TAILIEUCHUNG - Effect of foliar spray of plant growth regulators on growth and quality of sprouting broccoli (Brassica oleracea var. italica L.)
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.)
