It serves as a digital platform for knowledge exchange between researchers, extension workers, and farming communities, overcoming the barriers of distance, time, and limited manpower. Through the use of computers, the internet, mobile applications, and social media, cyber extension enables farmers to access real-time information on weather, market prices, pest management, government schemes, and new technologies. This approach enhances the efficiency, speed, and reach of agricultural advisory services, making them more interactive and farmer-centric. Cyber extension tools such as video conferencing, online expert systems, and mobile advisories promote participatory learning and decision-making among farmers. Despite its potential, challenges such as poor digital literacy, inadequate infrastructure, and limited internet access in rural areas restrict its full implementation. The study emphasizes that strengthening ICT infrastructure, training farmers, and integrating traditional extension with cyber platforms can lead to more inclusive and sustainable agricultural development.en-USCyber Extensione-ExtensionICTDigital AgricultureInformation DisseminationFarmersSustainable DevelopmentBook chapter
