Abstract: This study was conducted Ismailoglu grape type (Vitis
vinifera L.) and its vine which was aged 15 was grown on its own
root in a vegetation period of 2013 in Nevşehir province in Turkey.
In this research, it was investigated whether the applications of
Control (C), 1/3 cluster tip reduction (1/3 CTR), shoot tip reduction
(STR), 1/3 CTR + STR, TKI-HUMAS (TKI-HM) (Soil) (S), TKIHM
(Foliar) (F), TKI-HM (S + F), 1/3 CTR + TKI-HM (S), 1/3 CTR
+ TKI-HM (F), 1/3 CTR + TKI-HM (S+F), STR + TKI-HM (S), STR
+ TKI-HM (F), STR + TKI-HM (S + F), 1/3 CTR + STR+TKI-HM
(S), 1/3 CTR + STR + TKI-HM (F), 1/3 CTR + STR + TKI-HM (S +
F) on yield and yield components of Ismailoglu grape type. The
results were obtained as the highest fresh grape yield (16.15 kg/vine)
with TKI-HM (S), as the highest cluster weight (652.39 g) with 1/3
CTR + STR, as the highest 100 berry weight (419.07 g) with 1/3
CTR + STR + TKI-HM (F), as the highest maturity index (44.06)
with 1/3 CTR, as the highest must yield (810.00 ml) with STR +
TKI-HM (F), as the highest intensity of L* color (42.04) with TKIHM
(S + F), as the highest intensity of a* color (2.60) with 1/3 CTR
+ TKI-HM (S), as the highest intensity of b* color (7.16) with 1/3
CTR + TKI-HM (S) applications. To increase the fresh grape yield of
Ismailoglu grape type can be recommended TKI-HM (S) application.
