Frank Mulcahy
Seed potato agronomist who has spent a career building seed production systems in some of the world's most challenging growing environments — from Tasmania to India, the Middle East and North America.
Frank Mulcahy is an agronomist specialising in seed potato certification and seed production, with deep experience developing seed potato production systems in challenging growing environments around the world.
For much of his career he operated the field research and development programme for Australia's largest processed potato and vegetable food company. Through his independent practice — Spud Doctor — he continues to provide research and agronomic guidance to clients across the industry.
His work has taken him into the earth of Australia, New Zealand, India, Sri Lanka, Algeria, Egypt, Saudi Arabia, Tunisia, Turkey, Iran, China, Canada and the United States.
“Respect the farmers of this world, for without them, there is no world.”
Current engagements
Board Member, Potatoes Tasmania
A grower-led productivity group enhancing the productivity, profitability, resilience and sustainability of the Tasmanian potato industry — delivering projects across productivity, research, biosecurity preparedness and industry representation.
Principal, Spud Doctor
Providing independent research and agronomic advice to clients across the potato industry.
Industry Research & Extension
Active in industry research and extension projects supporting growers and the wider sector.
Selected achievements
Yield variation, mapped and managed (Precision farming) Industry-leading precision-farming outcomes: identifying within-crop yield variation and adopting land mapping (EM38), yield monitoring, aerial crop-vigour imaging (NDVI) and variable-rate irrigation.
Pre-storage seed cutting (India) Pioneered pre-storage seed potato cutting in India, recovering oversize seed tubers safely in the most favourable conditions. 100% seed recovery ex-storage · ~1M t/yr potential saving.
Seed tuber maturity chart (Methodology) Developed a seed tuber maturity chart based on day-degree accumulation — now a blueprint for maximising stem numbers in seed crops.
Awarded for innovation (Recognition) Recipient of Simplot Australia's Game-Changer Award for Innovation, the Tasmanian Agricultural Productivity Group's Research Excellence award, and an award for Outstanding Industry Contribution.
Career depth
Across two years as Simplot Australia's Seed Potato Production Manager and ten years as its Research & Development Manager, Frank led the research team and budget improving productivity and profitability for grower-suppliers to Simplot's processing facilities — overseeing around fifty potato and vegetable research projects each year — and reduced seed rejections while improving seed vigour, with downstream production gains. Simplot processes over 300,000 tonnes of potatoes a year.
He developed an early-generation seed potato programme in New Zealand, and spent four years managing the government-provided Tasmanian Certified Seed Potato Scheme (TasSeed), including the transition of growers from a field-grown supply system to a minituber-based one. He provided agronomic expertise to Technico — India's biotechnology-based seed potato company using proprietary TECHNITUBER® technology — supporting the expansion of early-generation seed production across multiple countries, drawing on more than six years' experience implementing leading-edge agricultural technologies overseas.
He has served on the Australian Processing Potato Industry Advisory Committee (2008–2014), the national research advisory committee — which apportioned the research levy across national industry challenges — and Technical Oversight Group, and the steering committee for national certified seed potato standards, whose outcome was a single national Australian standard for certified seed potatoes. He has also been an Australasian advisor to the World Potato Congress.
