Nanotechnology holds transformative potential for the agricultural sector, promising enhanced crop production, protection, and sustainability. This book chapter critically examines the opportunities and challenges of deploying nanotechnology in the agri-input sector of agriculture, emphasizing the need for robust research and regulatory frameworks. Nanotechnology offers a wide range of applications in agriculture, providing innovative solutions for enhancing crop nutrition, improving pest control and delivery systems, and promoting sustainable farming practices. The development and adoption of nano-fertilizers, nano-pesticides, nanosensors, and other nano-enabled products have the potential to revolutionize the agricultural industry. However, it is essential to consider the environmental and health impacts of these technologies and establish regulatory frameworks to ensure their safe use. Continued research and development in agricultural nanotechnology will contribute to more efficient, sustainable, and resilient food production systems.
