Abstract

The effect of plantation design on resource utilization has not been adequately investigated in agroforestry plantations. An experiment was conducted near Booneville, AR, on a silt loam soil with a fragipan. Loblolly pine (Pinus taeda L.) trees were planted in 1994 in three designs: two rows (1.2 by 2.4 m) with a 7.3-m alley, four rows (1.2 by 2.4 m) with a 12.2-m alley, and a rectangular 1.2- by 2.4-m configuration. Each 0.4-ha design was replicated three times. Height and d.b.h. were measured for 6 consecutive years (2002 to 2007) in 0.047-ha plots. Tree height increased annually from 7.30 m (2002) to 13.27 m (2007). For any given year, d.b.h. was greatest in the two-row design, and the four-row design had greater d.b.h. than the rectangular design in 2004 to 2007. Exterior rows in the four-row design had greater d.b.h. than interior rows. Depending on design, plantations might be useful for alley cropping, silvopasture, or pine straw.
