Nanotechnology (NT), based on matter at nanometre scales, has emerged as a transformative field in agriculture by manipulating atomic and molecular levels to innovate novel associations with unique properties. Due to global population growth and worsening environmental conditions, traditional agriculture confronts unprecedented challenges. While fertilizers and insecticides have met the increasing demands of crop production, their overuse hinders the sustainable agricultural. It is crucial to explore the innovative methods that reduce dependence on harmful chemicals to strike a balance between productivity and environmental. Agriculture, vital for economic growth and food security globally, requires sustainable practices to ensure long-term viability and conservation efforts. The integration of nanotechnology into agronomy has been developed as a crucial strategy to tackle modern challenges and promote sustainable agriculture. Nano-biotechnology has revolutionized farming through innovations, for example, nano-fertilizers, nanocarriers, nano-biosensors, and nano-pesticides, contributing significantly to crop production and protection. Nanoparticles in agriculture enhance nutrient absorption, stress tolerance, and optimize plant performance through controlled release of nutrients and bioactive compounds. Future advancements focus on developing novel nanoparticles with specific functions and interactions in agro-ecosystems.
