| description | One of the main difficulties in the organic, no-tillage system is weed management. The aim of this study was to evaluate the effect of the association between mechanical and cultural control methods (reduction of spacing and consortium with Canavalia ensiformis DC) on weed phytosociology and grain yield in maize with the organic, no-tillage system. The experiment design was a randomized complete block design with four replications, in a 2×3×2 factorial scheme, where the factors were, first factor: presence and absence of C. ensiformis; second factor: three weed management methods (without control, mowing and weeding), and third factor: two maize spacings (0.4 and 0.8 m). We evaluated the phytosociology of the weed community in maize stages V4 and V8, maize yield and dry matter of C. ensiformis. In the V4 stage, 21 weed species were identified, which were reduced to 16 species in V8. Cyperus rotundus presented a higher IR (Importance Value Index) in V4, and Panicum maximum had the highest IR in V8, independent of management. The C. ensiformis consortium with maize with 0.8 m spacing and weeding provided a higher grain yield. |

Una de las principales dificultades en el sistema orgánico de siembra directa es el manejo de malezas. El objetivo de este estudio fue evaluar el efecto de la asociación de métodos mecánicos y de control de cultivos (reducción de espaciamiento y cultivos intercalados con Canavalia ensiformis DC) en la fitosociología de malezas y el rendimiento de granos de maíz bajo un sistema de siembra directa orgánico. El diseño experimental fue de bloques al azar con cuatro repeticiones, en un esquema factorial 2×3×2, con el primer factor: presencia y ausencia de C. ensiformis; segundo factor: tres métodos de manejo de malezas (no controlado, corte y deshierbe), tercer factor: espacio entre dos hileras (0,4 y 0,8 m). Se evaluó la fitosociología de la comunidad de malezas en las etapas V4 y V8 del maíz, el rendimiento de grano del maíz y la materia seca del C. ensiformis. En la etapa V4 se identificaron 21 especies de malezas, reduciéndose a 16 especies en V8. Cyperus rotundus tiene la mayor IR (importancia relativa) en V4 y Panicum maximum la mayor IR en V8, independientemente del manejo. C. ensiformis en consorcio con maíz en el espacio de 0,8 m con desmalezado proporcionan un mayor rendimiento de grano.
