Uso do Azospirillum brasilense na cultura do milho

Abstract

The maize crop has a high cost with fertilization and the climatic adversities associated with water and thermal stresses have become increasingly frequent. Thus, it is essential to seek alternatives to promote environmental conditions that are more favorable to the plant's physiology and reduce costs. Biotechnological technologies, such as the use of Azospirillum brasilense, have been investigated in several annual crops, including maize. Although the initial results are promising, adoption in the field is still very incipient. In view of these gaps, this review article discusses the main aspects associated (ecological; physiological; inoculation methods; co-inoculation; possibility in organic systems; reasons for low adherence) to the use of this diazotrophic bacterium in maize crops.
