The present investigation was carried out at the Experimental Farm of the School of Agriculture of Lovely Professional University, Phagwada, Jalandhar, during 2016-2017 to find out the effects of plant growth regulators on growth and yield of tomato cultivar ‘Shivaji’. The experiment was laid out in Completely Randomized Design having ten treatments and three replications. Treatments consist of different levels of GA3 (25, 50 and 75 ppm), NAA (25, 50 and 75 ppm) and Kinetin (25, 50 and 75 ppm) along with control. These different concentrations of GA3, NAA and Ki were sprayed on the crop at 7, 14 and 21 days after transplanting to study the growth behavior and yield attributes of tomato. All growth, phonological as well as yield parameter was found to be significantly superior at different concentration of GA3, NAA and Ki as compare to control treatment. Maximum plant height (104.33 cm), number of leaves per plant (64.73) and number of branches per plant (11.20) at 90 days after transplanting, minimum days to 50 % flowering (44.40 days), maximum numbers of flower per plant (61.00), fruit length (6.10 cm), fruit diameter (5.93 cm), number of fruit per plant (30.80), fruit yield per plant (3.66 kg) and fruit yield per ha (1355.56 tonnes) was reported in treatment where plant has been sprayed with 50 ppm GA3.
