Control de malas hierbas: Densidades de siembra y rotaciones de cultivo

Abstract

La rotación de cultivos ha sido uno de los métodos tradicionales para el control de las malas hierbas, que se ha visto desplazada por factores económicos, monocultivo de cereal y uso de herbicidas. Por otra parte no siempre son evidentes las ventajas de una aplicación de herbicidas, particularmente en densidades bajas de infestación de malas hierbas (Pardo et al., 2002 y Chao et al., 2002). Aumentar las densidades de siembra en los cereales también han sido empleadas como forma de aumentar la competencia del cultivo frente a las hierbas acompañantes y disminuir de esa forma el daño que estas causan en los rendimientos de los cereales. Actualmente sigue empleándose la expresión de “sembrar con mucho pan” para justificar está practica tradicional. Determinar la densidad optima de siembra ha sido objeto de varios trabajos con desigual resultado (Moreno et al., 2002 y Lacasta et al., 2004), las causas son las diferentes condiciones experimentales. En este trabajo se pretende evaluar la interacción de estas dos formas tradicionales de control de malas hierbas (rotación de cultivos y densidades de siembra) y su efecto sobre la productividad del cereal en las condiciones de semiáridez de los secanos y en un experimento de larga duración (14 años).
