Abstract:
The present study on “Effect of biostimulants and biofertilizers on quality and yield of Floribunda roses was undertaken during the year 2020-21 at College of Horticulture, Bengaluru. The experiment was laid out in Factorial Randomized Block Design with three replications. The biostimulants were sprayed at bimonthly interval on cvs. Mirabel and Charishma. Among the treatments, the highest flower diameter (5.45 cm), stalk length (3.94 cm) was registered when Seaweed extract @ 2000 ppm (T7) sprayed on cv. Charishma. The highest number of flowers per cluster was recorded in Ecohume 3 ml/l (7.11) with cv. Mirabel. The highest 100 flower weight was recorded in Ecohume 3 ml/l (277.42 g) with cv. Charishma. The maximum number of flowers/plant (325.77), flower yield/plant (687.99 g) and per hectare (4.25 t) was also recorded in Ecohume 3 ml/l with cv. Mirabel and shelf life of flowers (42.22 hr.) was highest in T7-Seaweed extract @ 2000 ppm in cv. Mirabel. This study indicated that foliar application of Ecohume at 3 ml/l at bimonthly interval to the plants exhibited superior yield and foliar application of Seaweed extract @ 2000 ppm performed best for quality in Floribunda roses
