An experiment on the effect of ditch on sweet potatoes (Ipomoea batatas) production was carried out in Koya Barat Jayapura in 1994/95. Split plot design with three replications was used two local varieties from Maros and Sentani as the main plot system (one plant/ditch, long ditch, and flat system) as subplot. The size of plot was 9 x 10 m, one stek/hole with spacing and ditch 40 cm x 40 cm. The result showed that using introduced variety with flat sytem without ditch yielded 25.5 t/ha, while local variety at both of ditches yielded only 6.2 to 11.3 t/ha. Introduction of new variety can increase sweet potato production regardless of using ditch
