Market is short of organic and fresh potatoes from August to November in Taiwan. Therefore， some aboriginal people can produce potatoes for fresh organic market in summer by taking advantage of higher altitude where they cultivate. People can plant potato in the facility in high land during the rainy season and harvest in August to September， which produce twice as yield as those grown in the open field. It is recommended to begin to plant potatoes in the open field after the rainy season， and harvest in September to October. Additionally， the yield of potato grown in an altitude of 700m in the open field is lower than that in 2100m above the sea level. In the meanwhile， the yield per plant of different Kennebec clones grown in the elevation of 700mwas different between 145 and 279 grams， which clone 101A and 101G had higher yield. Furthermore，we collected 2 potato clones in the tribal homeland and successfully produced tubers after moving to the greenhouse in our station under high temperature environment. In another experiment， native green-skin cowpea strain 1had the highest yield among test strains， and we recommended to plant the strain singled or mixed to get the higher yield when grown in the indigenous tribe area. Planting native strains of cowpea with no irrigation， fertilization and spraying chemicals could successfully harvest pods， which is low input for organic production. So， organic native cowpea cultivation is feasible in the tribal homeland
