Assessment of Low Temperature Damage on Rice Production in 1980 and 1993 in Korea

Abstract

Assessment of low temperature damage in 1980 and 1993 was attempted with the relationship between the yield index and monthly mean air temperature in Korea. Among the major climatic disasters, the frequency of low temperature damage was lower than the frequencies of drought or flood damage, but the severity in production loss was greater. In 1980, low temperature severely decreased rice yield. The yield index in 1993 was not seriously decreased though the predicted yield index was low due to low temperature.
