BACTÉRIAS DO GÊNERO AZOSPIRILLUM: INOCULAÇÃO NO MILHO

Abstract

Brazil is the third largest corn producer in the world. Within the agricultural production of corn, nitrogen fertilizers constitute one of the highest costs of cultivation. The level of productivity in some places is low, one of the main reasons is the low availability of nutrients in the soil, mainly nitrogen. On the other hand, the crop can benefit from the biological nitrogen fixation (FBN) process and, in this way, reduce dependence on nitrogen fertilizers. FBN consists of a process of transforming N2 into the combined inorganic form NH3, which is carried out by microorganisms known as N2 fixers or diazotrophs. The aim of this study was to conduct a literature review on the importance of bacteria of the genus Azospirillum in association with grasses, specifically corn, through a literature review in journals and specialized periodicals on the Capes Periodicals portal, using the keywords: grasses, corn, Zea mays, N fixation, nitrogen, FBN, Azospirillum. The use of Azospirillum in the inoculation of corn seeds is an increasingly common practice.
