Agricultural Extension and Rural Development
Agricultural Extension and Rural Development
This domain tests extension teaching methods, communication, diffusion and adoption of innovations, participatory rural appraisal and rural development institutions.
Core rules and concepts
- Extension methods are individual (farm visit, telephone call), group (demonstration, meeting, field day) and mass (radio, poster, newspaper, social media).
- Communication requires a sender, message, channel, receiver and feedback; noise reduces effectiveness.
- Diffusion of innovations classifies adopters as innovators, early adopters, early majority, late majority and laggards.
- Adoption passes through awareness, interest, evaluation, trial and adoption. Opinion leaders influence community decisions.
- Participatory approaches include PRA, RRA and farmer field schools. Institutions include KVKs, ATMA, cooperatives, self-help groups and panchayati raj bodies.
Worked example
Two hundred farmers need to learn seed treatment before sowing. A group demonstration with hands-on practice and a take-home leaflet is more suitable than 200 individual visits. Reason: seed treatment is a skill, so farmers need to see and practise the method; mass media alone can create awareness but cannot correct technique. Individual visits would be too slow and costly for this number.
Traps that cost marks
Choosing a mass method for skill training; reversing the adoption stages; treating laggards as the first adopters; confusing PRA with a formal survey; ignoring feedback in the communication process.
