| Popis: | The present work investigated the effect of the use of diazotrophic bacteria Azospirillum brasilense, inoculated via seeds, in association or not with nitrogen doses, in the off-season, in the yield of oil in maize genotypes. The trials were carried out in two sowing times in a randomized complete block design (DBC) with 30 treatments and three replications. In each season, treatments were arranged in a 2x3x5 factorial scheme, represented by two seed inoculation processes (with and without inoculation), three corn genotypes (Orion and Al Bandeirante, open pollinated varieties, and Double Hybrid (kg ha-1), an analysis of individual variance and, afterwards, the results of the analysis of variance (kg ha-1) and five nitrogen doses (0, 50, 100, 150 and 200kg ha-1). The use of the Azospirillum brasilense bacterium, with or without nitrogen doses, promoted an increase in oil yield in the grains. The Orion variety was the one that stood out the most when inoculated with the bacterium Azospirillum, being the most efficient when cultivated Under nitrogen The adoption of this practice is not a substitute for the use of nitrogen fertilizers, but may be an alternative to reduce the costs of the producer. |
