Introduction Hydroponic cultivation systems using desalinated groundwater may play pivotal role in reducing freshwater consumption for irrigation. However, reliance on desalination remains unsustainable due to its high cost, energy demand, and the serious environmental impacts of brine byproducts. Producing a biofertilizer that enables irrigation hydroponics by enhancing plant halotolerance resistance salt stress offers promising solution address scarcity low soil quality arid semi-arid regions, such as Arabian Gulf. Methods This study investigates potential Bacillus spizizenii FMH45 field experiment enhance tomato production under greenhouse directly without desalination. Results discussion demonstrated FMH45-based (HB45) significantly improved physiological parameters conditions. These improvements included notable increase shoot elongation (>13%), enhanced SPAD index values (>8%), significant rises flower fruit counts (≃ 11% 22%, respectively). B. HB45 showed bacterial densities over 100-fold various organs saline prevent infiltration into internal tissues. Furthermore, HB45-treatment oxidative response evidenced stable catalase activity, an approximately 50% reduction lipid peroxidation markers malondialdehyde (MDA), 35% decrease reactive oxygen species (ROS), including hydrogen peroxide (H 2 O ). findings demonstrate holds development effective biofertilizers capable mitigating while boosting crop productivity. approach sustainable alternative desalination-dependent hydroponics, particularly Qatar.
