Overview

Randomized trial demonstrates improved plant growth under saline conditions using microbial co-inoculation, suggesting a beneficial agricultural practice.

Key Points

  • To investigate the potential of a halotolerant Bacillus strain and arbuscular mycorrhizal fungi to enhance plant growth in saline soils.
  • Isolated 30 salt-tolerant bacteria strains from the rhizosphere of Suaeda salsa.
  • Evaluated the plant-growth-promoting traits of Bacillus infantis strain 29, including ACC deaminase activity and IAA production.
  • Conducted pot experiments to assess growth impacts on Suaeda salsa, Zea mays, and Medicago sativa with and without microbial inoculation.
  • Inoculation with Bacillus infantis strain 29 and AMF significantly increased fresh weight and root length in Suaeda salsa compared to control.
  • Positive growth responses in Zea mays and Medicago sativa were also observed under combined treatments.
  • Strain 29 showed tolerance to NaCl concentration up to 10%, indicating its potential utility in saline conditions.
