Abstract:
An experiment entitled “Effect of spacing and GA₃ on growth, flowering and yield of golden rod” was carried out during Kharif season of the year 2019-2020 at Satpuda Botanical Garden, Horticulture Section, College of Agriculture, Nagpur, Dr. PDKV, Akola (M.S.). The treatments comprised of four spacing viz., 30 x 10 cm, 30 x 20 cm, 30 x 30 cm and 30 x 40 cm and three levels of GA₃ viz. 0 ppm (control), 100 ppm and 150 ppm. Before planting suckers of golden rod were dipped in GA₃ solution of different concentrations as per the treatment for 6 hours. The experiment was laid out in Factorial Randomized Block Design with three replications. The results revealed that, in respect of growth parameters, plant height with panicle, number of leaves plant^-1 and plant spread were recorded significantly maximum with the spacing of 30 x 40 cm and suckers treatment with 150 ppm GA₃. In respect of flowering parameters, initiation of panicle and opening of first flower were registered significantly earliest when golden rod suckers planted at the spacing of 30 x 40 cm and treated with 150 ppm GA₃. The yield parameters like number of panicles plant^-1 and ha^-1 were also found significantly maximum with the spacing of 30 x 40 cm and the sucker’s treatment with 150 ppm GA₃.
