Abstract: In the Rabi season, we experimented on Tomato cv. Heemshikhar on 180 plants in a Poly-house at the School of Agricultural Sciences and Technology of RIMT University in Mandi Gobindgarh, Punjab, India, in 2022-2023. The experiment was layout in CRD (Completely Randomized Design) with three replications and ten treatments i.e. T1 (control), T2 (GA3 @50ppm), T3 (GA3 @75ppm), T4 (GA3 @100ppm), T5 (IAA @50ppm), T6 (IAA @75ppm), T7 (IAA @100ppm), T8 (NAA @50ppm), T9 (NAA @75ppm) and T10 (NAA @100ppm) under Protected conditions. The results revealed that at 20 days interval, maximum plant height (39.86, 64.35, and 117.33cm) and Number of branches/Plant (7.86, 13.00 and 19.66) we have recorded in treatment T10 (NAA@100ppm). However, the maximum number of flowers/Plant (26.50) and clusters/Plant (11.60), Days to first fruit set (51.66 days), days to first fruit picking (36.00 days), number of fruits/plant (25.00), fruits/cluster (4.66), Fruit weight (56.33g), Fruit length (12.66cm), Yield/plant (1.40kg), Yield/acre (16.90Tons), TSS (3.960Brix), Ascorbic acid (17.23%) and highest BC ratio (2.65) were recorded in T3 GA3 @75ppm whereas, lower value of most of the parameters were recorded in T1 control under poly-house conditions.
