Fig 12. Hierarchical cluster analysis with standardized data of Si, C, N, and P concentrations; C:N, C:P, and N:P ratios; use efficiencies of C (CUE), N (NUE), P (PUE); and dry matter yield (DM) for pre-sprouted sugarcane seedlings under three soil water retention capacity (WRC) levels (70, 50, and 30%) and under three forms of Si supply (Si via nutrient solution [SiR], Si via foliar spraying [SiL], and Si absence [−Si]).
