Effect of Plant Growth Regulators and Micronutrients on Vegetative and Flowering Characters of Gladiolus (Gladiolus grandiflorus L.) cv. Novalux

To work out the effect of plant growth regulators and micronutrients on vegetative growth and flowering characters of gladiolus (Gladiolus grandiflorus L.) cv. Novalux, The experiment was conducted in Factorial Randomized Block Design with 12 treatments replicated thrice at the Main Experiment Station, Department of Floriculture &Landscape, Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.) during winter season in the year 2017-18 and 2018-19. The plant growth regulators and micronutrients application significantly influenced the growth and flowering attributes of gladiolus. The plant growth regulators significantly affects the days taken for complete sprouting of gladiolus. The earliest sprouting of corm, initiation of spike was found with Cycocel 500 ppm. The maximum plant height was noted in GA3 200 ppm with ZnSO4 0.5% + FeSO4 0.2%.The maximum number of leaves, Length of spike and number of spikes per hectare was obtained with the combinations of CCC 500 ppm with ZnSO4 0.5% + FeSO4 0.2%.
