Metal Oxide Nanoparticles for Crop Stress Tolerance and Yield Enhancement
This community investigates how metal oxide nanoparticles are applied to crops to improve growth, enhance tolerance to environmental stresses like drought and salinity, and increase agricultural yield.
The research centers on the synthesis and application of zinc oxide, silver, and silicon nanoparticles, often delivered via foliar spray or seed priming. A significant portion of the work examines the physiological and biochemical responses of major crops—specifically rice, wheat, and maize—to these nanomaterials under abiotic stress conditions. The literature frequently details mechanisms involving antioxidant defense systems and nutrient uptake, with a strong focus on sustainable agriculture practices. Specific applications include the use of nanofertilizers, the remediation of agricultural soils, and the targeted delivery of agrochemicals to improve plant resilience and productivity.
The community is most heavily concentrated in silicon research, accounting for 0.9% of all silicon-related papers, followed by zinc (0.7%) and silver (0.6%). Silicon also contributes the highest raw number of papers to this group, with 3,269 entries.
The community comprises 12,401 papers, published predominantly in Plants, Silicon, and Frontiers in Plant Science.
Recent work continues to focus on the specific mechanisms of stress mitigation, such as silicon oxide nanoparticles enhancing rice salinity resilience and zinc oxide nanoparticles mitigating heat stress in peppers and watermelons.
