Effects of Rhizobium inoculation on (a) dehydrogenase enzyme activity, (b) β-Glucosidase enzyme activity, (c) acid phosphatase enzyme activity, (d) acid phosphatase enzyme activity, and (e) urease enzyme activity of soils amended with essential oil (E0: No essential oil; E1: essential oil (100 mg kg−1), E2: essential oil (1000 mg kg−1) and Rhizobium inoculation (R1: Rhizobium leguminosarum biovar phaseoli F7; R2: Rhizobium leguminosarum biovar phaseoli F83; R3: Rhizobium leguminosarum biovar phaseoli Ciat 889). Values are means ± SE. Different letters indicate significant differences at p < 0.001. Post doc comparisons have been done between the different inoculation treatments.
