AB Rice is one of the most important crops in the world and is considered a strategic cropfor food security. Furthermore, the excessive use of chemical fertilizers to obtain high yields causesenvironmental problems. A sustainable alternative includes taking advantage of beneficial bacteriathat promote plant growth. Here, we investigate the effect of five bacterial biofertilizers fromhalophytes on growth, and we investigate photosynthetic efficiency in rice plants grown under salineconditions (0 and 85 mmol L−1 NaCl) and future climate change scenarios, including increasedCO2 concentrations and temperature (400/700 ppm and 25/+4 ◦C, respectively). Biofertilizers1–4 increased growth by 9–64% in plants grown with and without salt in both CO2- temperaturecombinations, although there was no significant positive effect on the net photosynthetic rate of riceplants. In general, biofertilizer 1 was the most effective at 400 ppm CO2 and at 700 ppm CO2 +4 ◦Cin the absence of salt. Inocula 1–5 also stimulated plant length at high CO2levels without salt. Finally,the positive effect of biofertilization was attenuated in the plants grown under the interaction betweensalt and high CO2. This highlights the significance of studying biofertilization under stress interactionto establish the real potential of biofertilizers in the context of climate change conditions.
