Research was conducted in Tekirdag - Yazir village. Merlot/5BB grafting combination in Umurbey
Vineyards for determination different tipping periods and different nitrogen doses effect on yield and quality
characteristics. Research was conducted in the vegetation period in 2013. In this research four nitrogen doses: Dose
1 (Control) (0 kg da-1 N), Dose 2 (5 kg da-1 N), Dose 3 (10 kg da-1 N) and Dose 4 (15 kg da-1 N) and; also four tipping
periods No Application (NA=Control), Before Anthesis (BA), Full Flowering (FF) and Berry Set (BS) periods was
used. Yield characteristics (estimated yield per vine) and quality characteristics (SS, TA, pH, sugar concentration,
sugar amount per berry, total anthocyanins, TPI, total tannins) were examined in this trial. As a result; tipping in BS
period yield and quality characteristics (yield 2.87 kg vine-1, total acidity 6.90 g L-1; grape juice pH 3.525) were
desired level for wine grapes. In fertil soil, it were foreseen that, good quality grape growing has been done without
nitrogen fertilisation.
