Water deficit stress is a critical constraint on global crop productivity, particularly in arid and semi-arid regions, where it severely compromises plant growth, yield, nutritional quality. Sustainable strategies to enhance resilience under such conditions are urgently needed. Nano-silicon (Si-NPs) sulfur (S) have emerged as promising amendments for mitigating abiotic stress, but their synergistic potential alleviating water oilseed crops like canola (Brassica napus L.) remains underexplored. This study investigated the combined effects of Si-NPs (0, 100, 200, 300 mg kg⁻1) 75, 150 S morphological, physiological, responses three levels (0.8, 0.6, 0.4 field capacity). Results demonstrated that significantly reduced photosynthetic efficiency, biomass accumulation, yield components. However, application counteracted these adverse effects. Specifically, 100 kg⁻1 increased shoot root weights by 19.3% 22.9%, respectively, compared control. The most effective treatment-200 with 75 kg⁻1-enhanced chlorophyll (1.76 g⁻1 FW), carotenoids (0.51 phosphorus uptake (0.85%), silicon accumulation shoots (4.3%), while reducing lipid peroxidation (malondialdehyde: 23.53 µg FW). These findings highlight role improving drought enhancing capacity, nutrient homeostasis, oxidative mitigation. provides actionable insights integrating nano-enabled sustainable management practices bolster productivity water-scarce agroecosystems. Future research should validate results elucidate molecular mechanisms driving stress-adaptive responses.
