Use of aeroponics technique for potato (Solanum tuberosum) minitubers production in Kenya

November 2012

In Kenya, potato productivity is severely constrained by limited high quality seed tubers; this is precipitated by inefficiencies in various stages in the seed production system. Production of certified seed starts with meristem tip cuttings in the tissue culture. The resultant plantlets are grown in pots in the greenhouse and/or screen-house for production of minitubers (generation 0). In Kenya, production of...
