Abstract: The present investigation on “Effect of organic manures and biofertilizers on growth, flowering and flower yield of rose (Rosa hybrida L.) cv. Gladiator†was conducted at Department of Horticulture, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat) during Rabi season in the year of 2016 -17. Different treatments were significantly affected on the growth, flowering and flower yield parameters. It is evident that significantly maximum plant height (98.50 cm), plant spread (64.86 cm), number of branches per plant (7.20) and stem diameter (1.18 cm) at peak flowering stage were recorded with Castor cake @ 0.8 kg + Azotobacter @ 1 ml + PSM @ 1 ml + KSB @ 1 ml / plant. Similarly, significantly the minimum average days to first flower (37.95), maximum average days to flowering span (118.18), diameter of flower (7.58 cm), number of petals per flower (72.55), stalk length (30.03 cm), stalk diameter (0.30 cm), number of flowers per plant (64.83), number of flowers per plot (324.15), number of flower per hectare (4.32 lac), flower yield per plot (5.82 kg) and flower yield per hectare (7753.66 kg) were recorded with Castor cake @ 0.8 kg + Azotobacter @ 1 ml + PSM @ 1 ml + KSB @ 1 ml / plant. As per economics point of view, treatment consisting Castor cake @ 0.8 kg + Azotobacter @ 1 ml + PSM @ 1 ml + KSB @ 1 ml / plant was found maximum gross realization (Rs. 8.64 lac ha-1) and net return (Rs. 5.39 lac ha-1) but the highest cost benefit ratio was obtained under the treatment consisting Farm yard manure @ 4 kg + Azotobacter @ 1 ml + PSM @ 1 ml + KSB @ 1 ml / plant (1:2.70). Overall it can be concluded that Castor cake @ 0.8 kg + Azotobacter @ 1 ml + PSM @ 1 ml + KSB @ 1 ml / plant was found superior for growth, flowering and yield of rose.
