Impact of individual and combinatorial application of SNP and NaHS on nutritional status, i.e., magnesium content in the roots (A), magnesium content in the shoots (B), phosphorus content in the roots (C), phosphorus content in the shoots (D), iron content in the roots (E), iron content in the shoots (F), calcium content in the roots (G), and calcium content in the shoots (H) of spinach (S. oleracea) plants grown under different levels of Cr [0 (no Cr), 150, and 300 μM] in sandy loam soil. Values in the figures indicate just one harvest. Mean ± SD (n = 4). Two-way ANOVA was performed and mean differences were tested by HSD (P < 0.05). Different lowercase letters on the error bars indicate significant differences between the treatments.
