The study on the influence of plant growth regulators in chilli cv. K 2 was carried out in pot culture with four growth regulators in three levels such as NAA (25, 50 and 75 ppm), triacontanol (5, 10 and 25 ppm), paclobutrazol (50, 100 and 250 ppm) and brassinosteroid (0.5, 1 and 2 ppm) with a control in 13 treatments in CRBD with five replications. The growth, physiological, yield and quality attributes were recorded as in the previous study along with plant nutrient uptake. Among the different treatments, brassinosteroid 1 ppm foliar spray on 45 and 90 DAT observed as the superior one for all the traits with the dry fruit yield of 2327.71 kg ha-1.
