Nutritional Value of Irish Potatoes
Irish potatoes are not just tasty — they’re highly nutritious too. Here’s why more people are choosing them:
- High in fiber, which helps digestion and lowers cholesterol.
- Rich in Vitamin B6, Vitamin C, and antioxidants like carotenoids and flavonoids.
- Contains folate, essential for DNA synthesis and cell growth.
- Choline for brain function, aiding in memory and development.
- Packed with bone-friendly minerals, including iron, zinc, calcium, and phosphorus.
Ecological Conditions Needed
To achieve healthy growth and high yields, Irish potatoes need the following:
- Altitude: 1,500 to 2,800 meters above sea level.
- Rainfall: Well-distributed rainfall between 850 and 1,400 mm annually.
- Temperature: A cool climate of 16°C to 20°C is ideal.
- Soil: Well-drained sandy or loamy soils with a pH of 5 to 6.5. High organic matter is a plus.
Best Irish Potato Varieties in Kenya
Different varieties suit different regions and uses. Choose certified seeds that resist diseases and have good yields. Popular options include:
- Shangi
- Saviola
- Musica
- Royal
- Sitra
- Purple Gold
- Mayan Gold
- Panamera
- Evora
- Zafira
- Tigana
- Sherekea
- Ambition
- Laura
- Lady Amarilla
- Sagitta
Each variety varies in terms of maturity period, tuber size, and disease resistance.
Land Preparation and Planting Process
Start with deep ploughing to loosen the soil. Then follow with harrowing to break large clods.
- Form hilled rows and furrows.
- Use a spacing of 75 cm between rows and 30 cm between seeds.
- Use certified seeds only, as they give better yields and reduce disease risks.
To keep the soil healthy, practise crop rotation with legumes or maize to break the cycle of pests and diseases.
Proper Fertiliser Application
Timely use of fertilisers boosts potato growth:
- At planting, apply 50 kg of DAP per acre.
- Top dress after 3–4 weeks using 50 kg of CAN per acre.
- Alternatively, you can use other nitrogen-rich fertilisers like NPK during top dressing to promote leafy growth and tuber formation.
Pests and Disease Management
To avoid losses:
- Rotate crops each season.
- Remove any diseased plants early.
- Spray with approved fungicides or pesticides when signs of disease appear.
- Avoid planting in the same spot every season to reduce risk.
When and How to Harvest
Irish potatoes mature in about 4 months, depending on the variety. Signs of maturity include:
- Yellowing and drying of leaves.
- Firm tubers under the soil.
It’s best to harvest during dry weather, which helps the tubers dry quickly and reduces rot during storage.
One acre can yield 30 to 100 bags, depending on management and soil fertility.
Market Opportunities for Irish Potatoes in Kenya
The market for Irish potatoes is strong and growing. Here’s how you can sell:
- Local markets such as Gikomba, Wakulima, and major town centers.
- Hotels, schools, and restaurants which need large quantities.
- Exporters like Selina Wamucii who buy quality produce for international markets.
