 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 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 (73.47cm), plant spread (67.47cm in East-West and 67.67 cm in North-South) and number of primary branches (9.13) at 150DAP was found with 20 ppm seedling dip and 30ppm foliar spray. In respect to the yield parameters, maximum yield (181.37 g/plant) and maximum fruit set per cent (34.61) was observed in 10 ppm seedling dip and 40 ppm foliar spray (34.61) followed by 20 ppm seedling dip-30 ppm foliar spray (34.17). Early fruit maturity (40.33 days), maximum number of fruits (87.80), fruit length (72.73 mm) and fruit width (35 mm) was observed in the plants treated with 20 ppm seedling dip and 30 ppm foliar spray. best yield was obtained from the plots sprayed with 10 ppm seedling dip with 40 ppm foliar spray, 20 ppm seedling dip with 20 ppm foliar spray and 20 ppm seedling dip with 30 ppm foliar spray.

Key words: chilli, gibberellic acid, growth, yield.
