Abstract: A field experiment entitled “Response of golden rod (Solidago canadensis L.) to planting time and GA₃” was carried out during kharif season of the year 2018-2019 at Satpuda Botanic Garden, Horticulture Section, College of Agriculture, Nagpur (Dr. PDKV, Akola), M.S. (India). The treatments comprised of four planting time viz., 15^th June, 15^th July, 15^th August and 15^th September and three GA₃ concentrations viz., control i.e 0 ppm, 200 ppm and 250 ppm GA₃. The experiment was laid out in Factorial Randomized Block Design replicated thrice. The results of experiment revealed that, in respect of growth parameters viz., number of suckers plant^-1 and fresh and dry weight of plant, flower quality parameters viz., length of flower stalk, number of primary branches panicle^-1, length of panicle region, diameter of flower stalk and vase life of panicle were recorded significantly highest when planting was done on 15^th June and the suckers treated with 200 ppm GA₃ before planting. In respect of yield parameters viz., number of panicle hectare^-1 also the treatment of 15^th June planting and the suckers treatment with 200 ppm GA₃ before planting was significantly superior than other treatments.
