Results are means ± standard deviation of three independent experiments with each treatment measured three times. Abbreviations are as follows: Organic acids (OA), ACC deaminase (ACC), Indole acetic acid (IAA), nitrogenase activity (NA), and phosphate solubilization (PS). Evaluation of the positivity to the tests; negative (−) shows absence of activity, while (+) shows lower to the highest activity (+++).
