Fig. 3From: Nanosilica enhances morphogenic and chemical parameters of Megathyrsus maximus grass under conditions of phosphorus deficiency and excess stress in different soilsTiller appearance rate (TA), tiller mortality rate (TM), tiller survival rate (TS), and number of tillers per pot of Zuri guinea grass 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 meanBack to article page
