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.
