All treatments used significantly increased the yield per vine than the control during the two seasons of study. The vines treated with (CPPU) 2.5 or 7.5ppm and GA₃ at 20, 10, 20ppm gave the higher yield compared with the treatments. These increments reached about 92-94 % and 94-96 % respectively than the untreated vines used during the two seasons. The untreated vines showed higher values in bunch compactness than all treatments used during the each seasons 1997 and 1998. Whereas, the rachis weight gave higher values for the all treatments used compared the control. All treatments used significantly increased both of berry and juice volume than the control especially, Sitofex at 2.5 or 7.5ppm in combination with GA₃ at 20, 10, 40ppm. All Sitofex and GA₃ applications used significantly increased berry length and diameter, than the control. All treatments used significantly reduced T.S.S. than the control but the acidity took the opposite trend to those found with T.S.S.. Whereas, T.S.S/acid ratio took similar trend to those found with T.S.S.
