Abstract
A glasshous experiment was carried out in 2002 to evaluate growth differences between two wick types, and to determine the optimum number of wicks in a wick-based hydroponics for production of 'Dejima' seed potatoes (Solanum tuberosum L.). The six minitubers ($7.0{\pm}0.2g$/tuber) produced through aeroponics were planted in a polystyrene box (51 cm long $\times$ 31 cm wide $\times$ 20 cm high) containing growth medium (perlite+peatmoss 1:2, v/v mixtures). Before the boxes were filled with the medium, 6 wicks per box were vertically and 2 to 10 wicks were horizontally installed, respectively, at the bottom of the boxes through holes. Comparing with 6 vertical wick treatment, 6 horizontal wick treatment increased the number of tubers per plant, but decreased average tuber weight. Yield of tubers greater than 5 g (seed potatoes) was not significantly affected by wick type. As the number of the horizontal wicks per box was increased from 2 to 6, the number of seed potatoes increased from 2.8 to 8.0/plant and then leveled off. Average tuber weight increased with increasing the number of the wicks up to 8 and then leveled off. As the number of the wicks per box was increased from 2 to 6, seed potato yield increased from 1.81 to 6.59 kg/$m^2$ and then slowly increased up to 10 wicks per box, reaching 12.9 kg/$m^2$. The results indicate that installing 8 wicks per box ($0.16m^2$) horizontally for the wick culture system in production of 'Dejima' seed potatoes is beneficial considering seed potato yield, cost of wicks, and convenient filling with medium.
