| Summary: | Abstract Enhancing sustainable rice production is crucial for global food security. Here we demonstrate that 0.1 mg kg‒1selenium-engineered nanomaterials promote rice (Oryza sativa L.) tillering and yield by optimizing the rhizosphere microbial community, improving nitrogen use efficiency, and modulating plant hormones and growth-related genes. Using pot experiments with five different soils and field trials in China, we found that soil organic carbon strongly influences nanomaterial effectiveness. Field results demonstrated a 10.7% yield increase and a 309.8% rise in grain selenium concentration, with no adverse effects on soil quality. Predictive modeling calculated that selenium-enhanced agriculture could increase profits by +$231.5 ha−1, reduce CO2 emissions by 1.12 Tons ha−1, and produce selenium-rich grains ( ~ 20 μg·100 g−1) to address dietary deficiencies. Our findings highlight the potential of selenium nanomaterials to sustainably boost rice production, urging further research across diverse ecosystems to optimize their agricultural and environmental benefits. |
