ARAUJO, Raul Matos; ARAUJO, Ademir Sérgio Ferreira de; NUNES, Luís Alfredo Pinheiro Leal  e  FIGUEIREDO, Marcia do Vale Barreto. Response of green corn to Azospirillum brasilense inoculation and N levels. Cienc. Rural [online]. 2014, vol.44, n.9, pp.1556-1560. ISSN 0103-8478.  http://dx.doi.org/10.1590/0103-8478cr20130355.

The aim of this study was to evaluate the effect of A. brasilense inoculation and nitrogen fertilization on green corn yield. The study was conducted out in Teresina, PI, in 2011 and 2012, and treatments were arranged in a randomized block design with five N rates (0, 50, 100, 150 and 200 kg N ha-1) with and without inoculation. In the inoculated treatment it was used a product with A. brasilense, strains Abv5 and Abv6. There was a significant increase in both number and mass of commercial corn cobs with A. brasilense inoculation as compared with treatment without inoculation. The association of inoculation with A. brasilence and nitrogen increase more than 30% the corn cobs production.
