Considering the effect on Mg, the treatment with CaP–HS was weakly significant ( p = 0.037).
Considering the effect on Mg, the treatment with CaP–HS was weakly significant ( p = 0.037).
On the other hand, a negative trend for HS, although not statistically significant, was recorded for both the treatments with HS, i.e., HS alone and in combination with CaP ( Table 2 ).
The Mg level in root was significantly modulated by CaP and HS factors ( p < 0.001, p < 0.05), showing a decreasing trend in concentration in the presence of HS if compared to control or CaP alone, which instead slightly increased Mg content ( Figure S2 ).
