The effects of Bacillus amyloliquefaciens on Mentha piperita grown under salt stress

Abstract

Climate change threatens agricultural areas and food supply security not only in our country but also worldwide. As a result, plants are exposed to many abiotic stresses such as salt stress, drought stress, etc. Various methods are being tried to cope with abiotic stress, but sustainable alternative methods are needed in agriculture and one of them is biological fertilizers. Microbial fertilizers such as plant growth promoting bacteria (PGPB) reduce the use of chemical fertilizers and support environmentally friendly, soil-friendly, and more economical production in agriculture. In this study, the effects of Bacillus amyloliquefaciens, defined as a salt tolerant species, on the morphological parameters of Mentha piperita, which has significant commercial value and was grown under salty conditions, were investigated. Surprisingly, Bacillus amyloliquefaciens did not significantly alleviate the effects of salt stress on M. piperita grown under saline conditions (0, 50, 75, and 100 mM NaCl) in almost all parameters except for water content.
