Interview with Dr. Grace Mukasa
Q: Why are onions a profitable crop in Uganda?
Dr. Mukasa: Onions have a ready market every single day. Unlike some crops that depend on seasonal demand, onions are used in almost every meal. This ensures continuous demand and stable prices.
She explains further: “The profitability of growing onions in Uganda depends on good farm management. Farmers who use improved seeds, apply fertilizers correctly, and manage pests effectively often achieve very high yields.”
Additionally, onions have a relatively long shelf life compared to other vegetables, which allows farmers to store and sell when prices improve.
Q: What are the best varieties of onions in Uganda?
Dr. Mukasa: Choosing the right variety is key to success. Some of the best-performing onion varieties in Uganda include:
- Red Creole: Hardy, disease-resistant, and stores well.
- Texas Early Grano: Sweet flavor, fast maturity, ideal for fresh markets.
- Bombay Red: High yield, strong taste, popular in local markets.
She advises: “For beginners, I recommend starting with Red Creole onions. They are easier to manage and more tolerant to environmental stress.”
Q: How to grow onions successfully in Uganda?
Dr. Mukasa: Successful onion farming starts with proper planning and land preparation.
Step 1: Land Preparation
- Choose well-drained, fertile soil.
- Loosen the soil to allow bulb expansion.
- Add compost or well-rotted manure.
- Prepare raised beds to prevent waterlogging.
Step 2: Nursery Establishment
- Sow seeds in a well-prepared nursery bed.
- Water regularly but avoid flooding.
- Protect seedlings from harsh sun and heavy rain.
Step 3: Transplanting
After 6–8 weeks, transplant seedlings into the main garden:
- Space plants 10 cm apart.
- Maintain row spacing of 30 cm.
- Water immediately after transplanting.
She emphasizes: “Spacing is critical. Overcrowding reduces bulb size and overall yield.”
Q: What fertilizers should onion farmers use?
Dr. Mukasa: Fertilizer application is essential for high yields.
- Apply DAP fertilizer during planting.
- Use CAN fertilizer after 3 weeks to boost growth.
- Incorporate organic manure to improve soil health.
Balanced nutrition ensures strong root development and large bulb formation.
Q: What are the common pests and diseases?
Dr. Mukasa: Onion farmers should watch out for:
Common Pests
- Thrips
- Onion maggots
Common Diseases
- Downy mildew
- Purple blotch
Control methods include:
- Using neem-based organic pesticides
- Practicing crop rotation
- Avoiding overhead irrigation
- Regular field monitoring
“Early detection is the key to preventing crop loss,” she advises.
Q: When is the best time to plant onions in Uganda?
Dr. Mukasa: The best planting seasons are:
- March to May (first rainy season)
- August to October (second rainy season)
However, farmers with irrigation systems can grow onions all year round, giving them an advantage in off-season markets where prices are higher.
Q: How long do onions take to mature?
Dr. Mukasa: Maturity depends on the variety:
- Texas Early Grano – about 90 days
- Bombay Red – about 110 days
- Red Creole – about 120 days
Harvest when the leaves fall over and begin to dry.
Q: What is the yield per acre?
Dr. Mukasa: Average yields range between 10 to 15 tonnes per acre. With excellent management, some farmers achieve up to 20 tonnes per acre.
Q: How profitable is onion farming in Uganda?
Dr. Mukasa: Onion farming is highly profitable.
Estimated costs per acre:
- Seeds: 300,000 UGX
- Fertilizers: 1,000,000 UGX
- Labor: 1,200,000 UGX
- Other costs: 500,000 UGX
Total cost: ~3 million UGX
Revenue: 10–15 million UGX
Profit: 7–12 million UGX per acre
“Timing the market is very important,” she adds. “Selling when supply is low increases profits significantly.”
Post-Harvest Handling and Storage
Proper handling after harvest ensures quality and reduces losses.
- Dry onions under shade for 1–2 weeks.
- Remove excess soil and roots.
- Sort and grade according to size.
- Store in a well-ventilated, dry area.
Good storage allows farmers to sell later at better prices.
Marketing Strategies for Onion Farmers

Building strong buyer relationships ensures consistent income.
