The experiment was conducted with different plant growth regulators viz., FANTAC (combination of vitamins and aminoacids) at four different concentrations (0.025 %, 0.05 % 0.075 % and 0.1 %), cytozyme at 2ml l-1, GA3 (20 ppm and 50 ppm), NAA (40 ppm) and Brassinolide (0.1 ppm). The treatments were replicated three times in a Randomized Block Design.

In chilli, foliar spray of FANTAC (0.025 %, 0.05 % 0.075 % and 0.1 %), cytozyme (2 ml l-1, GA3 (20 and 50 ppm), NAA (40 ppm), Brassinolide (0.1 ppm) were given at vegetative, flowering and fruit formation stage and compared with untreated control. Among the different growth regulator treatments, NAA 40 ppm significantly increased the growth parameters of chilli viz., plant height, number of primary branches and leaf area at all the different growth stages.
