In a study of a Populus deltoides Lux plantation in 1983-86, mean height, diameter and volume increments were 17.2-24.6, 10.7-22.1 and 22.0-42.6% greater in irrigated trees than in those receiving rain only. Irrigation also increased stem and branch dry weight, leaf number and area, encouraging the accumulation of assimilates and their transport to branches.
