Agricultural Economics and Farm Management
Agricultural Economics and Farm Management
This domain tests cost concepts, farm budgeting, profitability measures, demand and supply, marketing channels and farm planning.
Core rules and concepts
- Fixed costs do not vary with output in the short run (land revenue, depreciation, permanent labour); variable costs change with production (seed, fertiliser, casual labour, fuel).
- Gross income is total receipts. Gross margin = gross income − variable cost. Net income = gross income − total cost.
- Cost concepts include Cost A1, A2, B1, B2, C1, C2 and C3; they differ in whether rent, interest on owned capital and family labour are included.
- Benefit-cost ratio = gross income ÷ total cost. Break-even output covers total cost at a given price.
- Markets are analysed through demand, supply, elasticity and price. Marketing channels describe the path from producer to consumer.
Worked example
A one-hectare crop gives gross income of ₹80,000. Variable cost is ₹45,000 and fixed cost is ₹15,000. Gross margin = 80,000 − 45,000 = ₹35,000. Net income = 80,000 − 60,000 = ₹20,000. B:C ratio = 80,000 ÷ 60,000 = 1.33. Reason: gross margin judges the crop's operating performance, while net income and B:C ratio include fixed costs.
Traps that cost marks
Calling gross margin the same as net income; omitting fixed costs from B:C ratio; treating family labour as free when the question uses Cost C; confusing price elasticity with income elasticity; ignoring marketing costs and losses.
