield, cluster weight, cluster length were obtained in GA3+G, the highest berry weight, the longest berry length were obtained in G, the highest soluble solid value were obtained in GA3+ CTR+ G and GA3+G respectively. As results of this study, general recommendation is made of GA3+G the most suitable application for growing Superior Seedless table grape variety.
