    • The Potato Seed System in Uganda- an end-user PerspectiveJ First Bio-Innovate Regional Scientific Conference United Nations Conference Centre (UNCC-ECA) Addis Ababa, Ethiopia, 25-27 February 2013
    • Introduction and rationale• Potato (solanum tuberosum) is important for food security and livelihoods• However the sub-sector is hampered by low productivity brought about mainly by poor planting material.• Multiplication, distribution, maintaining standards, monitoring quality are essential in maintaining high quality planting material as seed for next generation’s crop in the face of other stresses.
    • Introduction and Rationale• Despite the importance of quality seed systems for potato productivity, it is ill defined in Uganda.• This situation makes scientific interventions difficult to implement• Study was conducted to understand existing systems of seed potato from the end-user perspective• Establish preferred quality characteristics, costs of acquiring planting material and WTP for quality attributes.
    • Data and methods• Data collected from a stratified sample of 181 potato farmers in Eastern and Central Uganda• Results reported here are for Kapchorwa district• Leading producer of potatoes in Eastern Uganda.• Analysis using STATA 12 – Descriptive analysis (Percentages and means) – Robust regression (Parameter estimates for WTP)

    • While there are benefits to Time taken to Annually 38.0renewing seed every so often renew seedthe majority of farmers After 2years 30.0interviewed mentioned they After 3years 18.0renewed seed once a year, Every 3mnths 8.0after two years or even after Every 6mnths 6.0three years. Type of seed Certified 23.5 Not certified 76.5Reasons: Larger proportion of planting materialHigh cost of renewal exchanging hands was informal and of& unknown quality standardinaccessible improved seed If the situation is persists then we should expectsource. both the quality and quantity of harvest to decline over the years unless the people concerned with legislation, quality control and enforcement step up to the front
    • Conclusions• Smallholder production• Largely informal• A lot of recycling uncertified planting material• Lack of variety identify• Poor monitoring for quality>>> Low productivityOver 72% of farmers produce, exchange and sell potato seed.Those who sold were also willing to pay a premium for quality seed.Tuber yield and marketability are key attributes.
    • • There still exists opportunity to improve potato productivity given: – Appropriate varieties to address end-user needs of tuber yield and marketability (generated, disseminated) – Access to quality planting material (and quality controlled) – Private sector involvement in reducing informal exchange thus providing quality planting material
