영문 초록

This study was conducted to analysis a major cause of rice yield reduction in 4 research points, 1, 2, 3, and 5km, from coastline in the East Sea. There were great changes of temperature in each research point, though the average temperature a day was no difference between each research point. Each temperature in 1, 2, and 3km research points was 8, 7, and 4℃ lower than in 5km when cold salty wind was generated due to cold pool. As it was close in coastline, its soil was abundant sand components, little silt and clay soil components and lacking in cation exchange capacity(CEC). And plant height became a smaller, heading date was delayed for 3~4 days, and dry weight was reduced. Also, it was to be down percent of fertile grain. As culti-vation site was close in seaside, its decline was larger because of reduction of panicle number per hill. It was “Samdeog-byeo” that was variety adapted in cold salty wind, having yield potential more than 90% in 2km.
