Abstract

The study was conducted to determine the most effective concentration of Gibberellic Acid (GA3) that promotes fruit setting and fruit development as well as the flower development that is most responsive to GA3 The cost and benefit analysis of the treatments was also done. Seven concentrations (O, 5, 10, 20, 40, 80, and 160 ppm) were sprayed to the flower clusters during pre-anthesis and post-anthesis. The study was laid in a 2x7 factorial experiment replicated three times, each with five hills per replicate. Fruit setting was highest in tomato plants sprayed with 10 ppm GA3 during post-anthesis. Applying five ppm GA3 during pre-anthesis or post-anthesis significantly improved tomato production among other treatments based on yield and return on investment (ROI) The cost and benefit analysis showed that applying GA3 was not costly and gave more than 200 % ROI in treated tomatoes.
