Conteúdo: 	Maize is highly responsive to the application of nitrogen to achieve high productivity. Inoculation with diazotrophic bacteria can improve plant growth with low N fertilization. The objective was to evaluate the inoculation of two species of diazotrophs on N metabolism in maize plants, in the presence of two concentrations of nitrogen in a hydroponic system. A factorial arrangement composed of two N levels (3.0 and 0.3 mM), with the presence of Hs?Herbaspirillum seropedicae, and Ab?Azospirillum brasilense or not. The parameters used were dry mass; N, P, and K accumulation; nitrate reductase activity; soluble fractions in roots and leaves. The inoculation altered the N metabolism and promoted greater development of maize plants, as well as a higher accumulation of P and K in the shoots. A more intensive process of N assimilation was evidenced when the plants were inoculated with H. seropedicae, leading to increased levels of NO3&#8722; and reduced N-amino, sugars, and NH4+ in leaves associated with high N level, opposite of A. brasilense.
