Abstract Halophytes display distinctive physiological mechanisms that enable their survival and growth under extreme saline conditions. This makes them potential candidates for use in agriculture. In this research, tomato ( Solanum lycopersium Mill.) was cultivated moderately conditions two different managements involving Arthrocaulon macrostachyum L., a salt accumulator shrub: intercropping, i.e. , co‐cultivation of tomato/halophyte; crop rotation, which is grown where the halophyte previously cultivated. The effect these evaluated plants comparison with monoculture, regards to biochemical variables metabolomic proteomic profiles. Both halophyte‐based reduced soil salinity. Crop rotation enhanced photosynthesis protective at photosynthetic level. addition, both altered hormone profile antioxidant capacity, whereas reactive oxygen species over‐accumulation leaf tissues indicated establishment controlled mild oxidative stress. However, production remained unchanged. Metabolomic approaches suggest complex interactions level, driven by influence halophyte. regard, an interplay ROS/lipid‐based signalling pathways proposed. Moreover, improved associated accumulation sugar metabolism‐related compounds photosynthesis‐related proteins. Likewise, acylamino acid‐releasing enzymes, class serine‐proteases, remarkably increased managements, may act modulate capacity plants. summary, work reveals common patterns intercropping halophyte, supporting A. farming systems.
