| dc.description | This document was made with the purpose of determining the importance of carrying out chemical weed control in the cultivation of corn planted by means of a direct sowing system, where it is essential to carry out an effective weed control due to the fact that by not practicing conventional tillage the Soil has coverage, which promotes that weeds develop more easily. For the development of this practical document, surveys were conducted consisting of seven closed questions, which were tabulated using the Microsoft Excel program and diagrammed in bar graphs. The interview was conducted with fifteen Rcto producers. Los Angeles, Canton Windows. Additional information was collected from publications of books, magazines, scientific articles, congresses, papers, newspapers, web pages; what was submitted to the technique of analysis, synthesis and paraphrase on the chemical control of weeds in the cultivation of corn, by means of a direct sowing system. According to what was developed, it was determined that most of the producers carry out the sowing of the corn crop through conventional tillage, not relying on the benefits obtained from zero tillage by taking advantage of the remains of plant materials that the soil has, which promotes erosion and prevents degradation of the same, accumulating organic matter, which provides nutrients and it is necessary that weed control is carried out with the doses and time of application of the products according to the development of the corn crop and weeds present , because if there is no adequate control, they compete with the crop for water, light and nutrients which significantly affects the yield. | es_ES |

| dc.description.abstract | El presente documento se realizó con la finalidad de determinar la importancia de efectuar el control químico de malezas en el cultivo de maíz sembrado mediante un sistema de siembra directa, donde es imprescindible efectuar un control de malezas eficaz debido a que al no practicar labranza convencional el suelo presenta cobertura, lo que promueve que las malezas se desarrollen con mayor facilidad. Para el desarrollo del presente documento de carácter práctico se efectuaron encuestas constituidas por siete preguntas cerradas, las que fueron tabuladas mediante el programa de Microsoft Excel y diagramada en gráficos de barras. La entrevista se realizó a quince productores del Rcto. Los Ángeles, Cantón Ventanas. Adicional se recopiló información de publicaciones de libros, revistas, artículos científicos, congresos, ponencias, periódicos, páginas web; lo que fue sometido a la técnica de análisis, síntesis y parafraseo sobre el control químico de malezas en el cultivo de maíz, mediante sistema de siembra directa. Según lo desarrollado se determinó que la mayoría de los productores realizan la siembra del cultivo de maíz mediante la labranza convencional, no confiando en los beneficios que se obtiene a efectuar la labranza cero al aprovechar los restos de materiales vegetales que dispone el suelo lo que promueve la erosión y evita la degradación del mismo, acumulando materia orgánica, la cual proporciona nutrientes y es necesario que el control de malezas se realice con las dosis y época de aplicación de los productos de acuerdo a al desarrollo del cultivo de maíz y a las malezas presentes, porque si no existe un control adecuado, éstas compiten con el cultivo por agua, luz y nutrientes lo que afecta significativamente el rendimiento. | es_ES |
