Extension and Farm Management
Extension and Farm Management
This domain tests extension teaching methods, adoption and communication, together with farm planning, budgeting and records. Questions often ask which method suits a particular audience or how to compare a change in practice.
Core rules
- Extension methods are individual (farm visit, office call), group (demonstration, method demonstration, field day) and mass (radio, television, print, social media). Mass media create awareness; demonstrations teach skills.
- Adoption passes through awareness, interest, evaluation, trial and adoption. Innovativeness categories include innovators, early adopters, early majority, late majority and laggards.
- Farm management uses complete budgets, partial budgets, cash-flow statements and enterprise records. Depreciation spreads the cost of durable assets over their useful life.
- A partial budget compares added costs and reduced returns against added returns and reduced costs for a proposed change.
Worked example
A farmer considers a new sprayer costing Rs 20,000 with a 5-year life. Expected added returns are Rs 35,000 per year; added operating cost is Rs 15,000 per year; depreciation is Rs 4,000 per year. Added cost = 15,000 + 4,000 = Rs 19,000. Net benefit = 35,000 - 19,000 = Rs 16,000 per year. The change is economically favourable if risk and timeliness are acceptable. The reasoning includes depreciation because it is a real annual cost of the asset.
Traps
Do not use mass media to teach a complex skill; use a demonstration. Adoption is a process, not a single decision. Partial budget is not a complete farm budget. Ignoring depreciation overstates profit. Records must be dated and consistent; memory-based estimates are weak evidence.
