Agricultural Economics, Farm Management and Marketing
Expect cost classification, simple profitability ratios, minimum support price and marketing channel questions.
Core rules
- Fixed costs do not change with output: land rent, interest on capital, depreciation, permanent labour, insurance. Variable costs change with the enterprise: seed, fertilizer, pesticide, casual labour, irrigation charges, fuel.
- Gross income = yield × price. Gross margin = gross income − variable cost. Net income = gross income − total cost. Benefit–cost ratio = gross income ÷ total cost; a ratio above 1 means profit.
- Depreciation by the straight-line method = (original cost − salvage value) ÷ useful life.
- MSP is announced before the season to protect growers from a price crash; it is not a guarantee of profit if yields are low.
- Marketing: channel length matters. A short channel (producer to consumer or to a retailer) gives the farmer a larger share; long channels with commission agents, wholesalers and retailers widen the price spread.
- APMC markets, e-NAM electronic trading, farmer producer organizations and contract farming are common institutional answers in the paper.
Worked example
A farmer harvests 30 quintals of soybean and sells at ₹2,500 per quintal. Variable cost is ₹45,000 and fixed cost ₹15,000. Find net income and the B:C ratio. Reasoning: gross income = 30 × 2,500 = ₹75,000. Total cost = 45,000 + 15,000 = ₹60,000. Net income = 75,000 − 60,000 = ₹15,000. B:C ratio = 75,000 ÷ 60,000 = 1.25, so each rupee spent returns ₹1.25.
Traps that cost marks
- Treating land rent or depreciation as a variable cost.
- Dividing total cost by gross income instead of the reverse for the B:C ratio.
- Assuming a higher MSP always means a higher net income.
- Ignoring commission and transport when comparing marketing channels.
