Abstract

Rice (Oryza sativa L.) is among the most produced and consumed cereals in the world, being a crucial component for food and nutritional security, in addition to generating jobs and income for producing countries. The interaction of methods such as crop diversification, green manuring and the use of good cultural practices, including the use of beneficial microorganisms, can increase crop productivity, contribute environmentally and economically to the adoption of more sustainable agricultural production systems. The experiment will be conducted in an experimental area of the Teaching and Research Farm belonging to the Faculty of Engineering of Ilha Solteira - UNESP, located in the municipality of Selvíria - MS, in soil originally with cerrado vegetation. Sowing will be carried out in November 2023, with an experimental design in randomized blocks arranged in a 5x4 factorial scheme (combination of coverage factor x inoculation factor). The objective is to evaluate the effects of vegetation coverings, intercropping of cultures and management of the inoculation of beneficial microorganisms (Rhizobium tropici and Azospirillum brasilense) in an already consolidated no-tillage system on the development and production of the upland rice crop irrigated by sprinkling in the region of the Cerrado, with the hypothesis of observing whether previous cultivations in the area and beneficial microorganisms can interfere with the response of the implanted culture.
