5. 1. Variety introduction (including DUS and VCU)
2. Supply chain management for raw material
• Pre-basic, basic, certified, raw material
• Scheduling in time and space
3. Seed production
• Lab, screen-house
• Field (generations)
4. Policy Brief writing
• Stakeholder consultation
• Quantitative info gathering
5. Mechanization
• Size of operations
• “bag less” system
6. Market explorations for potato products
• Crisps, chips
• Fresh (washed, packed, branded for supermarkets

Major activities per country

7. Example India:
Improved stores: sensors and ventilation
Observations:

- Tuber temperature
- Weights and losses from respiration and water
- Percentage of rotten tubers, skin blemishes
- Fry colour (crisps, Chips

8. Example India:
Improved haulm killing methods
Methods:
- Mechanical haulm killing
- Cutting
- Flail mowing
- Pulling
- Chemical haulm killing (e.g. Reglone)
- Combination cutting or flailing and a herbicide
- Two phased harvest (lifting by windrower and
covering with soil; final lifting after some time

9. Example Vietnam, Ethiopia:
Raw material assessment
Assessments per sample (approximately 5-15 kg per sample suffices)
• Weigh 100 kg (or smaller sample)
• Grading between 45 and 90 mm (rest = local market)
• Sorting defects, blemishes, misshapen
• Shape length:width ratio (< 1.2 = crisps, > 1.5 chips/fries)
• Dry matter percentage (oven dried or under water weight)
• Peel percentage peel loss
• Sugars fructose/glucose, fry colour (USDA chart)
• Cutting chips or crisps loss in slivers
• Blanching/Frying post frying weight
• Oil post frying oil content
• Flour grind tuber and oven dry

10. Example Indonesia
Training and demonstrations
Late blight control
- Farmers’ practice: own choice fungicide sprayed every 4 days
- VegIMPACT strategy: as farmers but fungicide choice
according to Euroblight table (http://euroblight.net/ )
Nitrogen fertilizer application
- Farmers practice: (in)organic N applied > 500 kg N/ha
- VegIMPACT strategy: less N: 10 or 20 t/ha organic manure with
100, 150 or 200 kg N from fertilizer
Source of seed tubers
- Farm saved seed
- Certified seed

11. Example Vietnam
Content of the policy brief
• Increase of the number of adapted, resistant varieties suitable for different
uses, including processing through a well-funded and organized variety
introduction and breeding programme.
• The establishment of a functioning seed potato certification system to
increase the supply of healthy material and allowing tracing and tracking.
• Research into the development of diagnostics and measurements based
decision support systems to manage fertilization, irrigation and crop
protection.
• Crop growth model based agro-ecological zoning and yield gap analysis to
assess where quick wins can be achieved regarding optimal environments and
management.
• Identification of needs, testing, introduction and demonstration of machinery
to till the land, plant the seed and harvest the crop.
• Market information and studies into storage to assure a balanced supply and
demand throughout the year

12. Good Agricultural Practices in China
Improved propagation material
● Suitable varieties
● Healthy seed
Decision support for control of pests and diseases
● Weather, crop data and model based late blight
control
● Aphid trapping based insecticide application to
avoid virus transmission in seed crops
Introduction of machinery
● Planting machine
● Rotavator ridging

13. Lessons learnt
Setting up PPP in UM and NL: golden triangle:
government-research-consortium of companies
Pre-competitive applied research not always of
interest of private companies
For companies to set up and monitor a coherent
R&D takes time to achieve experience
Each partner of a consortium wants something in it
for them (dilutes the effort)
 Industries want short term not fundamental research
