Description
Summary:SummaryTwo different cultivation systems, aeroponics and hydroponics in greenhouse beds, were compared for the production of potato minitubers. Plants in the aeroponic system showed increased vegetative growth, delayed tuber formation and an extended vegetative cycle of about seven months after transplanting. Therefore in 1999, two production cycles were obtained with the hydroponic system, but only one with the aeroponic system. However, compared with total production in hydroponics, the tuber yield per plant in the aeroponic system was almost 70% higher and tuber number more than 2.5 fold higher. Average tuber weight was reduced by 33% in the aeroponic system. Advantages and possible problems with the aeroponic system for minituber production are discussed.
