Preliminary Investigation on Crop Growth, Physiology, and Yield of Rice under Partial Root-Zone Irrigation

Figure 5

Leaf pigment concentrations of PMK (R) 3 rice by split root experiment. Changes in leaf chlorophyll a, b, and a/b ratio at different irrigation treatments. Error bars indicate one standard error of the mean. Different letters denote significant differences among means derived using an ANOVA and Student’s t-test.
