Aims The aim of this study was to evaluate its feasibility of a non-symbiotic nitrogen-fixing strain, Ac63 ( Azotobacter chroococcum ), to promote biomass of common vegetable crops and its colonization mechanisms in their roots. Methods Root exudates of common vegetables, including Amaranthus tricol...
