We already reported the effects of three elements (nitrogen (N), phosphorus (P) and potassium (K)) on the growth of Ryukyu Pine (Pinus luchuensis MAYR) seedlings grown by sand culture method. In this paper, the effects of these elements on the growth of Ryukyu Pine seedlings grown by water culture method were discussed. End of five months after the treatments, with or without of these elements, their main shoot length was NPK>NP>PK>NK>Non, their leaves weight was NPK>NP>PK>NK>Non, their weight of tops was in the same order as their leaves weight, and their root weight was NPK>NP>PK>Non>NK. From these results, phosphorus was most effective element among them as reported before.
