Abstract

Research was conducted in Tekirdag - Yazir village. Merlot/5BB grafting combination in UmurbeyVineyards for determination different tipping periods and different nitrogen doses effect on yield and qualitycharacteristics. Research was conducted in the vegetation period in 2013. In this research four nitrogen doses: Dose1 (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 tippingperiods No Application (NA=Control), Before Anthesis (BA), Full Flowering (FF) and Berry Set (BS) periods wasused. 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 BSperiod yield and quality characteristics (yield 2.87 kg vine-1, total acidity 6.90 g L-1; grape juice pH 3.525) weredesired level for wine grapes. In fertil soil, it were foreseen that, good quality grape growing has been done withoutnitrogen fertilisation.
