Mean followed by the same letter in a column is not significantly different (Tukey, 𝑃>0.05).
All plants were fertilized with the recommended commercial dose of 0.75 g L⁻¹ of NO₃ : P₂O₅ : K₂O (15 : 05 : 25), calcium nitrate (100 mg L⁻¹), micronutrients (60 mg L⁻¹), and molybdenum (0.05 mL L⁻¹).
MIX: plants simultaneously inoculated with strains FCA-8, FCA-56, and FCA-60 of P. putida.
