Key points to design your business plan

The Integrated Industrial Seed Production and Support for High-Performing Potato Varieties (Chieftain, AC Chaleur, and Kennebec) offers a commercial opportunity to develop a competitive potato seed and production business in West Africa. The technology combines the local multiplication of disease-free Elite III seed potatoes, high-performing varieties, and an integrated technical support package to supply reliable planting material and quality potatoes for fresh consumption, storage, and processing markets.

The main business opportunity lies in addressing the current market gap created by the limited availability, high cost, and delayed supply of imported potato seed. Establishing local industrial seed multiplication capacity can create a reliable supply chain for certified seed potatoes while reducing dependence on European imports. Private sector actors can develop businesses around seed multiplication, commercialization, aggregation, storage, and processing, serving a growing regional potato market.

The technology provides strong commercial advantages through the performance of its three varieties. Chieftain offers high yield potential, reaching up to 37 T/ha in local trials, while AC Chaleur provides a competitive advantage for storage and market flexibility due to its low post-harvest losses. Kennebec, with its high total solids content, is suitable for industrial processing markets such as chips and French fries. Together, these varieties enable diversification across fresh potato, seed potato, and processing value chains.

Potential investment models include establishing seed multiplication and distribution businesses, developing commercial production schemes, investing in storage and aggregation infrastructure, and building supply partnerships with processors requiring consistent-quality raw materials. Additional opportunities exist in integrated service models combining quality seed supply, technical advisory services, and production inputs to strengthen the potato value chain.

Successful implementation requires investment in appropriate infrastructure, including seed multiplication facilities, irrigation systems, storage capacity, and quality control systems. The business model should be supported by strong technical management practices, including soil-based nutrient management, integrated pest management, and improved post-harvest handling to maintain product quality and maximize returns.

The technology presents a high-growth investment opportunity by improving productivity, reducing supply risks, and expanding access to regional markets. By strengthening local seed systems and increasing the availability of market-oriented potato varieties, private sector investment can contribute to the development of a more competitive and profitable potato industry across West Africa.

Climate adaptability: Highly adaptable

Short-cycle varieties (90–105 days) are adapted to Sahelian dry-season conditions, reducing exposure to end-of-season water shortages and climate variability.

Farmer climate change readiness: Moderate improvement

The technology improves resilience through adapted varieties and improved practices, but requires access to irrigation, technical support, and inputs that may not be available to all farmers.

Biodiversity: Positive impact on biodiversity

The introduction of multiple potato varieties can increase crop diversity, but intensive production systems and reliance on a limited number of improved varieties may reduce genetic diversity if not managed.

Carbon footprint: A bit less carbon released

Local seed multiplication can reduce emissions linked to imported seed transport, but production may generate emissions from machinery, fertilizers, and irrigation.

Environmental health: Moderately improves environmental health

Integrated Pest Management (IPM) and improved agronomic practices can reduce environmental risks, although fertilizer and pesticide use require proper management.

Soil quality: Does not affect soil health and fertility

Soil testing, organic manure application, and balanced fertilization support soil health, but intensive potato cultivation can degrade soils if crop rotation and nutrient management are not followed.

Water use: A bit less water used

Potato production requires regular irrigation (25–40 mm/week), but short-cycle varieties improve water-use efficiency by completing production within a shorter growing period.

Scaling Readiness describes how complete a technology\’s development is and its ability to be scaled. It produces a score that measures a technology\’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers.

1. Seed Selection and Preparation

  • Use quality planting material: Source certified Elite III disease-free seed potatoes to ensure healthy crop establishment and high yield potential.
  • Prepare seed tubers: Plant small tubers whole, while larger tubers should be cut into pieces containing 1–3 healthy buds (“eyes”).
  • Apply suberization: Allow cut seed pieces to dry and heal for 1–3 days in a cool, well-ventilated area to reduce rotting after planting.

2. Field Preparation

  • Assess soil conditions: Conduct soil testing to determine nutrient requirements and ensure suitable conditions (well-drained soils with good organic matter content and pH between 5.0 and 6.5).
  • Practice crop rotation: Avoid fields previously planted with tomatoes, peppers, eggplants, or other nightshade crops to reduce disease risks.
  • Prepare the planting bed: Create a fine, well-prepared seedbed with ridges and incorporate approximately 10 t/ha of well-decomposed organic manure.

3. Planting and Nutrient Management

  • Plant at the right conditions: Start planting when soil temperatures reach 7–10°C or above.
  • Maintain recommended spacing: Plant seed pieces at 8–10 cm depth, with approximately 25–30 cm between plants and 75–90 cm between rows (adjust spacing depending on production objectives).
  • Apply balanced fertilization: Use soil test recommendations to guide fertilizer application. Apply NPK fertilizers as required while avoiding excessive nitrogen, which can reduce tuber development.

4. Crop Management

  • Ensure adequate water supply: Maintain consistent soil moisture throughout the crop cycle, with increased attention during early growth stages and adjustment according to plant development.
  • Perform earthing-up (hilling): Cover the base of plants with soil when they reach 15–20 cm height to protect tubers from sunlight and improve tuber development.
  • Implement Integrated Pest Management (IPM): Regularly monitor pests and diseases, including aphids, potato beetles, and early/late blight, using resistant varieties and targeted control measures.

5. Harvest and Post-Harvest Management

  • Harvest at the appropriate maturity stage: Harvest young potatoes 2–3 weeks after flowering or mature tubers once vines naturally die back.
  • Cure harvested tubers: Store harvested potatoes in dark, ventilated conditions at 10–15°C for 1–2 weeks to strengthen the skin and heal minor injuries.
  • Store under suitable conditions: Use cool, dark, and well-ventilated storage facilities with appropriate temperature and humidity control to maintain quality and reduce losses. Varieties such as AC Chaleur are particularly suitable for longer storage due to their excellent storage performance.
