The potato is the second most important food and cash crop after maize in Kenya. It goes without saying that the potato occupies a prime position in terms of contribution to food security, poverty eradication, and economic development. It is grown by about 800,000 smallholder farmers, employs 2.7 million actors along the marketing channels, and contributes over Kshs 50 billion to the economy. The sub-sector’s significance is seen in its great potential to further contribute to improved wealth and food security for the country; what with its productivity levels (less than 10 tonnes per hectare vis-a-vis 40 tons/ha achievable under recommended agronomic practices), coupled with the increasing demand for potato due to expanding cities.
