Description: During the first 10 years, unthinned cottonwood planted at four spacings grew from 2.8 to 3.4 cords per acre per year in trees 5.0 inches in d.b.h. and larger. Two basal area controlled thinning treatments did not increase yields. Initial spacings were 4 by 9, 8 by 9, 12 by 12, and 16 by 18 feet on Commerce-Convent soils. Only trees at the widest spacing averaged an inch of diameter growth annually for the 10 years.
Keywords: Populus deltoides, thinning, growth and yield
