ABSTRACT
A field experiment consisting of growth regulators NAA (40, 50 and 60 ppm), GA3 (25, 50 and 100 ppm) and Paclobutrazol (100, 150 and 200 ppm) and distilled water spray as control to study the effects of plant growth regulators on yield and andrographolide content of kalmegh (Andrographis paniculata Nees). Application of paclobutrazol at 100 ppm significantly increased the fresh herb and dry herb weight, stem and their total. The foliar application of NAA at 50 ppm was very effective and recorded maximum cumulative dry herb yield, drying percentage and total andrographolide yield (3662 kg/ ha, 54.5 % and 58.89 kg/ ha respectively).
Keywords: Andrographis paniculata, Andrographolide, Plant Growth Regulators, Whole Plant Biomass, Andrographolide yield.
