Treatments were sown at field and arranged in a complete randomized block design with 3 replications per treatment. Individual plots consisted in four rows with 25 seeds each. Adjacent plots were separated with three spacer rows sown with untreated seeds. Data are means and standard deviations of treatment replications since no significant block effects were observed. *Data correspond to three determinations, **data correspond to three determinations performed in duplicate, and ***data correspond to six determinations performed in triplicate. Different letters indicate significant differences between treatments within the same season ( , ANOVA for complete randomized blocks). T1 (c): control seeds, T2 (+Ba): seeds treated with a suspension of B. amyloliquefaciens 109 CFUs ml−1, T3 (+Mo): seeds treated with a suspension of M. oleovorans 109 CFUs ml−1.
