Erianthus (Erianthus arundinaceus) is a relative of sugarcane and is a perennial gramineae crop with high dry matter production. Current increase of in demand for bioenergy, Erianthus is expected to become a cellulosic bioenergy crop. The purpose of cultivation study is bringing out potential productivity of the crop through improving crop management. In this report, we showed the new findings gained by several field experiments, which included changing plant density for adapted high yield and harvesting system, to reduce competition between erianthus seedlings and weed at transplanting, and fertilizer management for low input and sustainability. Furthermore, we suggest the new concept of land use that bioenergy production in the Erianthus cultivating system is compatible with food production by intercropping.
