Abstract

Rice is a food widely consumed in some countries of the world, including Brazil. In order to increase productivity and improve their knowledge in the fields of upland rice sprinkler, mostly present in the cerrado, studies are being done using cover crops and no-tillage system in order to provide greater benefits for the soil and culture and the use of nitrogen-fixing bacteria aimed at saving nitrogen fertilizers. Thus, the work aims to study the effect of vegetation cover and Azospirillum brasilense inoculation in rice upland BRS Emerald grown in succession on tillage. The experimental design is randomized blocks arranged in a factorial 10x2. The treatments were a combination of the effect of corn stubble, Crotalaria spectabilis, Guandu and Estilosantes and the presence and absence of seed inoculation with Azospirillum brasilense, with four replications. The study is being conducted at the Experimental Farm Research & Education belonging to the Faculty of Engineering - UNESP - Single Island, located in Selvíria - MS. During the development of the project the following evaluations will be performed: dry mass of vegetation, seedling emergence, flowering, leaves nitrogen content, maturity, plant height, degree of lodging, number of panicles per square meter, total number of grains per panicle, number of granados and voids per panicle grain weight of 100 grains and grain yield.
