^aMacroelements: C and N = %; Ca, K, Mg, P, and S = g/kg of grain. Microelements = mg/kg of grain. Data are the mean of three plots for each condition (n = 3). Values in the same row with different letter are significantly different according to Tukey’s test (P > 0.05). ^bThe four conditions, under high basal chemical N fertilization, was as follow: C1, control; C2, two applications of calcium nitrate as top dressing (TD); C3, T. harzianum T34 (T34); and C4, T34 plus two applications of calcium nitrate as TD. ^cSignificant effects were determined by a two-way analysis of variance (ANOVA) for T34, TD, and the interactions between both factors (T34 x TD) (Tukey’s test, P < 0.05), ns: no statistical differences.
