This study was conducted at the ‘Integrated Farm’ of the International Anjel Association, Voluntary Organization of Japan, Konabari, Gazipure during the period of 10 November-30 January 2018, Bangladesh to find out the better performance of GA3 treatments doses on tomato variety Ratan. Data were collected on plant height, leaves number, fruits number per plant, fruit weight per plant, ascorbic acid and total soluble solids (Brix) regarding five levels of gibberellic acid viz. 20  ppm (T1), 40 ppm (T2), 60 ppm (T3), 80 ppm (T4) and 100 ppm (T5) beside T0 which represents the control. The experiment was arranged in a randomized complete block design with three replications. Application of GA3 at 100 ppm caused an increase in plant height (50.30 cm), leaves number (50), fruits number (29.50 per/plant), fruit weight (1.52 kg/plant),  ascorbic acid (1.80 mg/100gm) and total soluble solids (4.10 Brix) among the different treatments of GA3.

Keywords: Gibberellic acid (GA3), Tomato, Yield, Quality, Bangladesh.
