    Description

    In 1994, under a cooperative effort between Temple-Inland Forest Products Corporation and Stephen F. Austin State University, 84 permanent research plots were established in two loblolly pine (Pinus taeda) plantations in eastern Texas. The study was designed to evaluate the effects of heavy thinning, pruning, fertilization, and competition control on future growth and yield. Three different levels of thinning treatments on randomly selected plots reduced basal areas to 36, 60, and 84 square feet (approximately 100, 200, and 300 stems, respectively) per acre. All residual trees were pruned to a height of 25 feet. Treatments also included two levels of fertilization (fertilized and not fertilized) and two levels of competition control (herbicide and no herbicide). The objective of this paper is to summarize the growth responses on these research plots 8 years after application of cultural treatments.
