The hypothesis of this research was to verify the feasibility of using rhizobacteria in maize production, aiming to reduce the effect of water stress and the use of nitrogen fertilizers. Therefore, the objective of this study was to evaluate the morphophysiological responses and yield of maize plants inoculated with A. brasilense cultivated under two water conditions and with two nitrogen fertilization situations. The experiment was carried out in a field under irrigated conditions (IR) and water stress (WS) using a randomized block design with split plots. The treatments consisted of two concentrations of nitrogen (N) applied to the soil (20 and 120 kg ha?1) and three inoculation levels of A. brasilense (Az1, Az2, and control), with four replications. Stomatal conductance, chlorophyll content, leaf area, yield, harvest index, and soil enzymes (arginase and urease) were evaluated. Inoculation with Az1 and Az2 resulted in an increase in chlorophyll content, regardless of N content in the soil and water conditions. With Az2, there was a 10% increase in grain yield regardless of water condition and soil N content. Inoculation with Az2 level of A. brasilense and 120 kg ha?1 of N under IR was the best treatment that resulted in the highest maize yield, around 10%. Under water deficit conditions, plant inoculation with A. brasilense may reduce the effects of environmental stress by approximately 11%; however, the inoculation was not enough to equalize the maize yields to those observed in irrigated areas with the inoculant Az1 and 120 kg ha?1 of N, which promoted the best results. The inoculation of plants with A. brasilense is a cheap and easy-to-use technology that should be considered for the sustainability of maize production.
