Abstract: A field experiment was carried out during 2015-16, at the Horticulture Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut to find out the impact of foliar application of different levels of GA3 and NAA on reproductive and quality attributes of tomato cv. Pusa Rohini. The different treatment concentration tested were NAA (15, 20, 25 and 30 ppm), GA3 (20, 30, 40 and 50 ppm) and control (distilled water spray). All variables parameters related to yield and quality parameters were significantly influenced by different concentrations of the plant bio-regulators. Results revealed that among all the treatments, the foliar application of GA3 (50 ppm) registered significantly higher reproductive aspects viz., number of cluster per plant (7.07), number of fruit per cluster (6.73), number of fruit per plant (20.60), fruit set (65.09 %), fruit length (4.75 cm), fruit diameter (5.05 cm), fruit weight (61.95 g) and yield (531.74 q/ha). Themaximum TSS (4.93˚B) was recorded with the foliar application of GA3 (50 ppm), while minimum acidity per cent (0.463) in fruits was recorded under the foliar spray of NAA @ 25 ppm.
