This research was carried out to determine the effect of gibberellic acid (GA3) and benzyladenine (BA) application on yield and quality components (multiplication ratio, flower stem length, flower diameter, vase life, flower stem diameter,) of gerbera. Three different levels of GA3 (125, 250, 500 ppm) and BA (100, 200, 400 ppm) were applied by foliar spray. Compared to BA application, GA3 applications gave good results on yield and quality parameters. The maximum yield was obtained by 125 ppm of GA3 application. It was found that 500 ppm of GA3 application most effective on stem length and flower diameter. On the other hand, it's determined that 400 ppm BA application significantly increased stem diameter and multiplication ratio. Its concluded that, the GA3 and BA demonstration interference in growth characteristics of gerbera plant.
