Magnetic and microbial priming promotes faster and more consistent seed germination. Pre-sowing treatments regarded as worthwhile techniques against salinity stress. The main objective was to evaluate the stress adaptive response of maize seeds under improved pre-sowing strategies. Magnetic and microbial priming improves the physio-biochemical traits of maize seeds and alleviate the detrimental effects of salt stress by triggering the plant's defense mechanism. Seeds bio-priming was performed with Burkholderiaphytofirmans, Bacillus subtilis and magneto-priming. NaCl induces plant poisoning by storing high levels of Na+ and Cl- in plants. B. subtilis optimizes plant development and reduces biochemical damage under salinity. Current research includes the study of physical and biochemical parameters. Leaves were assayed for reactive oxygen species (ROS) scavenging enzymes. Biochemical profile like proline, POD, CAT, SOD and MDA plant biomarkers were analyzed to check the impact of salt stress. Our findings suggest that biophysical treatments stimulate the plant's defense mechanism by triggering hydrogen peroxide (H2O2) formation, leading to a faster and better response to abiotic stress. Magnetic bio-stimulation improves the physiological traits (chlorophyll content, leaf area, height of plant, fresh and dry weight of roots and shoots). The metabolite profile were also documented by hyphenated technique LCMS. Priming treatments like these are economical, fast and environment friendly for the sustainable agriculture development to alleviate various abiotic stresses and crop improvement.
