The effects of several levels of competition control on the development on planted longleaf pine (Pinus palustris Mill.) bare-root and container seedlings was recorded at five locations in Georgia. Two intensities of pre-planting site preparation were each combined with two post-planting release treatments, Five years after planting, survival was better for container (76 percent) than bare-root (51 percent) stock. The height of container seedlings (6.0 ft) significantly exceeded that of bare-root seedlings (4.9 ft). Release significantly improved seedling growth and promoted a greater response from container (7.2 vs. 4.7 ft) than from bare-root seedlings (5.5 vs. 4.2 ft).
