Abstract: The experiment consisted of sixteen treatment combination including four NAA (control, NAA @ 80 ppm, NAA @ 120 ppm and NAA @ 180 ppm) and four GA3 levels (control, GA3 @ 25 ppm, GA3 @ 50 ppm and GA3 @ 75 ppm) were undertaken randomized block design (RBD) with three replications at Horticulture Farm S.K.N College of Agriculture, Jobner (Jaipur) during rabi 2018-19. The result of study clearly indicated that application of NAA @ 180 ppm to the sprouting broccoli significantly increased the weight of primary head (250.50 g), secondary head (150.90 g), diameter of head (15.30 cm), total yield per plot (6.42 kg) and total yield per hectare (198.25 q) as compared to control and found statically at par to NAA @ 120 ppm. Similarly, GA3 significantly increased the weight of primary head (275.75 g), secondary head (151.51 g), diameter of head (14.10 cm), total yield per plot (6.44 kg) and total yield per hectare (198.64 q) as compared to control and statistically at par to GA3 @ 50 ppm. The interaction effect of NAA @ 180 ppm and GA3 @ 75 ppm (N3G3) was recorded maximum head diameter (17.74 cm), yield per plot (8.21 kg) and yield per hectare (253.25 q/ha) which was significantly higher over rest of treatment combinations but statistically at par to the treatment combination N3G2, N2G2 and N2G3.
