At 15 DAT, the mean leaf number was found to be 131.52. The maximum leaf number was observed from GA3 at 50 ppm (147.33) followed by GA3 at 100 pm (136) and NAA at 100 ppm (41.33). Kumar et al. (2023) also reported the maximum and minimum leaf number from GA3 at 50 ppm and from control treatment. The minimum leaf number was observed from control treatment (120.33) and NAA at 50 ppm (120.33). At 30 DAT, the mean leaf number was found to be 137.85. The maximum leaf number was recorded from GA3 at 50 ppm (167.67) and NAA at 100 ppm (162) whereas the minimum leaf number was observed from control treatment (105). However, the maximum and minimum leaf number was recorded from GA3 at 50 ppm and control treatment at both 15 DAT and 30 DAT. 3.1.3 Number of branches It is clear from the data that the application of GA3 and NAA significantly affected on number of branches of cabbage at 30 DAT whereas the treatment was found non-significant at 15 DAT (Table 2). It might be due to various environmental factors like light, temperature and nutrient availability which can modulate the plant’s response to hormones. The mean branch number at 15 DAT was found to be 31.14. The maximum branch number was observed from GA3 at 100 ppm (49.83) which was significantly similar with NAA at 100 ppm (43.17). The minimum number of branches was observed from control treatment (27.33) along with GA3 at 50 ppm (29.17) and GA3 at 75 ppm (29.17) which was statistically at par with NAA at 50 ppm (32.83) and NAA at 75 ppm. 3.1.4 Canopy cover The analyzed data revealed that the canopy cover was significantly influenced by the application of different concentrations of GA3 and NAA (Table 2). The canopy cover was also found non-significant at 15 DAT. The mean canopy cover recorded was 31.14 cm.
