Plant nutrient uptake in different arbuscular mycorrhizal fungi (AMF) and water amount treatments. Different lower letters denote the significant differences in shoot and root nutrient uptake according to Duncan’s post hoc test; Shoot I and II designate plant materials collected at the mowing and harvest stages, respectively. Different upper letters denote the significant differences in total nutrient uptake according to Duncan’s post hoc test. If no significant difference was found among treatments, no letter is indicated
