The International Potato Center (CIP) has recently developed and promoted mini-tuber production based on a novel, rustic and publically available aeroponics system. The technology is proposed as an alternative to conventional systems of pre-basic seed (mini-tuber) production that use soil-based substrates requiring bromide for sterilization. Previous research has shown that the aeroponics technology is potentially efficient for specific potato cultivars. The overall objective of this study was to evaluate plant growth and mini-tuber
