Table 2. Effects of Pro-Ca spraying at the booting stage on rice yield and its constituent factors under salt stress.
The data in the table are the mean ± standard error (SE), and different lowercase letters in the same column indicate that the mean values of the replicates were significantly different among the treatments (p < 0.05).
