This study carried out at agricultural experiments and researches station, collage of agriculture, university of Kirkuk, Iraq. During the growth season 2017 to study effect of GA₃ foliar application with three levels (0 , 100 and 200) mg L^-1 and urea with three levels (0 , 2000 and 4000) mg L^-1 and the interaction between them on some green growth characteristics of olive young tree Picual cultivar. The results can be summarized as:
 

The foliar application with 100 mg L^-1 of GA₃ had significant effect on (height and stem diameter, leaf number, leaf area, number and height of branches, chlorophyll index) and the dry weight percentage didn't affect with GA₃.
The foliar application with 4000 mg L^-1 level of urea leads to significant increase in all the growth characteristics.
The interaction between the factors had significant increase in all growth characteristics specially 100 mg L^-1 of GA3 and 4000 mg L^-1 of urea.
