Abstract
Se informa sobre los resultados obtenidos en los viveros forestales, utilizando materiales de cubierta sobre las bolsas de polietileno dedicadas al cultivo de posturas de Hibiscus elatus Sw. El experimento repetido durante dos años, se desarrolló mediante un diseño de bloques al azar, con seis tratamientos y cuatro réplicas. Los materiales de cubierta utilizados fueron: arena de 0,02 a 0,2 mm, gravilla de 0,2 a 1 mm, cáscara de café, aserrín de madera de latifolias y hojas de latifolias picadas; como testigo se utilizó suelo solo, sin cubierta alguna. Se comprobó que el uso de materiales de cubierta sobre las bolsas, elimina el efecto de la compactación superficial del suelo, mejora el porcentaje de germinación y supervivencia y contribuye al mayor crecimiento en altura de las posturas de H. elatus. Los tratamientos que dieron mejores resultados fueron el aserrín fresco de madera de latifolias y en segundo lugar la cáscara de café.
