- Abstract
The use of nitrogen-fixing diazotrophs bacteria in grasses is a recent alternative that which allows reducing the use of agricultural inputs. In this aspect the Azospirillum brasilense has emerged as a viable alternative in reducing nitrogen application in field crops. The objective of this review was to gather information regarding the agronomic performance in the use of A. brasilense in wheat crops. Besides the obvious reduction in the need for nitrogen fertilization, is noteworthy that the inoculation allows obtaining agronomic results similar to those obtained with fertilizers, that is, presents efficiency in several important agronomic attributes. Generally it is observed increase in productivity as the crop is inoculated. The best results were obtained with the use of diazotrophic bacteria associated to nitrogen fertilizer, underscoring the fact that the bacterium does not completely replace the fertilization. The increase in productivity is attributed to the improved translocation of biomass to grains and in the increased photosynthetic activity, justified by the increase in green tissues and its root system, occasioned by the plant symbiosis with A. brasiliense.
