Abstract

On a well-drained site in northwest Louisiana, effects of seedling type (container, bareroot) and herbicide site preparation (hexazinone, hexazinone + sulfometuron, imazapyr + metsulfuron) on loblolly pine growth and survival have been tested for 11 years. All possible combinations of these treatments were applied to loblolly pine planted at 302 trees acre-1, and these treatments were compared to a special control treatment planted at a spacing of 605 trees acre-1 to test tree density effects on yields. Results indicate container seedlings may be preferable to bareroot seedlings as planting stock for a welldrained site, and herbicide site preparation mixtures that provide broad-spectrum control are most effective in producing longterm growth benefits. Further research will be necessary to ascertain the effects of planting density on yields and product classes, but results thus far suggest container seedlings planted at a wide spacing are a viable management option for this type of site.
