Salinity stress is one of the major global problems that negatively affect crop growth and productivity. Therefore, ecofriendly sustainable strategies for mitigating salinity in agricultural production food security are highly demandable. Sugarcane press mud (PM) an excellent source organic amendment, role PM not well understood. this study was aimed to investigate how mitigates through regulation rice growth, yield, physiological properties, antioxidant enzyme activities fine grown under different conditions. In study, levels (6 12 dS m-1) with or without 3, 6, 9% SPM, respectively were tested. significantly increased malondialdehyde (MDA, 38%), hydrogen peroxide (H2O2, 74.39%), Na+ (61.5%), electrolyte leakage (40.32%), decreased chlorophyll content (32.64%), leaf water (107.77%), total soluble protein (TSP, 72.28%), free amino acids (FAA, 75.27%). However, these negative effects reversed mainly plants after application. application (9%) remained most effective TSP, FAA, accumulation sugars, proline, K+, activity enzymes, namely, ascorbate peroxidase (APX), catalase (CAT), (POD). Thus, findings suggest a PM-mediated eco-friendly strategy alleviation soil could be useful plant productivity saline soils.
