Accumulation of Si (a) and Mn (b), Mn uptake efficiency (c) of type II energy cane (Saccharum spontaneum L.), cultivated in sufficient and deficient nutrient solution of Mn in the absence (-Si) and in the presence (+ Si) of Si. **Significant at 1% probability; *significant at 5% probability, and.^ns non-significant by the F-test. Different lowercase letters compare Si conditions under the same Mn condition, while different uppercase letters compare Mn conditions under the same Si condition (p < 0.05 by Tukey’s test). Bars represent the standard error of the mean, n = 5
