Production time and container size for Simarouba amara Aubl. seedlings

Abstract

This study aims to determine the effect of nursery production time and container size on the quality standards of production of Simarouba amara seedlings based on nursery and field performance. The work was conducted in two phases: evaluation of nursery growth and field performance. A completely randomized design was used in both phases. Three container sizes (55, 180 and 280cm³) and four nursery production times (105, 125, 135 and 145 days) were tested. Height, collar diameter and survival were evaluated. S. amara seedlings can be produced in a 180 cm³ container with a maximum nursery production time of 125 days. The quality standard for seedlings corresponds to collar diameter ≥ 4.2 and height ≥ 9.1 cm.
