Consortia of Plant-Growth-Promoting Rhizobacteria Isolated from Halophytes Improve Response of Eight Crops to Soil Salinization and Climate Change Conditions

Soil salinization is an environmental problem that adversely affects plant growth and crop productivity worldwide. As alternative to the conventional approach of breeding salt-tolerant cultivars, we explored use plant-growth-promoting rhizobacteria (PGPR) from halophytic plants enhance under saline conditions. Here, report effect five PGPR consortia halophytes on eight (alfalfa, flax, maize, millet, rice, strawberry, sunflower, wheat) crops most commonly produced salinized soils To test efficiency halotolerant consortia, designed a complex matrix simulating future climate-change scenarios, including increased CO2 levels temperature. Overall, biofertilizers enhanced with respect non-inoculated control different concentrations (400/700 ppm), temperatures (25/+4 °C), salinity conditions (0 85 mM NaCl). Biofertilizers counteracted detrimental growth. Specifically, strawberry rice showed greatest positive additive response inoculation in presence salt; above-ground biomasses were 35% 3% greater, respectively, than their respective grown without salt. Furthermore, depending interaction factors (salinity × temperature) analyzed, results varied—influencing effective biofertilizer determined for each now, or future. Our findings highlight importance conducting studies consider stress realistic assessments potential climate-changed world.
