The research aimed to standardize the sowing dates for different varieties of China Aster in the Raipur region of Chhattisgarh Plains during the Rabi season of 2022-23. The experimental design utilized a Completely Randomized Design (CRD, Factorial) with 16 treatment combinations, consisting of four varieties (Phule Ganesh Violet, Phule Ganesh Purple, Phule Ganesh Pink, and Phule Ganesh White), along with four sowing dates (20^th November, 30^th November, 10^th December, and 20^th December).

The results indicated that among the interaction between sowing dates and different varieties of China Aster, it was observed that V₂D₂ had the maximum plant height (70.0), V₃D₂ exhibited the maximum number of leaves (68.0), and V₄D₂ showed the maximum plant spread (32.6 cm). Regarding flowering parameters, V₃D₂ demonstrated early flowering (37.4 days), the highest number of flowers per plant (52.1), flower size (5.8 cm), flower yield per plant (180.8 g), and vase life (12.9 days). Additionally, V4D2 had the longest flowering duration (56.0 days).
