Pepper (Capsicum annuum L.) is an important vegetable crop in Turkey and also, salinity is big problem for some areas of Turkey. The experiment was conducted in Silifke Vocational School of Mersin University in March 10, 2022 under greenhouse. The pepper cultivar “Arena F1” was used as plant material. And mycorrhiza (Endo Roots Soluble-ERS), seaweed and bionutrient (PGPR) were used as an application. Pepper seedlings were kept in water with mycorrhiza (3 g L-1), seaweed (3 mL L-1) and bionutrient (3 g L-1)  prepared in separate containers for 2 minutes and then planted in pots in greenhouse. After planted, 200 mL was applied to each seedling from the soil twice with one-week intervals. The plants were subjected NaCl (150 mM) at early seedling growth during the 20 days. In this study, It was determined that the treatments of mycorrhiza, seaweed and bionutrient have a positive effect on plant growth, fresh weight (FW), dry weight (DW), leaf number, plant height and root length, and amount of nitrojen (N), phosphorus (P), potassium (K), calsium (Ca), magnesium (Mg) under salt stress. MDA, proline and Na contents of pepper plants increased under salt stress, and these parameters decreased due to the reduction of the negative effects of salt stress by using mycorrhiza, seaweed and bionutrients, and thus increased tolerance to salt stress.
