Nano-priming as emerging seed priming technology for sustainable agriculture

Abstract

Agriculture is threatened by climate change and by the depletion of resources and biodiversity. Exploring new farming methods is needed to increase crop production and ensure food quality and safety in a sustainable way. Nanotechnology is an emerging trend that contributes to sustaining agricultural production. Seed nano-priming helps improve seed germination, seedling emergence, growth, and yield by resisting various plant stresses. Nano-priming is a more effective method than any other seed preparation method. Studies have shown several benefits of using seed nano-priming. By regulating biochemical pathways and the balance between reactive oxygen species and plant growth hormones, nano-priming helps increase resistance against stresses and diseases with the limited use of pesticides and fertilizers.Moreover, nano-priming prevents the continued damage caused by conventional agriculture, resulting in an environmentally safer system for farmers and consumers. The present review provides an overview of developments in the field, showing the challenges and possibilities of using nanotechnology in seed nano-priming to contribute to sustainable farming practices.
