The experiment consisted of sixteen treatment combination including four NAA (control, NAA @ 80, NAA @ 120 and NAA @ 180 ppm) and four GA3 levels (control, GA3 @ 25, GA3 @ 50 and GA3 @ 75 ppm) were undertaken randomized block design (RBD) with three replications at Horticulture Farm 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 plant height ( cm), number of leaves (), leaf area ( cm2 ), chlorophyll content in leaves ( mg/100g), total yield per plot ( kg), total yield per hectare ( q), ascorbic acid content ( mg/100 g), protein content ( %) and curd fiber content ( %) as compared to control and found statically at par to NAA @ 120 ppm. Similarly, GA3 @ 75 ppm significantly increased the plant height ( cm), number of leaves (), leaf area ( cm2 ), chlorophyll content in leaves ( mg/ 100g), total yield per plot ( kg), total yield per hectare ( q), ascorbic acid content ( mg/100 g), protein content () and curd fiber content () 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 leaf area ( cm2 ), yield per plot ( kg) and yield per hectare ( q/ha) which was significantly higher over rest of treatment combinations but statistically at par to N3G2, N2G2 and N2G3. | Effect of foliar spray of plant growth regulators on growth and quality of sprouting broccoli (Brassica oleracea var. italica L.)
