Abstract
This study was carried out during growing season of 2014 on 18 years old grapevine cv. Tri-rash at a private vineyard located near Shar-Bazher town, Sulaimani governorate, Iraq in order to study the foliar spraying of three concen- trations (0 , 0.2 and 0.4%) of magnesium, number of sprays and their interactions on yield and quality of grapevine. The results indicated that the interaction treatment of foliar application of 0.4% Mg and three sprays significantly increased leaf area, leaf fresh and dry weight, Leaf chlorophyll content with the values of 131.50 cm2, 2.859 g, 1.062 g and 45.02 SPAD respectively, as soon as the highest cluster weight, (473.75g, number of berries per clu1sters (197.55) and yield per vine (16.65 kg) were recorded from the mentioned treatment combination
