This study was carried out during growing seasons of 2012 on 14 years old Taifi grapevine in a private vineyard located at Atrush, Nineveh governorate, Kurdistan region, Iraq, in order to study the effect foliar application of three concentration of Mammoth (0, 1 and 2 ml.l-1), three concentrations licorice root extract (0, 3 and 6 g.l-1) and their interaction.

Results indicated that foliar application of 2ml.l-1 Mammoth and 6 g.l-1 licorice root extract significantly increased leaf area, leaf dry weight, leaf chlorophyll content, as soon as number of clusters per vine, cluster weight, yield per vine, Total soluble solid %.

And total sugar %.

Whereas the same concentrations significantly reduced total acidity % in the berry’s juice.
