Abstract

Chili peppers are fruit-bearing plants from the Capsicum genus, and they are known for their spicy and pungent flavors. Chili peppers thrive in warm climates and can be grown in various types of soil. They are typically cultivated as annual plants, although some varieties can be perennial in suitable conditions Therefore, 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 2021-22 with a view to identify the effects of different doses plant growth regulators and its role in growth, yield and quality of Chilli variety TMPH-443. The experiment was laid in Randomized block design with 13 treatments and 3 replications with different combination in plant growth regulators. Under this experiment, overall, 13 treatment was taken including control. Different plant growth regulators (PGRs) used comprised of NAA, GA3, 2-4 D and Triacontanol 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 Chillies. Among the various treatments that were evaluated, T5 (NAA @ 40 ppm spray) yielded the most favourable results in terms of growth viz., plant height, leaf area, early flowering and maturation and yield viz., fruit weight, length of fruit, fruit girth, number of fruits per plant, and yield per plant.

Keywords: NAA, GA3, 2-4 D, PGRs, chilli
