Salinity is one of the most critical problems for agricultural development and threatens future food safety. Therefore, we aimed to investigate root application zinc oxide nanoparticles (ZnO-NPs; 0, 50, 100 mg/L), 24-epibrassinolide (EBL; 0.02, 0.04 µM), their combinations on growth performance maize (Zea mays L.) as a model plant grown under salt stress (i.e., 5 10 dS m−1) in hydroponic system...
