The study was undertaken to investigate the effect of foliar application of different micronutrients (B, Zn & Fe, 0.5%, 1.5% and 1%, respectively) on plant growth and flowering of three rose (Rosa hybrida L.) cultivars viz. Kardinal, Amalia and Rosy Cheeks. Nutrients were applied alone and with different combinations after 6, 8 and 10 weeks of pruning. Plant height, number of leaves per branch, leaf area, number of flowers plant', flower stalk length and leaf Zn contents were maximum with B + Zn application followed by only B application which also resulted early flower production as compared to rest of the treatments while bud diameter, flower diameter, as well as fresh & dry weight of flowers were maximum with B application alone followed by combination of B + Zn application. Leaf chlorophyll contents, Flower quality, flower stalk diameter and Leaf B & Fe contents were highest when plants were sprayed with combination of all micronutrients.
