In order to investigate the effect of application methods of ZnSo4 on qualitative, quantitative and correction of zinc deficiency in grapevine, an experiment was conducted in completely randomized block design with 10 treatments and 4 replications. Treatments included control, trunk injection three levels 1.5, 3 and 5 g/l, spray in three levels 1.5, 3 and 5 g/l and soil application (Soil drench) in 75,150 and 200 g/vine. Results showed that highest yield 17.81 and 16.39 kg/vine was obtained in soil application of 200 gr/vine and trunk injection in 1.5 g/l, respectively as compared to control with 7.27 kg/vine. Trunk injection in 3 g/l concentration increased the berry volume to 3.62 cm3 as compared to control plant. All of treatments increased chlorophyll content as compared to control. Also, maximum zinc concentration in leaf was observed in vine’s sprayed with 5 g/l with 127.43 mg/kg dry matter as compared to control with 17.5 mg/kg dry matter. So, the maximum yield was obtained in low concentration of ZnSo4, but optimal concentration of zinc in leaf was observed in plant was sprayed with 1.5% ZnSo4.

Abstract
The aim of this study was to eliminate Zn deficiency and increasing yield in Grapevine (Vitis vinifera L) cv, Askari، via trunk injection method. The experiment was carried out in the Cisakht region; in randomize complete blocks design with four treatments and four replications. Treatments included of Zinc trunk injection in concentration 0.15, 0.3 and 0.5% amount of 500 cc was injected to each vine and Control. Injections were applied in three stages including flowering, after fruit set and veraision. Different traits including yield, chlorophyll, Zn concentration in leaves, TSS %, TA, length, volume and weight of berry were measured. Results showed that trunk injection of zinc increased yield, Chlorophyll, length, volume and weight of berry when compared with untreated control. The TSS %, Zn concentration, TA and ratio of TSS/TA were not affected by trunk injection. However Zn was increased in leaves up to 16.7%. So, trunk injection method in order to correct zinc deficiency and increasing yield in Grapevine cv, Askari، is recommended.
Key words: Grapevine, Askari Cultivar, Zn So4 Trunk injection, Yield, Chlorophyll
