Abstract
The experiment was conducted at Experimental farm of College of Horticulture, Dapoli, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri during Rabi season of the year 2019-20 to assess the effect of plant growth regulators on flowering and flower yield in gaillardia. The experiment was laid out in Randomized Block Design (RBD) with three replications with nine plant growth regulator treatments viz; T1- NAA @ 100 ppm, T2- NAA @ 200 ppm, T3- GA3 @ 100 ppm, T4- GA3 @ 200 ppm, T5- CCC @ 1500 ppm, T6- CCC @ 3000 ppm, T7- PBZ @ 250 ppm, T8- PBZ @ 500 ppm and T9- Control. The early initiation of flowering (62.00 DAT) was observed in GA3 @ 200 ppm treatment. The delayed initiation of flowering (90.33 DAT) and was in PBZ @ 500 ppm. The significantly minimum number of days required for 50% flowering (69.67 days) and longest flowering duration (130.73 days) were also taken in GA3 @ 200 ppm treatment. The lowest number of days required to flower opening from bud stage (4.33 days) and highest flower yield per plant (213.99 gm) were in GA3 @ 100 ppm (T3).
