  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. 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, DAE days after emergence
  3. aRepresent maximum water deficit. Common beans cv. Grafite and Bonus (1) were cultivated under two water regimes (continuous irrigation CI and water deficit WD induced after flowering)
