  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 were cultivated under two water regimes (continuous irrigation CI and water deficit WD induced after flowering)
  3. Treatments control: non-inoculated; R. tropici inoculated 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, DAE days after emergence
