Abstract
A miniature loblolly pine plantation was established in southeastern Arkansas in 2001. Two-month-old seedlings were planted in the spring of 2001 in a factorial arrangement of plots consisting of four within row spacings (10.2, 20.3, 30.5, and 50.8 cm) and four between row spacings (10.2, 20.3, 30.5, and 50.8 cm). Three replicates were installed. Half of the study was fertilized in February 2002 to incorporate fertilization into the experiment. To date vigor, root collar diameter, total height, and crown diameters in four directions have been measured five times. Fertilization has not had a significant effect on any of the attributes. Spacing did not have a significant effect on any attribute until the September 2002 measurement period, when the effect on root collar diameter and crown diameter was significant. By the January 2003 measurement, total height was also significantly affected by spacing.
