Effect of GA3 and urea on growth, and yield of gladiolus (Gladiolus grandiflorus L.) cv. Novalux

Abstract

The present investigation was carried out at Main Experimental Station, Department of Floriculture and Landscape, A.N.D.U.A. &T., Kumarganj, Ayodhya (U.P.), 224229 during the year 2018-19 to investigate the “Effect of GA3 and urea on growth, and yield of gladiolus (Gladiolus grandiflorus L.) cv. Novalux”. The experiment was laid out in Randomized Block Design (Factorial) with three replications and twelve treatment combinations comprising three levels of GA3 (0, 150 and 300 ppm) and four levels of urea (0%, 1.00%, 2.00% and 3.00 %) as foliar spraying at 30 and 60 days after sowing. The results revealed that 300 ppm GA3 and 3% urea resulted maximum plant height 76.93 (cm), maximum number of leaves 7.30 (cm) per plant, number of spike 2.20 per plant and 2.75 (lacks) per hectare, maximum number of corms 2.47 per plant and 3.08 lacks per hectare, maximum yield of cormels 48.46 (lacks) per hectare.
