Banana Farm Economics and Records
The four numbers that decide whether a banana block is a business or a hobby.
Bananas can be highly profitable and can also consume cash for a year before returning anything. The difference is knowing your numbers before you plant.
Yield benchmarks#
| System | Plant crop (t/ha) | First ratoon (t/ha) | Notes |
|---|---|---|---|
| Subsistence / low input | 8–18 | 10–20 | Rainfed, minimal inputs |
| Smallholder improved | 18–30 | 22–35 | Clean material, mulch, basic nutrition |
| Commercial well-managed | 30–45 | 35–50 | Full programme, irrigation, protection |
| Export elite | 40–60 | 45–65 | Precision nutrition, intensive leaf protection |
| Plantain (French/Horn) | 15–35 | 18–40 | Highly site dependent |
| Processing types (Saba etc.) | 25–45 | 30–50 | Robust, tolerant of poorer sites |
Yield components (useful for forecasting)#
Yield (t/ha) = plants/ha × stems harvested per plant per year
× bunch weight (kg) × harvest index
Example:
1,667 plants/ha × 1.15 harvests/yr × 22 kg = 42.2 t/ha/yrEvery term is something you manage: density (calculator), ratoon vigour (desuckering, nutrition) and bunch weight (water, K, leaf protection).
Cost structure#
Establishment year (per hectare)#
| Category | Typical share | Range of drivers |
|---|---|---|
| Planting material | 15–30% | Tissue culture vs suckers; number of clones |
| Land preparation | 10–20% | Slope, compaction, clearing requirements |
| Irrigation infrastructure | 15–35% | Distance to water, system type, filtration |
| Fertiliser, lime, soil ameliorants | 10–20% | Soil test results; organic matter |
| Plant protection | 5–15% | Disease pressure; residue requirements |
| Mulch and weed control | 5–10% | Whether mulch is bought or produced |
| Labour (establishment) | 15–25% | Local wages |
| Windbreak, fencing, drainage, lanes | 5–15% | Site quality |
| Design, certification, contingency | 5–15% | Contingency should be 10–15% on its own |
Steady-state operating costs (per hectare per year)#
| Category | Typical share | Notes |
|---|---|---|
| Labour | 35–50% | Usually the largest single cost |
| Fertiliser and amendments | 12–20% | Driven by soil test and yield target |
| Plant protection | 8–20% | Highly variable — Sigatoka pressure dominates |
| Irrigation (energy + water) | 5–15% | Pumping hours and tariff |
| Packaging and post-harvest | 5–15% | Boxes, liners, treatments, packhouse labour |
| Maintenance, depreciation | 5–10% | Equipment, irrigation replacement |
| Certification, administration | 2–6% | If certified |
| Contingency | 5–10% | Always include it |
Unit costs#
Work in cost per kilogram, because that is what gets compared to price:
Cost per kg = total annual cost ÷ total kg marketedA well-run block might land at 0.10–0.25 of the farm-gate price per kg in a good season; anything near or above the price is a warning.
Revenue#
| Item | What to use |
|---|---|
| Farm-gate price | Net of freight, commission, packaging — not the headline market price |
| Grade-out % | Percentage of tonnage that achieves your target grade |
| Marketable yield | Total yield × grade-out % |
| Secondary revenue | Second-grade fruit, processing sales, intercrop income, mulch sold |
| Price seasonality | Prices often swing 30–100% across the year — plan planting dates to hit the good windows |
Revenue = marketable yield (t) × net farm-gate price (t)
Gross margin = Revenue − variable costs
Net margin = Gross margin − fixed costsBreak-even#
Break-even yield (t/ha) = total cost per hectare ÷ net price per kg ÷ 1,000
Break-even price = total cost per hectare ÷ marketable yield (kg)Example: total cost €18,000/ha, expected marketable yield 30,000 kg, net price €0.70/kg.
- Break-even yield at €0.70/kg = 18,000 ÷ 0.70 = 25.7 t/ha
- Break-even price at 30 t = 18,000 ÷ 30,000 = €0.60/kg
If your realistic yield is 30 t and price €0.70, you have margin. If either slips 20%, you are close to break-even — which is why price seasonality and yield reliability matter more than either one alone.

Cash-flow timing#
| Period | Cash position | What to have ready |
|---|---|---|
| Months −6 to 0 | Outflow | Establishment capital |
| Months 0–6 | Outflow only | Operating cash for fertiliser, labour, irrigation |
| Months 6–12 | Outflow continues | Protection costs peak as canopy develops |
| Months 10–13 | First revenue | First harvest — usually not enough to cover the year |
| Year 2 | Revenue exceeds operating cost | Ratoons give higher yields at lower establishment cost |
| Years 3–5 | Best margins | Mature ratoons, amortised infrastructure |
The classic failure: capital runs out in month 9, with the crop in the ground and no way to buy fertiliser or pay the harvest crew. Budget 14 months of operating cash plus a 15% contingency before planting a single hectare.
The records system#
You cannot manage what you do not record. Minimum viable set:
Field log (per block, per month)#
| Record | Why it matters |
|---|---|
| Stand count and replacements | Real denominator for all rates |
| Desuckering dates and sucker count | The main controllable yield factor |
| Fertiliser: product, rate, date, area | Cost control and diagnosis |
| Irrigation: hours, meter reading, events | Largest variable input in many systems |
| Sprays: product, FRAC group, rate, area, operator | Resistance management and compliance |
| Leaf-area or disease assessment | Links protection to outcome |
| Weather extremes | Explains anomalies |
Harvest log (per block, per event)#
| Record | Why |
|---|---|
| Date, days from flowering, block | Calibrates your maturity model |
| Number of bunches and total weight | Yield per stem and per hectare |
| Average bunch weight | Best single performance indicator |
| Grade-out % by category | Links field practice to revenue |
| Labour hours and cost | Cost per tonne |
| Destination and price received | Actual net price, not quoted price |
Financial log (monthly)#
Income by product · variable costs by category · fixed costs · cash balance · forecast for next 3 months.
Profitability levers ranked#
| Lever | Typical impact on margin | Difficulty |
|---|---|---|
| Protect the leaf canopy | High — disease protection is the largest yield lever | Medium (costs money) |
| Water at flowering and filling | High | Medium (infrastructure) |
| Sucker discipline (1 + 1) | Medium–High, and free | Low |
| Correct spacing and uniform stand | Medium | Low if done at planting |
| Grade-out improvement | High — same tonnage, better price | Medium (handling discipline) |
| Hit seasonal price windows | Medium–High | Medium (planting date) |
| Reduce labour waste | Medium | Medium |
| Right-size fertiliser to soil test | Medium (saves cost and raises yield) | Low |
| Reduce irrigation energy | Low–Medium | Low (scheduling) |
| Certification | Variable | Costly; only where the market pays |
Risk register#
| Risk | Impact | Financial buffer |
|---|---|---|
| Price collapse at harvest | Revenue −20 to −50% | Offtake agreement; staggered planting |
| Drought at flowering | Yield −20 to −40% | Irrigation; mulch |
| Disease outbreak | Yield −15 to −60% | Insurance where available; resistant clone; sanitation |
| Labour shortage at harvest | Fruit lost in the field | Trained backup crew; incentive scheme |
| Input price inflation | Cost +10 to +30% | Forward purchasing; contingency |
| Water restriction | Yield and/or infrastructure idle | Diversified water source |
| Certification suspension | Market access lost | Internal audit discipline |
