In this article, Fig. 1, Fig. 2 and the figure legends were incorrect. The figures should have appeared as shown below.

Fig. 1
figure 1

a Membrane permeability (MP), b chlorophyll content (Chl), c leaf relative water content (LRWC), d stomatal conductance (SC), e and leaf temperature (LT) at different irrigation levels and applications. Within each column, means followed by the different letters are significantly by the Duncan test at P<0.05. 100%, 70%, and 40% of the field capacity. Control nutrient solution at 0 (without HA or Si), HA humic acid, Si sodium silicate, HA+Si humic acid and sodium silicate combination

Fig. 2
figure 2

a L-proline and b malondialdehyde (MDA) at different irrigation levels and applications. Within each column, means followed by the different letters are significantly by the Duncan test at P< 0.05. 100%, 70%, and 40% of the field capacity. Control nutrient solution at 0 (without HA or Si), HA humic acid, Si sodium silicate, HA+Si humic acid and sodium silicate combination
