Changes in plant height, tiller numbers, leaf area, and total dry mass accumulation are shown at different partial root-zone irrigation treatments. Values indicate the mean of eight plants; ± indicates standard error of the mean; letters indicate significant differences among means according to Student’s t-test. CD represents the critical difference at 95% (0.05) and 99% (0.01) confidence limit.
