The frequent shortages of loblolly pine seed for natural regeneration prompted investigation of ways to stimulate seed production of seed trees. Partial girdling failed because, as applied, it was too mild an injury. Fertilization was not effective with 40-year-old trees, but significantly increased the cone crop of 25-year-old trees. As explained in summary, the amount of fertilizer may have been inadequate for the 40-year-old trees.
