Popular Red Onion Varieties in Africa
Red onions come in various varieties, each with unique qualities tailored to specific climates and markets:

Climate and Soil Requirements
Red onions thrive in:
- Moderate temperatures: Between 13–24°C.
- Well-drained soil: Fertile soil with a pH of 6.0–7.5 ensures optimal growth.
Onion Doctor offers soil testing services to help farmers optimize these conditions for higher yields.
Planting Red Onions
Land Preparation
Choose well-drained land with adequate sunlight. Clear debris and loosen the soil for better root development.
Seedling Production
Use seed trays or containers with a suitable potting mix. Ensure adequate moisture and warmth for healthy germination.
Planting Tips
- Spacing: 12–18 inches between rows and 4–6 inches between plants.
- Fertilization: Apply organic matter and balanced fertilizers during planting.
By following these practices, farmers can maximize their yields. Onion Doctor provides expert guidance on seedling production and fertilization techniques.
Crop Care and Maintenance
Irrigation
Consistent watering is key, but avoid overwatering to prevent root rot. Mulching helps retain moisture and suppress weeds.
Pest and Disease Management
Protect crops from common pests like onion flies and thrips by using:
- Organic or chemical controls.
- Proper crop rotation and sanitation.
Onion Doctor offers e-extension services and agronomic support to help farmers address these challenges.
Harvesting and Storage
Harvest red onions when the foliage turns yellow and falls over. Use proper curing techniques to enhance shelf life:
- Field Curing: Dry bulbs under the sun with leaves partially covering them.
- Protected Curing: Cure in a ventilated, dry area for consistent results.
Store cured onions in cool, dark, well-ventilated spaces to prevent spoilage.
Onion Doctor provides post-harvest training to ensure farmers maximize profits.
Common Challenges and Solutions
Farmers often face:
- Fungal diseases: Mitigate with fungicides and good cultural practices.
- Nutrient deficiencies: Address through soil testing and tailored fertilization.
- Pests: Use recommended pesticides and biological controls.
Onion Doctor assists farmers in troubleshooting these issues to ensure a successful harvest.
