Effect of type of tutors and population density on the yield of white yam: (Dioscorea rotundata Poir.)

The objective of the present investigation was to determine the effect of three types of tutors (individual tutor, simple espalier and double trellis) and two planting densities (14,285 and 20,000 plants/ha) on the performance of Dioscorea rotundata cv brasileiro. The experiment was carried out unde...

EFECTO DE TIPO DE TUTORES Y DENSIDAD DE SIEMBRA SOBRE EL RENDIMIENTO DE ÑAME ESPINO: (Dioscorea rotundata Poir.) LUNA CASTELLANOS, L. L. TAMARA MORELOS, R. E. GARCIA PEÑA, J. A. Dioscorea tubercle spatial arrangement individual support espalier Dioscorea tubérculo arreglo espacial soporte individual espaldera The objective of the present investigation was to determine the effect of three types of tutors (individual tutor, simple espalier and double trellis) and two planting densities (14,285 and 20,000 plants/ha) on the performance of Dioscorea rotundata cv brasileiro. The experiment was carried out under a randomized complete blocks design with arrangement in divided plots with four repetitions. The evaluated variables were: total yield of tubers (kg/ha), yield of commercial tubers, and additionally an economic analysis of the treatments was carried out. The results obtained showed highly signifi cant differences for the sowing density factor. When using the density of 20,000 plants / ha, the highest total yields (26,73 t. ha -1 ) were obtained, generating increases of 9.64% with respect to the lowest density (14,285 plants/ha) for this variable. The combined use of simple trellis and the density of 20,000 plants / ha generated  increases of 9.3% in yield of the tubers. El objetivo de la presente investigación fue determinar el efecto de tres tipos de tutores (tutor individual, espaldera simple y espaldera doble) y dos densidades de siembra (14,285 y 20,000 plantas/ha) sobre el rendimiento de Dioscorea rotundata cv brasilero. El experimento se realizó bajo un diseño de bloques completos al azar con arreglo en parcelas divididas con cuatro repeticiones. Las variables evaluadas fueron: rendimiento total de tubérculos (t. ha -1), rendimiento de tubérculos comerciales, y adicionalmente se realizó un análisis económico de los tratamientos. Los resultados obtenidos mostraron diferencias altamente significativas para el factor densidad de siembra. Al emplear la densidad de 20,000 plantas/ha se obtuvieron los mayores  rendimientos totales (26,73t. ha -1 ) generando incrementos en 9,64% respecto a la menor densidad (14,285 plantas/ha) para esta variable. La utilización combinada de espaldera simple y la densidad de 20,000 plantas/ha generó aumentos de 9,3% en rendimiento de los tubérculos.
