Agricultural Economics and Farm Management
Basic concepts
Agricultural economics applies economic principles to farming. Farm management decisions include what to produce, how to produce it, how much to produce and when to sell. The exam tests cost concepts, income measures, efficiency ratios and decision rules.
Measures
- Fixed costs: land rent, depreciation, interest and permanent labour.
- Variable costs: seed, fertilizer, hired labour, irrigation and plant protection.
- Total cost = fixed cost + variable cost.
- Gross income = yield × price.
- Net income = gross income − total cost.
- Benefit–cost ratio (BCR) = gross income ÷ total cost.
- The law of diminishing returns, opportunity cost and comparative advantage guide choices.
Worked example
A one-hectare rice farm has a gross income of ₹80,000, variable cost of ₹45,000 and fixed cost of ₹15,000. Total cost = ₹60,000; net income = ₹80,000 − ₹60,000 = ₹20,000; BCR = ₹80,000 ÷ ₹60,000 = 1.33. The reasoning is that total cost must include both fixed and variable costs, and a BCR above 1 indicates profit. Every ₹1 spent returns about ₹1.33.
Traps that cost marks
Omitting fixed costs or unpaid family labour from total cost; confusing gross income with net income; treating a BCR of exactly 1 as profit; and using production figures without market price.
