ns, * and ** indicated no significant difference, significant at P ≤ 5% and P ≤ 1%, respectively. Different letters in each column indicate a significant difference at p ≤ 0.05. SWE, S.O.V., and C.V. assign to seaweed extract, source of variance, and coefficient of variation. AMF 0 and AMF 1 assign to those with no arbuscular mycorrhiza and with arbuscular mycorrhiza inoculation at 5 g kg⁻¹ of soil.
