The present investigation was carried out to study the effect of different plant growth regulators on growth and yield attributes of greenhouse tomato using fourteen different treatments comprised of three levels each of three PGRs 4-CPA, 2,4-D and GA3 in a Randomized Block Design with three replications. Among different levels of PGRs, 30 ppm 4-CPA (Inflorescence dipping) exhibited maximum plant height of 203.47, 251.73 and 306.67 cm at 120, 180 days after planting and at final picking, respectively whereas, control (water spray) had maximum leaf area (843.33 cm2). Plants treated with 30 ppm 4-CPA (Inflorescence dipping) were found to be superior to all other treatments for majority of the reproductive parameters like fruit set (72.50%), fruits per cluster (5.80) and number of fruits per plant (58). The superiority of 4-CPA at the rate of 30 ppm (Inflorescences dipping) was also reflected by tomato plants in terms of significantly maximum fruit yield per plant (4.95 kg) as well as fruit yield per m2 (12.69 kg) except average fruit weight.
