Rendimento de grãos de soja com sementes inoculadas e coinoculadas: revisão bibliográfica

Abstract

Soy is the most commercially exploited crop in Brazil, and the country is the world's largest producer and exporter of the commodity. As production techniques evolve, there is a need to adopt new technologies aimed at increasing the efficiency, profitability and sustainability of the system. Thus, the use of microorganisms has been used in agriculture as a management alternative to increase productivity and reduce production costs. Inoculation of seeds with nitrogen-fixing bacteria of the genera Rhizobium and Bradyrhizobium are able to increase productivity and reduce the application of nitrogen fertilizers in the crop. In addition, coinoculation with growth-promoting bacteria of the genus Azospirillum contributes to the efficiency of fertilizer use, to the increase in productivity, intensification of plant root growth due to the production of phytohormones, increase in the number of nodules per plant and induction of resistance to environmental stresses. Thus, the aim of the study was to develop a literature review on seed inoculation and coinoculation on soybean grain yield. The inoculation and coinoculation of soybean seeds promote several benefits for the soybean crop, such as better photosynthetic capacity, greater root growth, greater productivity, enabling a more environmentally, economically and socially sustainable agriculture. There is a need for more comprehensive studies, aiming to study the behavior of nitrogen-fixing and growth-promoting bacteria in response to different production environments
