Biological nitrogen fixation (BNF) can be viable through the use of bacteria of the genus Azospirillum, a micro-organism potential plant growth promoter. In this sense, the present work was carried out with the objective to study the effect of Azospirillum brasilensediazotrófica bacteria use, inoculated via seeds, in association or not with doses of nitrogen, productivity of corn for industrial purposes. The essays were conduced on two sowing times(10/07 and 8/1/2015), in the inter-crop season, in Palmas-TO, The experimental design in both sowing dates was randomized blocks with 30 treatments and three replications. The treatments were arranged in a factorial scheme 2x3x5, represented by two seed inoculation processes (with and without seed inoculation ) Three genotypes (Orion and Al Bandeirante, open-pollinated varieties, and the double hybrid (AG-1051) and five N levels of nitrogen (0,50, 100, 150 and 200 kg ha-1) held in coverage. The characteristic studyed was the productivity of grain. Inoculation with Azospirillum brasilense was beneficial under adverse conditions. AG 1051 was potentially superior when inoculated under stress conditions.
