In this study, which was carried out during the vegetation period of 2021 in ‘Table Grape Varieties Application and Research Vineyard’ in the ‘Plant Production Research and Application Unit of COMU Dardanos Campus, Faculty of Agriculture’ the effects of different summer pruning applications on berry set characteristics, yield and quality of ‘Atasarısı’ grape variety were investigated. In the research, on vinestocks of the cultivar; control (CNT), topping (TP), lower leaf removal (LLR), axillary shoot removal (ASR) and topping + lower leaf removal + axillary shoot removal (TP+LLR+ASR) applications were carried out. Two for each summer shoots with two clusters were selected in the vinestocks of each application, and flower bud counts were made in the clusters before flowering and berry counts were made in the clusters after the grain set. According to the research findings; the highest number of berry set in the 1st and 2nd clusters and their averages were obtained from TP+LLR+ASR (116.60 number cluster⁻¹; 105.80 number cluster⁻¹ and 111.20 number cluster⁻¹, respectively) and ASR (99.17 number cluster⁻¹; 103.83 number cluster⁻¹ and 101.50 number cluster⁻¹, respectively) applications. The highest ratio of berry set in the 1st and 2nd clusters and their averages was determined in the TP+LLR+ASR (31.93%; 39.32% and 35.62%, respectively) application. It has been determined that the applications of ‘Atasarısı’ grape variety have a direct effect on the berry set and thus on the cluster compactness, berry width, berry length and berry weight parameters. Especially, the average yield, which was 3576.9 g vinestock⁻¹ in CNT, increased to 5692.9 g vinestock⁻¹ in TP+LLR+ASR application, but with the increase in average yield, the maturity index value, which was 36.63 in CNT, decreased to 26.80 in TP+LLR+ASR application.
