Figure 2

(a) The leaf relative turgidity (RT) and (b) the chlorophyll content (Chl) of maize plants affected by the application of optimized doses of sulfate fertilizers (K2SO4, FeSO4, CuSO4 and Na2SO4) under normal (100% WHC) and drought stress (30% WHC) conditions. The mean values with different letters indicate significant difference (P ≤ 0.05), according to post hoc Tukey’s test.
