Abstract-Seedlings from an open-pollinated family of water oak (Quercus L) and cuttings from clones of eastern cottonwood (Populus Bartr. ex Marsh) and hybrid poplar (P. Torr. and Gray X P. Bartr. ex Marsh.) were tested on a Perry clay soil in east central Arkansas (St Francis County). The test site received a preplant application of 100 pounds of nitrogen per acre and weed control for two growing seasons. Unirrigated and irrigated test families were monitored for survival and growth through age two. Some Populus clones survived best when irrigated and other clones when unirrigated. All test material exhibited significantly more volume per planted tree when irrigated. After two growing seasons, irrigated exceeded unirrigated saplings with enhanced mean performance for height, diameter, and volume per planted tree of 3.1 feet, 0.6 inches and 19.9 respectively. Hybrid poplars exhibited more uniform early growth.
