Agricultural Economics, Farm Management and Marketing
This domain tests cost of cultivation, gross and net income, benefit-cost ratio, fixed and variable costs, farm planning and marketing channels. Numerical questions usually require separating costs correctly and interpreting the result.
Core rules and concepts
- Variable costs change with the level of production (seed, fertilizer, labour, fuel). Fixed costs do not change easily in the short run (land revenue, depreciation, permanent labour).
- Gross income = yield × price. Net income = gross income − total cost. Total cost = variable cost + fixed cost.
- Benefit-cost ratio (BCR) = gross income ÷ total cost. A BCR above 1 indicates that gross returns exceed total cost.
- Marketable surplus is production minus family consumption and other non-sold uses. Marketing channels move produce from farmer to consumer through intermediaries or direct sales.
Worked example
A farmer gets gross income of ₹80,000. Variable cost is ₹45,000 and fixed cost is ₹15,000. Total cost = 45,000 + 15,000 = ₹60,000. Net income = 80,000 − 60,000 = ₹20,000. BCR = 80,000 ÷ 60,000 = 1.33. The reasoning is to include both variable and fixed costs before calculating net income and BCR.
Traps that cost marks
Do not call gross income net income. Do not omit fixed costs from total cost when the question asks for profit. Do not treat minimum support price as the actual price received in every market. Do not confuse yield with income; price is needed.
