This study was initiated to determine growth response resulting from the application of prescribed fire and herbicide, with and without fertilizatio.n. In. southeast Texas, herbicide, prescribed fire and fertilizer treatments were applied in m1d:rotat1onal loblolly pine plantations 1.5 years after thinning. Five replications were established at. each of two study sites located on similar soils, aspects and slopes. Half of each replication. was randomly selected and fertilized. Eight treatment plots were established 1n e~ch replication with one of each of the four treatments of control, herbicide, fire, and herb1c1de/flre randomly applied to fertilized plots and one of each of the four treatments randomly applied to non-fertilized plots. Pre-treatment measurements were taken in a 0.04 ha measurement plot nested within each treatment plot. A late season herbicide treatment of. lmazapyr and Arsenal was applied in October 1999. Burning was conducted in early spring of 2000 followed by fertilizer applications of diammonium phosphate and urea. ~osHreatment measurements were taken in December 2000. Growth response and s1gnif1cant treatment differences are presented in this paper.
