Recovery efficiency (a) and amount of nitrogen (b) in the plant derived from ammonium sulphate-¹⁵N, contents of N (c), P (d), K (e), Mg (f), Fe (g), Ca (h), Zn (i), and Mn (j) at 54 days after transplanting of rice plants (Piauí variety). Plant roots were inoculated with DSE fungi (isolates A101 and A103) or left non-inoculated (control group), and fertilised with ammonium sulphate-¹⁵N as the sole inorganic source of N. In each bar chart, values followed by the same lowercase letter do not differ between treatments at LSD t test (p < 0.05). Error bars indicate standard error of mean (n = 5)
