Abstract:
Biosurfactants are the surfactants produced from microorganisms which contain both hydrophilic and hydrophobic moeity. Green compounds such as biosurfactants were evaluated for their plant growth promotion in a pot culture under greenhouse conditions. The efficient biosurfactant and plant growth promoting isolates BPB-17 and BPB-48 were evaluated in a pot culture under greenhouse condition and compared with the one reference strain (Bacillus sp.) and PGP bacteria (Azotobacter chroococcum) at different time interval (Upto 90 days after transplanting). The efficient isolates were evaluated in order to explore the effect of biosurfactants produced from these isolates in improving the plant growth of chilli (Arka Meghana). Among all the treatments, soil inoculated with BPB-17 showed the improvement in plant growth parameters like plant height, leaf area index, number of leaves, number of branches, shoot and root biomass and yield parameters such as number of leaves, number of fruits per plant and fruit yield which is followed by treatment inoculated with BPB-48.
