Abstract: The experiment was carried out at Horticulture Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. Treatment consisted of foliar application of GA₃ (200, 250 and 300 ppm) and SA (100, 150 and 200 ppm) along with control (distilled water) in the rose plant grown under protected condition. Experiment was laid out in a Randomized Block Design with four replications. Both GA₃ and SA treatments significantly affected the growth and flowering parameters of rose cv. Taj Mahal. Among all the treatments, application of GA₃ 300 ppm is most effective treatment for increasing plant height at 60 DAS, number of leaves per plant at 60 DAS, number of leaves per branch at 45 DAS and number of branch per plant. Similarly, minimum days to first bud initiation, maximum bud length, bud diameter, number of petals per flower, petals length and petals breadth was also recorded with GA₃ 300 ppm.
