  abstract = {{S}alinity poses a persistent threat to agricultural land, continuously jeopardizing global food security. {T}his study aimed to enhance sweet corn ({SC}) fitness under varying levels of salinity using indigenous biostimulants ({B}io{S}) and to assess their impacts on plant performance and soil quality. {T}he experiment included control (0 m{M} {N}a{C}l), moderate stress ({MS}; 50 m{M} {N}a{C}l), and severe stress ({SS}; 100 m{M} {N}a{C}l) conditions. {I}ndigenous biostimulants, including compost ({C}), {B}acillus sp., {B}acillus subtilis ({R}), and a consortium of arbuscular mycorrhizal fungi ({A}) were applied either individually or in combination. {G}rowth traits, physiological and biochemical parameters in maize plants, and the physico-chemical properties of their associated soils were assessed. {SS} negatively affected plant growth and soil quality. {T}he {RC} combination significantly improved plant growth under {SS}, increasing aerial (238%) and root (220%) dry weights compared to controls. {T}his treatment reduced hydrogen peroxide by 54% and increased peroxidase activity by 46% compared to controls. {T}he indigenous biostimulants, particularly {C} and {R}, enhanced soil structure and mineral composition ({K} and {M}g). {S}oil organic carbon and available phosphorus increased notably in {C}-treated soils. {F}urthermore, {RC} (437%) and {CAR} (354%) treatments exhibited a significant increase in glomalin content under {SS}. {I}ndigenous biostimulants offer a promising strategy to mitigate salinity-related threats to agricultural land. {T}hey improve plant fitness, fine-tune metabolism, and reduce oxidative stress. {I}n addition, the biostimulants improved the soil structure and mineral composition, highlighting their potential for reconstitution and sustainability in salt-affected areas. {T}his approach holds promise for addressing salinity-related threats to global food security.},
