Fig. 5

Percentage of hemicellulose, cellulose, lignin, and non-fiber carbohydrates (NFCs) in the dry matter of Zuri guinea grass cultivated during six regrowth cycles under different phosphorus levels: deficiency (-P), sufficiency (P), and excess (+ P) in Oxisol (A, C, E, and G) and Entisol (B, D, F, and H) in the absence (-Si) and presence of silicon (+ Si, 1.5 mmol L− 1). Ns, *, ** denote the F test results as not significant and significant at 5 and 1%, respectively. Nutritional states are compared using uppercase letters, and the effect of Si is indicated with lowercase letters (Tukey test, p < 0.05). Bars represent the standard error of the experiment mean
