Rice Photosynthetic Productivity and PSII Photochemistry under Nonflooded Irrigation

Table 1

Soil characteristics of the field experiments conducted in Shihezi in 2011 and 2012. Values are the mean ± standard error (SE); the SE was calculated across five replicates in both years and averaged for the nonflooded irrigation and conventional flooding sites.
