| Abstract | ||
| This research was conducted in a private orchard in Al-Essa region/Al-Kufa/Al-Najaf Al-Ashraf governorate during the growing seasous of 2010 and 2011 to study the effect the spraying the nutrient solution with four concentrations (0, 2, 3, 4) ml/l and salicylic acid with four concentrations (0, 50, 75, 100) ml/l , once in 15/5/2010 and 2011 respectively, on vegetative growth characteristics of Halawani grape variety that breed on wire cabin . Results showed asignificant influence of salicylic acid and nutrient solution on total leaf area of grapevine and bunch, the concentration of total chlorophyll pigment in leaf , total carbohydrates , total nitrogen and C/N ratio in canes ,with these characters being increased as a result of increasing the concentration of both salicylic acid and nutrient solution. The interaction effect of these factors also increased the leaf area of grapevine and bunch , the concentration of total chlorophyll pigment in leaves, total carbohydrates , total nitrogen and C/N ratio in canes. The combination treatment of 100mg/l salicylic acid and 4ml/l nutrient solution gave the best results as compared with the other combination treatments. | ||
