In order to establish the self-supplying herbage production for small-holder beef farmer in warm region of Japan, dwarf napiegrass(DL) was tried to extend for Kyushu area, by 1) establishing the efficient vegetative propagation method and stable supply method of nursery plants, 2) establishing mechanical transplanting method using vegetable-transplanter, 3) extension of several sites of Kyushu area, and 4) determining the cadmium(Cd) absorption ability of napiergrass. In this study, it was successful to establish the cell-tray nursery plants and mechanical transplanting method of DL, to determine the suitability of DL among 12 sites of Kyushu and to clarify the Cd absorption ability and utilization of digested effluent of manure from biogas plant to DL.
