The evaluated treatments were: standard inoculation by submersion; one or two inoculations by drip irrigation; nitrogen (urea) applied by fertigation; and negative controls, without inoculation or nitrogen fertilization. Leaf gas exchanges and plant growth and yield were assessed. Inoculation by irrigation is efficient for all variables, and double inoculation by the drip irrigation system stands out, increasing stem yield in 16% when compared with the negative control, without differing from the treatment with nitrogen fertilizer.  aSaccharum  asugarcane  aBactéria  aCana de Açúcar  aInoculante  aIrrigação  aBactérias diazotróficas  aBactérias promotoras do crescimento de plantas  aFixação biológica de nitrogênio  aSemiárido1 aOLIVEIRA, A.
