Efeitos da co-inoculação de azospirillum brasilense e pseudomonas fluorescens associados adubação química e orgânica na cultura do milho

Abstract

The indiscriminate use of synthetic fertilizers can cause environmental effects and even extinguish the natural reserves of certain elements, such as fertilizers with chemical residues associated with bacteria, and an alternative that aims to improve plant nutrition more sustainably. This work is resumed in the combination of fluorescent Pseudomonas and Azospirillum brasilense co-inoculation with two sources of fertilization: one synthetic and the other organic with poultry litter. A randomized design in a greenhouse and a randomized block design in an experimental field, with evaluation fins Azospirillum brasilense and Pseudomonas fluorescens, in a production system with chemical fertilizers and organic fertilizers. Where it has been found that these bacteria when used together promote an increase in root volume, may increase maize yield.
