The experiment was conducted with the intention of investigating the impact of different concentrations and combination of the plant growth regulators on growth and yield contributing attributes of summer tomato. The experiment was laid out in Completely Randomized Resign (CRD) with four replications. Different plant growth regulators viz. T0= Control, T1 = 20 ppm NAA, T2 = 20 ppm GA3 and T3 = 20 ppm NAA + 20 ppm GA3 were used in the study. The growth and yield contributing characters were significantly influenced by the application of plant growth regulators. At harvest, the longest plant (86.90cm), number of cluster plant-1(9.95), bud cluster-1(8.01) flower cluster-1(5.94) and fruits plant-1(16.48) and fruit yield plant-1(309.04g) were found in BARI Hybrid Tomato-8. At harvest, the maximum plant height (88.30cm) was found in T2 and the number of number of cluster plant-1(10.12), bud cluster-1(8.26)flower cluster-1(5.99) and fruits plant-1(17.65) and fruit yield plant-1 (328.99 g) were found with the application of 20 ppm NAA+20 ppm GA3, whereas the minimum for these characters were recorded from control plants. In case of combined effect of variety and plant growth regulator, the maximum plant height (90.79 cm) was found in V4T2 which was statistically similar to V4T3, and the number of number of cluster plant-1(11.68), bud cluster-1(8.80) flower cluster-1(6.78) and fruits plant -1(23.95) and fruit yield plant-1(474.60 g) were found V4T3 whereas the minimum for all these characters were found in control plants. Therefore, it can be suggested that 20 ppm NAA along with 20ppm GA3 can be effective in enhancing growth and yield of summer tomato.
