Classification and Types of Agricultural Extension Education
Agricultural extension education is broadly classified into three primary operational domains: Formal Education, Informal Education, and Non-Formal Education. Each system serves distinct learning objectives, target groups, and institutional frameworks within rural development.
- Formal Education: Institutionalized, chronologically graded, and hierarchically structured education spanning primary schools to agricultural universities (SAUs).
- Informal Education: Lifelong process whereby every individual acquires attitudes, values, skills, and knowledge from daily experiences and educational influences in their environment.
- Non-Formal Education: Any organized, systematic educational activity carried outside the framework of the formal system to provide selected types of learning to particular subgroups in the rural population.
Historical Evolution of Training and Visit (T&V) System
The Training and Visit (T&V) system of agricultural extension was developed by Daniel Benor and implemented widely in India with World Bank assistance starting in the mid-1970s. It revolutionized professional extension delivery through strict schedules and continuous training.
- Key Principles: Professionalism, single line of command, time-bound training, concentration of effort, field orientation, and linkage with agricultural research.
- Operational Structure: Contact Farmers (CFs) are selected in a phased manner; Village Extension Workers (VEWs) visit them fortnightly to transfer specific agricultural messages.
- Limitations: High recurring financial cost, rigidity in scheduling, top-down approach, and neglect of broad rural development issues beyond primary crop production.
Krishi Vigyan Kendra (KVK) and Frontline Extension Systems
Krishi Vigyan Kendra (KVK) is an integral part of the National Agricultural Research System (NARS) and acts as the premier district-level institution for technology assessment, refinement, and demonstration.
- Mandate: Conducting 'On-Farm Testing' (OFT) to identify location-specific technologies, Frontline Demonstrations (FLD) to establish production potential, and capacity development of farmers and rural youth.
- First KVK: Established in 1974 at Puducherry (Pondicherry) under the administrative control of Tamil Nadu Agricultural University (TNAU), based on the recommendations of the Mohan Singh Mehta Committee (1974).
- Administrative Control: Funded entirely by the Indian Council of Agricultural Research (ICAR), operating under State Agricultural Universities, ICAR Institutes, or Non-Governmental Organizations.
Participatory Rural Appraisal (PRA) and Extension Methodologies
Participatory Rural Appraisal (PRA) represents a growing family of approaches and methods to enable local rural people to share, enhance, and analyze their knowledge of life and conditions, to plan and to act.
- Core Philosophy: Handing over the stick to the local communities, triangulation, seeking diversity, and self-critical awareness of facilitators.
- Tools and Techniques: Social mapping, resource mapping, seasonal calendars, trend analysis, matrix ranking, and wealth ranking.
- Comparison with RRA: Unlike Rapid Rural Appraisal (RRA) where outsiders extract information, PRA emphasizes empowerment, local ownership, and continuous community-led monitoring.
Specialized Extension Projects and Institutional Frameworks in India
India has witnessed several landmark extension milestones aimed at bridging the gap between research laboratories and farmers' fields, ensuring holistic agricultural transformation.
- Integerated Rural Development Programme (IRDP): Launched in 1978-79 to provide self-employment opportunities to rural poor through asset subsidization.
- National Agricultural Technology Project (NATP) & NATP II: Funded by the World Bank to strengthen research-extension-farmer linkages and decentralized institutional capacities.
- Agricultural Technology Management Agency (ATMA): A registered society at the district level responsible for technology dissemination, ensuring decentralized, demand-driven extension delivery under the support of the Ministry of Agriculture and Farmers Welfare.
| Parameter | Individual Approach | Group Approach | Mass Approach |
|---|---|---|---|
| Target Audience | Single farmer or farm family | Small groups (15-30 farmers) | Large, heterogeneous masses |
| Examples | Farm and home visits, personal letters | Method demonstration, result demonstration, meetings | Radio, television, newspaper, campaigns |
| Cost per Contact | Very High | Moderate | Very Low |
| Persuasive Power | Extremely High | High | Low to Moderate |
| Feedback Mechanism | Immediate and direct | Immediate through interaction | Delayed and indirect |
Stands for the psychological stages a receiver undergoes when adopting an innovation: Attention (Awareness), Interest (Information seeking), Desire (Evaluation and conviction), Action (Trial and adoption).
Remember the sequence from most progressive to most traditional adopters: Innovators (2.5%), Early Adopters (13.5%), Early Majority (34%), Late Majority (34%), and Laggards (16%).
- The first Krishi Vigyan Kendra (KVK) was established in 1974 at Puducherry based on the Mohan Singh Mehta Committee report.
- Daniel Benor is recognized as the principal architect of the Training and Visit (T&V) extension system popularized globally in the 1970s and 1980s.
- ATMA (Agricultural Technology Management Agency) operates at the district level to ensure decentralized, demand-driven agricultural extension services.
- Rogers and Shoemaker defined the diffusion of innovations process as comprising awareness, interest, evaluation, trial, and adoption.
- Frontline Demonstrations (FLD) are conducted strictly under the direct supervision of scientists from NARS, primarily through KVKs and ICAR institutes.
- Confusing the establishment year of KVK (1974) with the National Extension Service (NES) launched in 1953.
- Assuming ATMA is a central government ministry department instead of a registered autonomous district-level society.
- Equating Rapid Rural Appraisal (RRA) with Participatory Rural Appraisal (PRA); RRA is extractive whereas PRA is empowering and community-led.
