The present investigations were undertaken at experimental farm of department of Floriculture and Landscaping, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during the years 2012-2013. The China aster cv. ‘Kamini’ was selected for conducting the investigations. The experiment was laid out in RBD (Factorial) with 20 treatments and 3 replications. Tallest plant (83.32 cm) obtained with a combined application of 30 g N/m2 and 25 g P2O5/m2 (N2P3) that proved to be at par with N2P1, N2P2 and N4P3 whereas minimum plant height (46.42 cm) recorded in plants without nitrogen and phosphorus dose (N0P0). A combined dose of nitrogen and phosphorus significantly improved the plant spread. Maximum plant spread (76.00 cm) found in those plants with a combined dose of 30 g N/m2 and 25 g P2O5/m2 (N2P3) and proved to be significantly higher over all other treatments. Maximum number of branches per plant (7.01) recorded with 30 g N/m2 (N2) that proved superior over other treatments including control (N0). Largest leaf area (21.72 cm2) found with a combined application of 30 g N/m2 and 25 g P2O5/m2 (N2P3) and it proved to be at par with N3P1. However, minimum leaf area (9.82 cm2) recorded in plants supplied with 40 g N/m2 and 25 g P2O5/m2 (N4P3).
