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

Figure 4

Leaf water use efficiency, photosystem efficiency, and canopy temperature measurements of rice under the split root experiment. Changes in leaf intrinsic (P_N/) (a), instantaneous (P_N/T_r), (b) Water Use Efficiency, photosystem efficiency (PS II efficiency) (c), and canopy temperature (d) at different partial root-zone 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.
