Abstract

Diameters at age 10 of cottonwood (Populus deltoides Bartr. ex Marsh.) select clone Stoneville 66 planted at 40- by 40-foot spacing varied from 13.4 to 16.4 inches depending on height of pruning. Pruning treatments, applied from the 2nd through 8th years, were (1) unpruned, (2) pruned to a third of height yearly, (3) pruned to half of height yearly, and (4) pruned to 17 feet when d.b.h. >8.5 inches. Total tree heights did not differ among treatments and averaged 94 feet.
