Abstract:

The present investigation entitled “Effect of growth regulators for growth, yield and quality in brinjal (Solanum melongena L) cv. CO 2” was carried out during 2017 at Vanavarayar Institute of Agriculture, Manakkadavu, Pollachi. The studies were carried out with 8 different treatments involving the growth regulators (NAA@ 20 ppm, NAA@ 40 ppm, GA3@ 20 ppm, GA3@ 40 ppm,2,4-D@ 2ppm, 2,4-D@ 4ppm, Water spray and Control), sprayed at 20 and 40 DAT. The experiment was laid out in a randomized block design (RBD) with three replications and data on effect of different growth regulators on growth, yield and quality attributes was recorded and statistically analyzed. Among the treatments, the data recorded on plant height at 30 DAT revealed that there was significant difference among the treatments. Among the growth regulator, T4 – GA3 @ 40ppm concentration significantly increased the plant height (40.10 cm), Data on plant height at 60 DAT. Maximum plant height was recorded with T4 - GA3 @ 40ppm (54.30 cm), At 90 DAT, maximum plant height was recorded with T4 – GA3 @ 40ppm (76.50 cm). The data recorded on number of leaves at 30 DAT. T4 – GA3 @ 40ppm concentration significantly increased the number of leaves (22.50). Data on number of leaves at 60 DAT. Maximum numbers of leaves was recorded with T4 - GA3 @ 40ppm (49.20). At 90 DAT, maximum number of leaves was recorded with T4 – GA3 @ 40ppm (87.20), the highest number of primary branches was recorded in T4 – GA3 @ 40ppm (7.30), number of secondary branches was observed in T4 – GA3 @ 40ppm (18.70). Earliest days to first flowering was recorded in T4 – GA3 @ 40ppm (37.50days). The number of flower per plant T4 – GA3 @ 40ppm (24.60), the highest number of fruit set (%) was observed in T4 – GA3 @ 40ppm (57.80), number of fruits per plant, the highest number of fruits per plant was observed in T4 – GA3 @ 40ppm (17.80).
