Abstract

To evaluate the influence of two legumes: pork bean (Canavalia ensiformes) and Guandu beans (Cajanus cajan (L.) Millsp.) planted in alternating rows with two spacings on the community of weeds in fields without burning, a count the species was held to 105 days from planting in nine transects of 24m² (6m x 4m) each. T1 treatments (1m between lines) were compared; T2 (0.5 m between rows) and T control (without legumes). With three replications. The dried specimens were taken for identification in the Herbarium (MG) of the Emilio Goeldi Museum. The fitossocilogico survey at Mata program NATIVE and the similarity between the transects in the Past 3:04 program indicated that the presence of legumes and planting spacing between them influenced the diversity and structure of weed communities.
