Integrated application of plant growth promoting rhizobacteria and biochar improves salt tolerance in eggplant seedlings

Biochar and PGPR applications mitigated the negative influence of salinity stress on plant growth and physiological and biochemical characteristics of eggplant seedlings, enhancing chlorophyll content, plant nutrient element uptake, and antioxidant enzyme activity. The enhanced salinity tolerance due to biochar and PGPR applications could be associated with a significant reduction in Na and Cl uptake, MDA, H2 O2 and EL and an increase in LRWC, chlorophyll content, antioxidant activity and plant nutrient element uptake.
