Response of golden rod (Solidago canadensis L.) to planting time and GA3

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., 15th June, 15th July, 15th August and 15th 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 15th 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 15th June planting and the suckers treatment with 200 ppm GA3 before planting was significantly superior than other treatments.
