ABSTRACT SUBSURFACE drain tubes were installed to re-place conventional water furrows for drainage and irrigation of potatoes. Drain spacings of 18 and 36 m were used in the experiment along with 18-m spacing of conventional water furrows. Drainage was much improved with the subsurface drains. Ir-rigation was inadequate with the 36-m spacing drains. Yield response to subsurface drainage was excellent with 18-m spacing, especially in wetter years. The subsurface drain system also resulted in more effi-cient water use by the plants than the conventional water furrow system.
