In today’s situation, the use of growth regulators is playing an important role in increasing the yield and better quality crops. The findings showed that the use of plant growth regulators greatly enhanced the morphological characteristics, viz., number of branches plant–1, number of leaves plant–1, plant height (cm) and number of flowers plant-1 at maximum T3 (GA3 @ 75 ppm) (3.091, 3.906, 4.095 and 4.360) (12. 648, 17.115, 24.053 and 24.757), (44.503, 81.047, 87.778 and 89.974) and (4.587, 6.322, 6.755 and 6.486), respectively. While all the yield related parameters like- number of fruits plant-1, fruit length (cm), fruit breadth (cm) and fresh fruit weight (g) increased significantly due to use of plant growth regulators, the best among them was T3 (GA3 @ 75 ppm) (3.899, 5.374, 5.596 & 3.836), (12.150, 13.634, 13.566 & 13.107), (1.875, 2.073, 2.087 & 1.926) and (13.240, 13.237, 14.081 & 14.264), respectively. In foliar sprays, (GA3 @ 75 ppm) had the highest positive effect on plant growth regulators, followed by NAA, while it had the least effect in the control plots.
