Resumen
Se estableció un experimento para evaluar el efecto de dos distancias de siembra (0,80 y 1,00 m) y dos cantidades de plantas por sitio de siembra (1 y 2) sobre el crecimiento de Phoenix roebelenii. Se usó un diseño de Bloques Completos al Azar. El experimento se realizó en la Estación Experimental Fabio Baudrit M. de la Universidad de Costa Rica de Julio de 1996 a Marzo de 1998. El número de plantas/sitio de siembra afectó significativamente las variables bajo es- tudio, no así las distancias entre hileras de siembra. La altura de planta, número de hojas y longitud de hoja se afectó significativamente por la densidad de siembra usada. La densidad de siembra de 31.250 plantas/ha (0,80 m entre hileras y 2 plantas / sitio de siembra), produjo la mayor cantidad de hojas sanas (30,2 ) a los 21 meses de crecimiento, lo cual es importante en la producción y comercialización de hojas como follaje de acompañamiento. La producción de hojas comercializables (longitud mayor a 50 cm) se produjo a los 18 meses después de la siembra (26 meses de edad de las plamtas).
An experiment was conducted to study the effect of two planting distances (0.80 and 1.00 m) and two number of plants (1 y 2) per planting site on the growth of Phoenix roebelenii. A Complete Randomized Block experimental design was used. The trial was conducted at the Fabio Baudrit Experiment Station of the University of Costa Rica, from July 1996 through March 1998. The number of plants/planting site significantly affected the studied variables, but the distances between planting rows did not. The effect of planting density was significant on plant height, number and length of the leaves. The plant population of 31.250 plants/ha (0.80 m between rows and two plants/site) produced the largest number of healthy leaves (31.2) at 21 months of growth, which is very important on the production and marketing of leaves as foliage for arrangements. The production of marketable leaves (over 50 cm long) was obtained 16 months after planting (26 months of age of the plants).
