Corn, sweet potato and peanut were used as intercrops on potato fields at 4 medium elevation locations, Magelang, Gondanglegi, Kepanjen and Baturiti. The result showed that there was no significant difference in yield of potato in the intercropping plots at all locations. Intercropping on potato field increased land productivity shown by data on land equivalent ratio, especially with 29 percent for potato + sweet potato at Baturiti and 27 percent for potato + corn at Magelang. There was no significant difference in total return among intercropping plots and potato monoculture plots at Magelang and Gondanglegi. Among monoculture plots. potato produced significantly higher total return than other crops in all locations, except with peanut at Magelang.
