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), number of petals per flower (32.40), number of flowers per plant (116.98) and total yield per plant (0.73kg). However it was minimum in control.
