Abstract

The application of plant growth-promoting rhizosphere (PGPR) and Gamma-polyglutamic acid (γ-PGA) has a potential role in improving plant tolerance under abiotic stress, while their combined effects remain largely unexplored. This study aimed to evaluate the effects of the joint effects of PGPR and γ-PGA on maize growth and rhizosphere microbial communities under salt stress. A pot experiment consisting of two strain treatments (CK, M10), two γ-PGA treatments (γ0, γ1) and two salt treatments (S1, S2) was performed for this purpose. The results showed that under S1 treatment, the combined application of M10 and γ-PGA could increase plant height, leaf area and dry weight by 11.27%, 36.45% and 8.39% respectively (P
