Abstract: The recommendation for a propagation medium of rabbiteye blueberry (Vaccinium ashei Reade) in Japan includes the incorporation of peat moss and Kanumatsuti (a volcanic ash deposit). This experiment compared the use of coal ash (clinker ash) and Kanumatsuti to peat moss as soil conditioner for rooting rabbiteye blueberry cutting. The numbers of cuttings survived and the root dry weight of plants propagated in clinker ash- peat moss mixes were almost the same as cuttings propagated in kanumatsuti- peat moss mix. While the quadratic model between the root dry weight and the clinker ash content in the medium was significant, the maximum root dry weight was estimated to reach about 0.2 g when the proportion of clinker ash in the medium was about 40%. These findings indicate that clinker ash can be used in the propagation medium of rabbiteye blueberry.
