The present investigation was conducted in the screen-house of the Department of Horticulture, College of Agriculture, CCS Haryana Agricultural University, Hisar during the two successive seasons of 2011–12 and 2012–13 to evaluate the effect of biofertilizers (Azotobacter and Azospirillum) and different levels of nitrogen (0, 10, 20 and 30 g/m²) on flowering parameters of chrysanthemum cv. Dolly Orange. Maximum number of flowers per plant (28.00 and 32.00) were recorded on the pots receiving Azospirillum + 20 g/m² nitrogen in the year 2011–12 and 2012–13, respectively. The interaction between levels of nitrogen and biofertilizers on flower size was found to be non-significant in the year 2011–12, but it was significant in the year 2012–13. Maximum flower size (4.60 cm) was obtained in treatment combination of Azotobacter and 20 g/m ² nitrogen. The maximum fresh weight of flower (2.11 and 2.10 g) was recorded with Azospirillum in combination of 20 g/m ² nitrogen in both the years, respectively.
