Onion farming in Zambia can be a profitable agricultural business, particularly for farmers who achieve good yields, control production costs and sell their onions at favourable market prices. With proper management, farmers can generate significant revenue from relatively small areas of land.
For example, a farmer who harvests 25 tonnes of onions from one hectare and sells them at ZMW 8 per kilogram can generate ZMW 200,000 in revenue. If total operating expenses amount to ZMW 112,000, the farmer earns an estimated operating profit of ZMW 88,000 before financing, depreciation and other excluded costs.
However, actual profitability depends on production costs, market prices, yields and post-harvest losses.
Is Onion Farming a Good Business in Zambia?
Onion farming presents a commercial opportunity because onions are widely consumed in Zambian households, restaurants, hotels and food businesses.
Demand exists throughout the year, although market prices fluctuate depending on seasonal supply, imports and other market conditions.
In July 2025, the Food and Agriculture Organization (FAO) reported that Zambia had selected onions as a priority agricultural product under its One Country One Priority Product initiative. The programme aims to strengthen domestic production, storage, processing and marketing.
This recognition highlights the economic importance of onion production in Zambia, although it does not guarantee that every farming enterprise will be profitable.
Cost of Growing One Hectare of Onions in Zambia
The amount required to produce one hectare of onions depends on seed prices, fertilizer requirements, irrigation, labour and other farm expenses.
Below is an illustrative operating budget for a one-hectare onion farm.
| Expense | Estimated cost (ZMW) |
|---|---|
| Land preparation | 8,000 |
| Onion seeds and nursery | 13,000 |
| Fertilizers | 25,000 |
| Pesticides and weed control | 10,000 |
| Irrigation operating costs | 12,000 |
| Labour | 20,000 |
| Harvesting and packaging | 12,000 |
| Transportation and marketing | 6,000 |
| Contingency | 6,000 |
| Total operating cost | 112,000 |
These are illustrative budgeting figures, not verified current input quotations. They assume suitable land and irrigation infrastructure are already available. Initial irrigation installation, land acquisition, equipment depreciation and financing costs are excluded.

How Much Profit Can You Make From One Hectare of Onions?
The profit from one hectare depends mainly on how many kilograms of onions are sold and the price received per kilogram.
Suppose a farmer achieves a marketable yield of 25 tonnes per hectare.
Total harvest: 25,000 kg
Average selling price: ZMW 8 per kg
Total revenue:
25,000 kg × ZMW 8 = ZMW 200,000
Operating profit:
ZMW 200,000 − ZMW 112,000 = ZMW 88,000
This represents a hypothetical operating profit of ZMW 88,000 per production cycle before excluded costs and taxes.
Onion Farming Profit at Different Market Prices
Using the same harvest of 25,000 kg and operating expenses of ZMW 112,000, profitability changes considerably with the selling price.
| Selling price per kg | Revenue | Operating profit |
|---|---|---|
| ZMW 5 | ZMW 125,000 | ZMW 13,000 |
| ZMW 6 | ZMW 150,000 | ZMW 38,000 |
| ZMW 8 | ZMW 200,000 | ZMW 88,000 |
| ZMW 10 | ZMW 250,000 | ZMW 138,000 |
| ZMW 12 | ZMW 300,000 | ZMW 188,000 |
These prices are hypothetical scenarios, not current market quotations.
The calculations demonstrate how market prices can affect profitability even when production costs and yields remain unchanged.
Break-Even Point for Onion Farming
The break-even point is the minimum revenue required to cover production expenses.
Using the example above:
Total operating costs: ZMW 112,000
Marketable yield: 25,000 kg
Break-even price per kilogram:
ZMW 112,000 ÷ 25,000 kg = ZMW 4.48 per kg
Therefore, the farmer must sell onions for an average of at least ZMW 4.48 per kilogram to cover the illustrated operating expenses.
Selling below this amount results in an operating loss, assuming all other costs remain unchanged.
This calculation excludes initial capital investments and other costs not included in the budget.
What Determines Onion Farming Profitability in Zambia?
Several factors influence how much money farmers earn from onion production.
1. Yield per hectare: Higher marketable yields generally increase revenue, provided the additional production costs are justified. Good seed selection, irrigation and fertilizer management are important.
2. Market prices: Onion prices fluctuate throughout the year. Farmers who harvest when market supply is high may receive lower prices than anticipated.
3. Production costs: Expensive fertilizer, irrigation, labour and crop protection products can reduce profits. Farmers should maintain records and avoid unnecessary spending.
4. Pest and disease management: Thrips, fungal diseases and other crop problems can reduce bulb size and marketable yield.
5. Storage and post-harvest losses: Properly cured onions can be stored for a period after harvesting, depending on the variety and storage conditions. Poor storage can lead to rotting, sprouting and financial losses.
6. Market access: Selling directly to reliable buyers may improve returns, but transportation, grading and packaging expenses must be considered.
For farmers interested in selling when prices are more favourable, our guide on How to Time Onion Production for Better Market Prices explains the importance of planting schedules, market research and storage.
How to Make Onion Farming More Profitable
Farmers can improve profitability by focusing on both production efficiency and marketing.
- Choose suitable varieties: Select onions adapted to local growing conditions and preferred by buyers.
- Use reliable irrigation: Avoid moisture stress during bulb development while preventing excessive watering.
- Improve crop management: Maintain balanced nutrition, control weeds and monitor pests before they cause serious losses.
- Reduce post-harvest losses: Harvest mature onions carefully, cure them properly and store them under suitable conditions.
- Find buyers before harvesting: Compare farm-gate and wholesale prices and consider transport expenses.
- Keep financial records: Record all expenses, quantities harvested, selling prices and actual profits.
Rather than expanding immediately, beginners may benefit from starting on a smaller area and using their first production cycle to assess costs, yields and market opportunities.
Frequently Asked Questions
How much can I earn from one hectare of onions in Zambia?
The amount a farmer can earn from one hectare of onions in Zambia depends on yield and selling price. For example, 25 tonnes sold at ZMW 8 per kilogram generates ZMW 200,000 in revenue. After illustrative operating expenses of ZMW 112,000, the operating profit would be ZMW 88,000 before other excluded costs.
Can I make a profit growing onions on a small piece of land?
Growing onions on a small piece of land can be profitable if farmers achieve good yields and manage expenses effectively. A farmer growing onions on 0.25 hectares, for example, can still generate meaningful income, although profitability depends on actual yields, selling prices and production costs.
What is the biggest risk in onion farming?
One of the biggest risks in onion farming is market price fluctuation. Even farmers who produce high yields can experience losses when prices fall below their production costs. Poor irrigation, pests, diseases and post-harvest losses are additional risks.
Conclusion
Onion farming in Zambia can generate attractive profits when farmers achieve good yields, maintain reasonable production costs and sell at favourable prices.
However, profitability should be calculated using realistic market prices and expected marketable yields rather than assuming every harvest will produce maximum returns.
Farmers should prepare a budget, investigate potential buyers and consider the risks before investing.
