RESPUESTA DEL MAÍZ PARA ENSILAJE A MÉTODOS DE SIEMBRA Y DENSIDADES DE POBLACIÓN

Abstract

El presente estudio tuvo como objetivo cuantificar la respuesta del maíz para ensilaje a métodos de siembra y densidades de población. Se establecieron dos experimentos en terrenos del Campo Experimental La Laguna (INIFAP), uno en primavera de 1993 y otro en verano de 1998. Se estudiaron cuatro métodos de siembra (surcos sencillos a 0.60 y 0.76 m; surcos dobles a 0.80 y 0.90 m) y densidades de población desde 5.3 hasta 15.5 plantas m-2. En cada parcela experimental se determinó la distribución de materia seca, rendimiento y calidad del forraje. No hubo diferencias estadísticas significativas por métodos de siembra en rendimiento de forraje seco y producción de grano. En primavera, el rendimiento de forraje seco se incrementó significativamente (16.7 %) con aumentos en la densidad de población de 8.2 a 11.2 plantas m-2. En verano, solo hubo incremento significativo en el rendimiento de forraje seco hasta una densidad de 8.6 plantas m-2. El rendimiento de forraje seco disminuyó significativamente (14.4-17.7 %) al reducir la densidad de población de 8.2-8.6 a 5.3-5.5 plantas m-2. La calidad del forraje no fue afectada por el método de siembra ni por la densidad de población. Probablemente, esta respuesta estuvo relacionada a la no reducción del índice de cosecha al aumentar la densidad de población.
