If you’re considering growing sweet potatoes in Nigeria, you probably want to know one thing: how long does it take to grow sweet potatoes in Nigeria? The answer depends on several factors, but generally, sweet potatoes take 90 to 150 days (3 to 5 months) from planting to harvest.
Sweet potatoes are one of the most rewarding crops to grow in Nigeria. They require minimal care, thrive in various soil conditions, and provide a highly nutritious yield. But how long does it take to grow sweet potatoes in Nigeria? On average, it takes 90 to 150 days (3 to 5 months) from planting to harvest, depending on the variety, soil quality, and weather conditions.
In this guide, we’ll break down the growth timeline, factors affecting growth speed, best planting practices, and how to achieve a faster and healthier yield.
Understanding the Sweet Potato Growth Cycle
Sweet potatoes go through different growth stages before they’re ready for harvest. Understanding this cycle helps farmers optimize their farming practices.
1. Germination and Early Root Development (0-30 Days)
- Newly planted vines or sprouts take root and begin growing.
- Shoots start developing within the first 7-14 days.
- Requires well-aerated, nutrient-rich soil for quick root establishment.
2. Vine Growth and Leaf Expansion (30-60 Days)
- Plants focus on vine and leaf production.
- Photosynthesis increases, supplying energy for tuber development.
- Requires moderate watering and protection from pests.
3. Tuber Formation and Development (60-120 Days)
- Small tubers begin forming under the soil.
- Adequate nutrients (phosphorus and potassium) are essential for tuber enlargement.
- Farmers should avoid excessive nitrogen, as it promotes vine growth instead of tuber formation.
4. Maturity and Harvest Readiness (90-150 Days)
- Tubers reach full size and begin hardening.
- Leaves start turning yellow, a sign of maturity.
- Harvesting too early reduces yield; waiting too long can cause over-mature tubers.
Factors Affecting Sweet Potato Growth Time
1. Climate and Weather Conditions
Sweet potatoes grow best in warm temperatures (21-29°C). Consistent rainfall or irrigation speeds up growth, while extreme heat or drought slows it down.
2. Soil Quality and Preparation
- Loamy or sandy soil with good drainage is ideal.
- Compacted or clay-heavy soil delays tuber expansion.
- Adding compost or manure improves nutrient availability.
3. Variety of Sweet Potato Planted
- Early-maturing varieties (90-110 days)
- Mid-season varieties (110-130 days)
- Late-maturing varieties (130-150 days)
4. Fertilization and Nutrient Management
- Apply phosphorus and potassium fertilizers to enhance root development.
- Limit nitrogen to avoid excessive vine growth.
5. Watering and Irrigation Techniques
- Regular watering is needed during the first 60 days.
- Reduce watering during the last month to prevent tuber rot.
6. Pest and Disease Management
- Common threats: sweet potato weevils, aphids, and fungal infections.
- Use organic pesticides and crop rotation for effective control.
Best Planting Season for Sweet Potatoes in Nigeria
Rainy Season vs. Dry Season Farming
- Best planting time: April to June (beginning of the rainy season).
- Dry season farming is possible with proper irrigation.
Regional Differences in Growth Time
- Northern Nigeria: May-July planting with irrigation needed.
- Southern Nigeria: March-June planting with natural rainfall support.
Step-by-Step Guide to Growing Sweet Potatoes Faster
1. Selecting the Right Variety
Choose an early-maturing variety like TIS 86/0356 for a faster harvest.
2. Proper Land Preparation
- Till the soil and create raised beds or ridges.
- Mix organic compost to boost soil nutrients.
3. Best Planting Techniques
- Use healthy vines with at least 3-4 nodes.
- Plant at a spacing of 30cm apart on ridges.
4. Efficient Watering and Fertilization
- Water every 3-5 days during the first month.
- Apply potassium-rich fertilizers after 60 days.
5. Controlling Weeds, Pests, and Diseases
- Weed regularly to prevent nutrient competition.
- Use neem oil or organic insecticides against pests.
6. Knowing When to Harvest for Maximum Yield
- Harvest when leaves turn yellow.
- Avoid damaging tubers during harvesting to extend shelf life.

Common Challenges and Solutions in Sweet Potato Farming
1. Poor Soil Conditions
Solution: Improve with compost, organic manure, and sand for better drainage.
2. Pests and Diseases Affecting Growth
Solution: Rotate crops, use resistant varieties, and apply organic pesticides.
3. Overwatering or Drought Stress
Solution: Maintain a balanced watering schedule.
4. Delayed Tuber Formation and Low Yields
Solution: Avoid excessive nitrogen and ensure adequate potassium intake.
Expected Yield and Market Potential
How Much Can You Harvest Per Hectare?
- Average yield: 10-25 tons per hectare.
- Well-managed farms can exceed 30 tons per hectare.
Market Demand and Profitability in Nigeria
- High demand in urban markets.
- Export opportunities exist, especially for processed sweet potato products.
Conclusion
So, how long does it take to grow sweet potatoes in Nigeria? The answer depends on variety, climate, soil, and care. However, most farmers can expect a harvest in 90 to 150 days with the right techniques.
Growing sweet potatoes in Nigeria takes 90 to 150 days, depending on the variety, soil quality, and farming techniques.
