Eighty-one accessions of oak species, hybrids, and cultivars from commercially available sources were established at TSU-NCRS in Fall 1993 and Spring 1994, using 10 single-plant replications in a randomized complete block. Drip irrigation was begun on a regular basis May 1994, and plants were fertilized regularly. Height and diameter was recorded Fall 1994 and 1995. Fastest growing oaks in order of cm height growth increment over the two growing seasons were nigra, phellos, texana nuttalli, cerris, macrocarpa, falcata pagodaefolia, macrocarpa `Maximus', acutissima, austrina, shumardii, muehlenbergi, falcata, robur fastigiata, lyrata, virginiana, palustris, acutissima `Gobbler', glandulifera, macrocarpa `Ashworth', gambelli ×macrocarpa, alba. Most evergeen oaks did not survive Winter 1995–96, and data will be reported on winterkill.
