Abstract:

Currently the use of Azospirillum  have been indicated to crop management practices, due to N₂ fixation from the atmosphere by this bacterium, which improves the synthesis of auxin and gibberellins, stimulates root growth, and thus, the absorption of water and nutrients, resulting in increases in productivity of several crops such as Oryza sativa, Brachiaria spp., Saccharum officinarum, Zea mays and Triticum aestivum, as well as reducing the amount of nitrogen fertilizer applied, or acts indirectly by protecting the plant pathogens present in soil, through the production of siderophores, chitinases, glucanases and antibiosis. For the management of this technology, there are various forms of reported use in liquid form, peat, applying post-emergence spraying seed furrows and use of pelleted seed, and the recommendation is the application directly in the seed coat in the form of liquid or peat. Thus, this review aimed to relate characteristics linked to biological nitrogen fixation in grasses, as well as modifications in physiological, morphological and biochemical levels promoted by inoculation and potential of Azospirillum utilization on several crops.
