Abstract: The investigation was carried out at C-Block farm, kalyani, Bidhan Chandra Krishi Viswavidyalaya during 2015-16 in chilli cv. Beldanga to study the effect of gibberellic acid on growth and yield parameters in chilli. During seedling stage, roots are dipped with different concentrations (0, 10 and 20 ppm) of gibberellic acid and transplanted, which were further sprayed with gibberellic acid (GA3) of three more concentrations (20, 30 and 40ppm) at flowering stage. The experiment was laid out in RBD with three replication. Among different treatments maximum plant height (64.10 cm), plant spread (63.83 cm in East-West and 62.67 cm in North-South) and number of primary branches (8.65) at 150 DAP was found with 20 ppm seedling dip and 40 ppm foliar spray followed by 20 ppm seedling dip and 30 ppm foliar spray. In respect to the yield parameters, Early fruit maturity (38.13 days), maximum yield (152.64 g plant-1), maximum number of fruits plant-1 (84.67), maximum fruit weight (2.61 g) and maximum fruit set (30.15%) was observed in 20 ppm seedling dip and 40 ppm foliar spray followed by 20 ppm seedling dip and 30 ppm foliar spray.
