ABSTRACT
Chili (Capsicum annuum L.) is a popular food spice along with many medicinal benefits. The experiment to investigate the impact of plant growth regulator on the growth and yield characteristics of chili was conducted during Kharif season 2022 at the Horticultural research area, Faculty of agriculture, Gomal University. D.I. Khan. The experiment was laid out ten treatment with complete randomized block design and replicated three time. The treatment includes T1-control, T2-NAA@30ppm, T3-NAA@60ppm, T4- NAA@90ppm, T5- GA3 50ppm, T6- GA3 100ppm, T7- GA3 150ppm, T8- NAA@30ppm + GA3 50ppm, T9-NAA@60ppm + GA3 100ppm and T10-NAA@90ppm + GA3 150ppm. The outcome shows that the use of plant growth regulators significantly alters the growth and yield-related features in chili. Result revealed that the application of NAA@60ppm obtained significantly higher plant height (65.64), days for flowering (42.39), no of flowers (19), fruit length (6.97cm), fruit weight (2.60g), fruit diameter (2.99) and yield per plot (149.25), while the NAA@90ppm was outcome higher no of branches (22.50).
