The present investigation entitled “Effect of different plant growth regulators and their levels on floral yield and vase life of China aster [Callistephus chinensis (L.) Nees] cv. Shashank” was under taken at Department of Horticulture, Naini Agriculture Institute, Sam Higginbottom university of Agriculture, Technology and Sciences (SHUATS), during the year 2016-17 with thirteen treatments which replicated thrice in a Randomized Complete Block Design. The treatments comprising of GA3, NAA, CCC and their different concentrations along with control. The results of the study revealed that floral attributes like maximum flower diameter (6.21 cm), flower weight (5.5 g), flower yield per hectare (12.58 t) was observed from the plants grown in plots receiving GA3 @ 200 ppm. Among the treatments applied the minimum duration for bud initiation (51.67), minimum days to flowering (65.86) with maximum vase life (9.0 days) were recorded in CCC @ 1500 ppm. However maximum days taken to bud and flower initiation was recorded in control. Thus, it can be concluded that application of GA3 @ 200 ppm can be recommended for commercial cultivation of China aster cv. Shashank.
