Abstract:
A field experiment was conducted during rabi season of 2020-21 at the Organic Research Farm, Karaguanji, Bundelkhand University, Jhansi (U.P.) To study the influence of plant growth regulators on growth and corm yield of Gladiolus. The results revealed that the plant growth regulators (GA₃ and CCC) significantly influenced the growth and corm production of Gladiolus. The maximum plant height, minimum days for spike initiation, long length of spike, number of spikes per plant and per hectare, spike weight and rachis length were found significantly superior with the foliar application of GA₃ (200 ppm). Whereas foliar application of CCC (200 ppm) gave superior results regarding number of corms per plant and per hectare, weight of corms and cormels per plant, diameter of corm, number of cormerls per plant and per hectare. Hence, on the basis of results obtained from the present investigation, it can be concluded that the foliar application of GA₃ (200 ppm) was found the most effective with respect to vegetative growth and spike characters, while CCC (200 ppm) was found the most effective with respect to different characters of corm and cormels as well as net return/ha from Gladiolus. Hence CCC (200 ppm) can be recommended to the farmers for commercial cultivation and with maximum economical gain from Gladiolus (Rose supreme).
