Abstract

A field trial on the effect of GA3 and NAA was conducted on tomato cv. Kashi Vishesh during the rabi season of 2011-12. The different concentration of GA3 (20, 40, 60 and 80 ppm) and NAA (25, 50, 75 and 100 ppm) were sprayed on the crop to study the growth behavior and yield and yield 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 85.3 cm and 82.3 cm with the application of GA3 @ 80ppm and NAA @ 100ppm, respectively after 60 days of transplanting. Similarly, the yield and yield attributes were also affected significantly with increasing concentrations of GA3 and NAA. A maximum yield of 483.6q/ha and 472.2 q/ha was obtained with the use of GA3 @ 80ppm and NAA @100ppm, respectively.
