Abstrakt: Salinity is a critical abiotic stress which adversely affects crop productivity worldwide. A pot experiment was carried out to assess the response of acidulated cow dung (ACD) along with or without Bacillus sp. MN54 for promoting the growth and antioxidant activity of maize under normal and saline soil conditions. The experimental design consisted of salinity levels (ECe 1.5, 6, and 12 dS m−1) established via sodium chloride (NaCl) salt, along with endophytic strain MN54 and ACD addition (2.5%). Results showed that salinity negatively influenced the growth and yield of maize, but the combined application of organic input and bacterial strain Bacillus sp. MN54 significantly improved root and shoot fresh weight (73 and 69%), dry biomass (49 and 57%), physiological attributes (2 times increase) soil as compared to control soil. Similarly, higher (2 ×) uptake of NPK and maximum colonization of rhizosphere and root, shoot was observed through the combined application of ACD and Bacillus sp. MN54 relative to control. The findings of this study revealed that acidulated amendment along with endophyte MN54 reduced the oxidative stress and improved antioxidant enzymatic activity by plant-rhizosphere colonization, which could be an effective and sustainable approach for better growth, physiological, biochemical, and nutritional attributes, and yield characteristics of maize grown in saline conditions.
