Abstract
An experiment was carried out at College of Horticulture, UHS campus, Bengaluru during 2016-17. The experiment was laid out in a Randomized Complete Block Design (RCBD) comprising of eight treatments and three replications. Treatment detail includes micronutrients viz., MgSO4, MnSO4, FeSO4, Boron, ZnSO4 and CuSO4 at different levels on growth, yield and quality of floribunda rose cv. Mirabalis. Results revealed that foliar application of T7- ZnSO4 (0.75%) + Boric acid (0.5%) + FeSO4 (1.5%) + MgSO4 (0.5%) + MnSO4 (1%) + CuSO4 (0.3%) at 210 days after pruning. Results revealed that increased in plant height (73.61 cm), plant spread (N-S direction) (64.00 cm), E-W direction (50.32 cm), number of shoots per plant (14.83), shoot length (61.27 cm), leaf chlorophyll content (51.22), more leaf area (3.61 cm2). Among flowering, yield and quality parameters, early bud initiation (28.60), early first flowering (37.58), flower diameter (4.23 cm), increased flower stalk/petiole length (3.99 cm), number of petals per flower (32.40), less physiological loss of weight (25.47 g), highest number of flowers per plant (116.98), higher flower yield per plant (295.72 g), 100 flower weight (253.12 g), maximum total flower yield per plant (0.73 kg), flower yield per hectare (16.22 tonnes), shelf life (41.93 hrs.), and also B:C ratio (3.3), However it was minimum in control.
