The present investigation entitled “Effect of plant growth regulators on growth, flowering, yield and vaselife of chrysanthemum under Prayagraj agro climatic conditions”, was carried out during August to December, 2022, in Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was conducted in Randomized Block Design with ten treatment combinations, with application of three plant growth regulators Brassenosteroid(BA), Triacontanol(TRIA) and Gibberellic acid(GA3) each of 50ppm, 100ppm and 150ppm, which was replicated thrice. It was concluded that the plant growth regulators rendered their significant effect on almost all the growth, flowering and yield characters of chrysanthemum. The treatment, T9- GA3@150ppm was found superior in terms of plant height (72.47cm), plant spread(35.33cm), number of branches(11.67), leaf length(9.03cm), days taken for first flower bud initiation(66.30 days), days taken for 50% flowering(113.43 days), number of flowers per plant (48.53), flower diameter(10.20cm), stalk length(13.58cm), duration of flowering days(66 days), flower yield per plant(206.67g), flower yield per hectare(229.63q), vase life of flower(16.33 days). Among the different treatments the highest Gross return is 918,520Rs/ha, Net return is 620,343.35Rs/ha, benefit cost ratio is 3.08 was obtained from the treatment, that is T9-GA3@150ppm.
