ABSTRACT
The field experiment was conducted to study the growth, yield and quality of Kalmegh (Andrographis paniculata Nees.) as influenced by seedling treatment with plant growth promoting rhizobacteria at College of Horticulture, Bengaluru, during 2012-2013. The experiment was carried out by imparting eight different seedling treatments viz., T1 : Azospirillum lipoferum, T2 : Bacillus megaterium, T3 : Pseudomonas fluorescence, T4 : Azospirillum lipoferum + Bacillus megaterium , T5 : Azospirillum lipoferum + Pseudomonas fluorescence, T6 : Bacillus megaterium + Pseudomonas fluorescence, T7 : Azospirillum lipoferum + Bacillus megaterium + Pseudomonas fluorescence, T8 : Control. The experimental result showed that seedlings treated with combination of Azospirillum lipoferum + Bacillus megaterium + Pseudomonas fluorescence recorded highest plant height (48.13 cm), plant spread (1603.03 cm2), minimum number of days taken for 50 per cent flowering (77.90 days), maximum fresh weight of leaves (47.67 g), stem (136.00 g) and root (20.00 g), dry weight of leaves (27.67 g), stem (91.67 g) and root (10.17 g), total fresh biomass (202.67 g/plant) and total dry biomass (129.51 g/plant), highest andrographolide content in leaves (2.23%) and stem (1.95%) at harvest and the maximum benefit cost ratio (1:2.39).
Key words :
