An experiment was conducted in a private orchard at Abbasyia, Najaf Governorate during the growing seasons of 2011/ 2012 on fig cv. Waziri. The branches at the age of one year were pruned at level of 25, 50%  and sprayed Grofalcs and Zeatin at concentrations of 250 mg/L for each at 15 March for the tow growing seasons. Results showed that pruning treatments and spraying Grofalcs and Zeatin treatments and their interactions caused a significant increase in GA3, IAA, Zeatin, total chlorophyll in leaves, total yield of tree, total soluble solids, vitamin C and fruit firmness, and decrease in fruit fall, fruit cracking percentage compared with control treatment. There was a significant effect between treatments. Treatment of pruning of branches at the age of one year as 50% + spraying Grofalcs and Zeatin, in concentrate 250 mg/L gave a significant effect and the best results for the two years of the experiment.
