Abstract: The objective of this study was to examine the effect of Paclobutrazol on vegetative growth of olive tree. Paclobutrazol (PBZ) as potent specific inhibitor of GA3 biosynthesis. Paclobutrazol slightly decreased the length of the plant height. Leaf area reduction by paclobutrazol was also reported and suppressed plant spread also. PBZ with 4ml a.i plant-1 was found to be the most effective in suppressing the vegetative growth of the plant. Paclobutrazol has been reported to increase yield of fruit trees. Found no PBZ influence on flowering of olive tree during my research work which may due to immaturity of the plant and unsuitability of the climatic condition.
