Abstract
This study was navigated to examine the effectiveness of Bacillus wiedmanni SAB10 as a plant growth-promoting rhizobacteria (PGPR) that produced secondary metabolites for enhancement of growth, and recycling of essential nutrients. Bacterial strain was examined for non-symbiotic nitrogen fixation, indole- 3-acetic acid production, tri-calcium-phosphate solubilization, ammonia production, siderophore production and biofilm production. The seed application of bacterial strain promoted the overall dry biomass of Amaranthus viridis by 11.57% and overall length by 75.43% after 30 days of showing as compared to non-treated controls and its growth performance was similar to inorganic fertilizer applied plants. From this study it was concluded that Bacillus wiedmanni SAB10 is an effective plant probiotic that can colonize on the root and liberate active metabolites which exerted beneficial effects for the growth of Amaranthus viridis.
