| description | In three departments of the Corrientes province, the performance of 6 seeders was evaluated during corn sowing at three different speeds for each machine. A randomized complete block design was used with nested treatments arrangement. A seeder factor (6 types), a speed factor (3 levels) and three blocks determined a total of 54 experimental units. As for the speed factor, the first level corresponds to speed 2 (Sp 2) which the operator regularly uses. The second level and the third level correspond to a lower speed (Sp 1) and a higher speed (Sp 3) respectively which were used for this study. The equidistance between seeds and sowing depth were analysed as the response variable. Conclusions: 1) Four of the six seeders studied at three chosen speeds showed no differences regarding seed deposition. This was observed considering significant differences between sowing depth and seed spacing in a given line. 2) The two methodologies used to evaluate sowing efficiency, i.e. the coefficient of variation (CV) and the ISO 7256-1 standard, showed differences in evaluation. The second technique was more accurate since no differences between treatments were found with the CV. 3) According to these results, it is possible to conclude that the corn sowing quality in the Corrientes province is acceptable at the sowing speeds used by the contractors. |

En tres departamentos de la provincia de Corrientes, se evaluaron el desempeño de 6 sembradoras durante la siembra de maíz a tres distintas velocidades para cada máquina. El diseño experimental fue en bloques completos aleatorizados con arreglo anidados de tratamientos, siendo un factor sembradora (6 tipos) y otro factor velocidad (3 niveles) y tres bloques lo que determinó un total de 54 unidades experimentales. Se analizaron como variable respuesta, la equidistancia entre semillas y la profundidad de siembra. Conclusiones: 1) La mayoría de las sembradoras estudiadas a tres velocidades, no mostraron diferencias en la calidad de deposición de la semilla expresado como diferencias significativas entre la profundidad de siembra y el distanciamiento entre las mismas dentro de la línea. 2) Las dos metodologías utilizadas para evaluar la eficiencia de siembra (coeficiente de variación (CV) y norma ISO 7256-1) mostraron diferencias de evaluación, siendo más exigente esta segunda técnica ya que con el (CV) no se encon-traron diferencias entre tratamientos. 3) De acuerdo con los resultados encontrados es posible concluir que la calidad de siembra de maíz en la provincia de Corrientes es aceptable a las velocidades de siembra utilizadas por los contratistas.
