A field trial on the effect of different plant growth regulators viz., GA3, NAA and 2, 4-D was conducted on tomato cv. Azad T-6 during the rabi season of 2014-15. The different concentration of GA3 (10, 20 and 30 ppm), NAA (20, 25 and 30 ppm) and 2, 4-D (5, 10 and 15 ppm) were sprayed on the crop to study the vegetative growth behaviour attributes of tomato. It was found that there was a linear increase in growth parameters like plant height and number of branches per plant with increasing level of GA3 and NAA. The maximum plant height was recorded as 99.03 cm and 85.47 cm with the application of GA3 @ 30 ppm and NAA @ 30 ppm, respectively at the time of harvesting Similarly, the other growth attributes were also affected significantly with increasing concentrations of GA3, NAA and 2,4-D.
