The aim of this study was to gain insight into the cultivation method have more yield of maize in rice field as part of crop change. The growing test was carried out to recommended variety of dent corn of Fukui prefecture; Yumesodachi. Two types of planting density were examined; method1 was standard density to use as a green forage, and method2 was low density aim to promote resistance of lodging. Comparison of planting density shaved that method1 tended to yield higher than method2. From this findings, Suitable seeding density of maize cultivation is much the same as that of green forage. Method2 didn't promote resistance of lodging however caulome tended to wide. Further, there were more insect damages and lodgings in method2. So method2 was influenced by strong wind of typhoon because of irregular dissemination. It lets to a significant decrease in yield because ordinary combine couldn't pick up Ears that had been fallen by typhoon. Future issues are to determine sowing time that less effected by insect and to establish cultivation system that prevent falling ears by lodging.
