Effects of Some Applications on Yield and Yield Components of Tilki Kuyruğu Grape Variety

This study was conducted on grownTilki Kuyrugu grape variety (Vitis vinifera L.) in Mersin province in Turkey in 2016. The cultivar is 12 years old and grown on their own roots and evaluated as table. The effects on yield and yield components were researched of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), Humic Substance (HS), 1/3 CTR+STR, 1/3 CTR+HS, STR+HS, 1/3 CTR+STR+HS applications in Tilki Kuyrugu grape variety. The results were obtained as the highest fresh grape yield were (9.86 kg/vine) with 1/3 CTR and (9.77 kg/vine) with HS applications; the highest cluster weight were (328.78 g) with 1/3 CTR, (325.56 g) with HS, (309.89 g) with 1/3 CTR+STR and (305.11 g) with STR applications; the highest 100 berry weight was (512.89 g) with STR application; the highest maturity index was (57.12) with STR+HS application; the highest must yield were (730.00 ml/kg) with 1/3 CTR+STR, (723.33 ml/kg) with HS, (710.00 ml/kg) with STR, (693.33 ml/kg) with 1/3 CTR+HS and (693.33 ml/kg) with STR+HS applications. 1/3 CTR and HS applications can be increased fresh grape yield. Additionally, 1/3 CTR, STR, HS and 1/3 SUK + SUA applications can be increased bunch weight in Tilki Kuyruğu grape variety.
