During 2018 and 2019 seasons to investigate the effects of foliar spraying six chemical compounds namely GA3 at 10 ppm, hydrogen peroxide (H2O2) at 10 mM, salicylic acid at 5%, Mepiquat chloride at 200 ppm, micronutrients at 0.1% and free amino acids at 0.1% on some vegetative growth, yield and physical and chemical characters of the berries. Supplying the vines with any one of chemical compounds three times during season was accompanied with enhancing some vegetative growth, yield and fruit quality compared with the control treatment. The best of chemical compounds on some vegetative growth characters was GA3 spraying, followed by micronutrients, H2O2 and salicylic acid. As for the yield and cluster weight and dimensions the best of chemical compounds were salicylic acid spraying which it significantly surpassed all the rest of treatments followed by micronutrients and then MC and free amino acids. The corresponding increment percentage for these treatment was found to be 48.24, 33.30, 25.59 and 24.51 % over the control , respectively.
The results of different plant extract spraying on quality of berries demonstrated that salicylic acid, amino acids and H2O2/ the previous results of the current study suggested that spraying three times with salicylic acid at 5% recorded the best results concerning the productivity and quality parameters.
