The response of 5 levels of N (100, 150, 200, 250 and 300 kg/ha) and 4 levels of P (0, 100, 150 and 200 kg/ha) was studied in China aster cv. ‘Kamini’. The maximum plant height (51.91 cm), plant spread (21.27 cm), length of flower stalk (27.27 cm) and number of flowers/plant (35.22) were obtained with highest level of N application @ 300 kg/ha. Though application of N @ 200, 250 and 300 kg/ha was statistically at par with each other for above 4 important parameters. Rest of the parameters e.g., number of days taken for 100% flowering, diameter of flower and weight of 5 flowers were not significantly influenced by graded levels of N. Vegetative growth and floral parameters were not significantly influended by graded levels of P. The graded levels of N and P did not significantly influence the postharvest quality of cut flowers. The interaction between N and P levels was non-significant for all parameters.
