This study was carried out at six years old Italia (Vitis vinifera L.) grape cultivar grafted on 1103 Paulsen rootstock in a vegetation period of 2017 in Selçuklu district in Konya province. In the research the effects of Dose 0 (Control) (0 ml TKI-Humas / 5 liter water), Dose 1 (167 ml TKI-Humas / 5 liter water), Dose 2 (333 ml TKI-Humas / 5 liter water), Dose 3 (500 ml TKI-Humas / 5 liter water), Dose 4 (667 ml TKI-Humas / 5 liter water) applications on grape yield and quality of Italia grape cultivar were investigated. According to the findings the highest grape yield obtained as 4,81 kg/vine with Dose 2 and 4,57 kg/vine with Dose 4 applications; the highest cluster weight was 380,13 g with Dose 2 application; the highest 100 berry weight was 518,85 g with Dose 2, 498,50 g with Dose 4 and 497,03 g with Dose 3 applications; the highest maturity index was 30,44 with Dose 0 application; the highest grape juice yield was 706,67 ml/kg with Dose 4 application were determined. To increase the fresh grape yield, cluster weight and 100 berry weight, it can be recommended on Dose 2 (333 ml TKI-Humas / 5 liter water) application in Italia grape cultivar.
