  1. Means (n = 4) from a same column followed by different capital letters and from same row followed by different letters are significantly different (p ≤ 0.05, LSD test)
  2. Common beans cultivars Grafite and Bonus grown in two different regimes of water (continuous irrigation at 24% of humidity CI; water deficit (WD) induced after flowering until 13% humidity)
  3. Control non-inoculated, R. tropici inoculated with Rhizobium tropici (‘BR322’, ‘BR520’, and ‘BR534’), R.tropici co-in co-inoculation with R. tropici and H. seropedicae (HRC54) and humic acids-like, N-fertilizer non-inoculated and with urea application
