Abstract


The biological nitrogen fixation provided by diazotrophic bacteria may represent an alternative to maize production in more sustainable agricultural systems or low use of technology. In order to evaluate the growth, content and accumulation of nitrogen in corn genotypes, depending on seed inoculation with Herbaspirillum seropedicae experiment was conducted in greenhouse evaluating 35 corn genotypes hybrid single, double, triple and varieties. For seed inoculation was used peat inoculant containing the bacterial strain of H. seropedicae (ZAE 94). Among the commercial corn genotypes studied, only nine hybrids show increase of growth or accumulation of N with the seed inoculation with Herbaspirillum seropedicae (ZAE 94). There is a distinction in response between maize cultivars in terms of biomass production and increase of N content in the shoots.
