The effects of spot cooling on growing ever-bearing strawberry in hydroponic cultivation during summer by spot cooling system was estimated in plasticgreenhouse located in Pyeongchang. The temperature of cooling water was controlled by heat pump and maintained at the range of 15~20 ℃. Coolingpipes were installed in root zone and very close to crown. Spot cooling effect was estimated by applying system in three cases which were cooling rootzone, crown plus root zone, and crown only. White low density polyethylene pipe in nominal diameter of 16 mm was installed on crown spot, and Stainlesssteel flexible pipe in nominal diameter of 15A was installed in root zone. Crown and root zone cooling water circulation was continuously performed atflowrates of 300 ~ 600 L/hr all day long. Strawberry yields by test beds were surveyed from Aug. 1 to Sep. 30. The accumulated yield growth rate comparedwith a control bed of crown cooling bed was 25 % and that of crown plus root zone cooling bed was 25 % and that of root zone cooling bed was 20 %. Thetemperatures of root spot in root zone cooling was maintained at 18.0 ~ 23.0 ℃ and that of crown spot in crown cooling was maintained at 19~24 ℃. Also,the temperatures of root spot in crown plus root zone cooling bed was maintained at 17.0 ~ 22.0 ℃ and that of crown spot was maintained at 19~25 ℃.
