Abstract : In the study, nutrients such as P and K, which have stress-suppressing effects, were used, as well as the use of rhizobacteria (PGPR) to reduce the negative effects of salt stress in lettuce. Seedling growth, antioxidant and some physiological parameters (leaf chlorophyll ratio, leaf membrane permeability and relative water content) were measured in lettuce seedlings exposed to salt stress. In the study, plants exposed to 150 mM NaCl application stopped their development after a certain period of time, while seedling growth was slowed down in YO41+P+K+150 mM NaCl treatment. In YÖ41+75 mM NaCl+P+K treatment, the effect of salt stress decreased. In addition, an increase in the amount of SOD, CAT, APX, POD and proline was detected in YO41+P+K+75 mM NaCl treatment. In YÖ41+P+K+150 mM NaCl treatment, the amounts of SOD, CAT, APX, POD and proline did not increase sufficiently. As a result, PGPR has been shown to be involved in K-assisted osmolyte production, ACC-deaminase and P-solubilizing activities, production of phytohormones, secretion of organic acids, acting as biocontrol agents, etc. relieves salt stress.
