Analysis of Nine-Year-Old Sawtooth Oak Planted on Two Sites

Sawtooth oak (Quercus acutissima) seedlings of unknown provenance were planted on International Paper Company's Southlands Experiment Forest, Bainbridge, Georgia, on 2 sites, an old-field and a wild-land site. Treatments consisted of all oak, oak and loblolly pine (Pinus taeda), all pine, cultivation, and fertilization. After 9 years, pine was significantly larger (P < 0.05) than oak on both sites. On the old-field site neither cultivation nor fertilization showed a significant influence on the growth of either species. However, on the wild-land site cultivation significantly increased diameter, height, and volume of both oak and pine and survival of oak. Fertilization significantly increased diameter and volume of both oak and pine. Acorn production at age 9 appeared to be influenced only by spacing. Fertilization increased acorn crude fat and protein and decreased crude fiber.
