Unavailability of certified seed tubers is a major constraint to potato production in Kenya. This compels most farmers to use planting materials from informal sources such as previous harvests, local markets and neighbours. Kenya Agricultural Research Institute (KARI), Tigoni has the national mandate to produce basic seed tubers but can only supply much less than 1% of the national seed requirements. In order to improve on the situation, aeroponics technique was introduced to enhance production of prebasic seeds from tissue culture plantlets. The aeroponics unit is still in experimental stages and is being evaluated for productivity and profitability. Some results show that aeroponics can increase production of prebasic minitubers. However, the aeroponic technology needs further and complete evaluation in terms of productivity, profitability and sustainability.


Key words: Aeroponics, certified seed, Kenya Agricultural Research Institute (KARI), Tigoni, minitubers, potatoes.
