Abstract

The present study was conducted at the research farm and Horticulture lab of Sant Baba Bhag Singh University, Punjab during the year 2020 and 2021. The experiment was conducted in a randomized block design comprising of 9 treatments (T0 - Control, T1- GA3 @ 20 ppm, T2 - GA3 @ 30 ppm, T3 - GA3 @ 40 ppm, T4 - NAA @ 15 ppm, T5 - NAA @ 20 ppm, T6 - NAA @ 25 ppm, T7 - GA3 @ 30 ppm + NAA @ 20 ppm, T8 - GA3 @ 40 ppm + NAA @ 25 ppm) with three replications. Findings of the present study revealed that treatment T8 - GA3 @ 40 ppm + NAA @ 25 ppm resulted in highest number of leaves per plant (56), plant height (82.46 cm), number of flowers per plant (44.8), number of fruits (22.9), fruit diameter (5.83 cm), fruit weight (50.27 g), TSS (5.32 oBrix), fruit yield per plot (20.68 kg/plot) and fruit yield per hectare (344.69 q/ha). Hence, it is successfully established that the application of GA3 + NAA can be helpful in enhancing the yield and quality parameters of tomato crop thereby, improving the socio-economic status of the tomato growers.
