The present investigation was carried out at the Central Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Kharif 2022-23 to identify the effects of different doses plant growth regulators and its role in growth, yield and quality of Chilli variety TMPH-409. The experiment was laid in Randomized block design with 19 treatments and 3 replications with different combination in plant growth regulators. Under this experiment, overall, 19 treatment was taken including control. Different plant growth regulators (PGRs) used comprised of NAA, GA3, 2-4 D, all four at different doses. According to the current research, the use of Plant growth regulators (PGRs) had a significantly positive impact on the growth and development of chilies. Among the various treatments that were evaluated, T7 yielded the most favourable results in terms of growth viz., plant height (88.06 cm at 90 DAT), number of primary branches (9.97 branches at harvest), leaf area (192.78 cm2), early days to 50% flowering (64.94 DAT) and yield viz., fruit weight (3.71 g), length of fruit (7.96 cm), fruit girth (3.00 cm), number of fruits per plant (251.62 fruits), and yield per plant (878.93 g/plant). T7 consisted of NAA at 40 ppm + GA3 at 100 ppm.
