Abstract
Six hardwood species planted on Sharkey clay soil that had been disked the first 5 years for weed control were significantly taller at age 5 when compared to species grown on mowed sites. By age 15, there were no differences in heights within species except for sweet pecan. Average heights by species at age 15 were: cottonwood (
Populus deltoides Barb. ex Marsh.), 60 feet; sycamore (
Platanus occidentalis L.), 38 feet; green ash (
Fraxinus pennsylvanica Marsh.), 36 feet; sweetgum (
Liquidambar styraciflua L.), 30 feet; Nuttall oak (
Quercus nuttallii Palmer), 27 feet; and sweet pecan (
Carya illinoensis (Wangenh.) K. Koch), 19 feet.
