Abstract:
A field experiment entitled “Response of golden rod (
Solidago canadensis L.)
to planting time and GA
3” 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 GA
3 concentrations
viz., control i.e 0 ppm, 200 ppm and 250 ppm GA
3. 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 GA
3 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 GA
3 before planting was significantly superior than other treatments.
