Activity acid invertase (*CV = 7.87%) (A) and activity neutral invertase (*CV = 4.52%) (B and C) in nodules in cowpea inoculated Bradyrhizobium sp. (T1) or co-inoculated Bradyrhizobium sp. and Actinomadura sp. (T2), Bradyrhizobium sp. and Paenibacillus graminis (T3), Bradyrhizobium sp. and Bacillus sp. (T4) and Bradyrhizobium sp. and Streptomyces sp. (T5), without and with salt stress induction (0 and 50 mmol L−1 NaCl). Means followed the same letter lower (bacterial combinations) and capital (cultivation conditions) not differ statistically (p < 0.05) according to Tukey's test. *Variation's coefficient.
