Titanium Dioxide Nanoparticles and its Impact on Growth, Biomass and Yield of Agricultural Crops under Environmental Stress: A Review

IndraJeet Chaudhary and Vivek Singh

Anthropogenic activities of developing and developed countries caused environmental pollution. Environmental pollution causes stress to plants and agricultural yield loss and also imbalance the global food security. Titanium dioxide (TiO₂) is considered as a beneficial element for plant growth and development and also one of the most widely used in the consumer products, agriculture and energy sectors. Titanium dioxide (TiO₂) applied via roots or leaves at low concentrations has been documented to improve crop performance through stimulating the activity of certain enzymes, enhancing chlorophyll content and photosynthesis, promoting nutrient uptake, strengthening stress tolerance and improving crop yield and quality. Widespread application of titanium dioxide nanoparticles caused damage to organisms and ecosystems. For a better understanding of TiO₂ nanoparticle toxicity in living organisms may promote risk assessment and safe use practices of these nanomaterials. This review summarizes the beneficial effect of TiO₂ nanoparticle on plant growth and development and its protective role against abiotic and biotic stress.
