The impact of the ENSO phenomenon causes a shift in the pattern of rainy and dry season. This will affect the agricultural activities Kebumen regency, crop failure and decreased productivity are few of the results of such impacts. This study aims to find the exposure pattern of dryland agriculture in Kebumen regency towards ENSO phenomenon and its association with maize productivity. The Data used is the daily rainfall period of 1986-2016 from 32 observer rain stations. There are five parameters to identify exposures are early deviation and duration of a dry season, rainfall of the maize, the maize harvest, the number of rainy days in maize harvest and the method used is scoring and overlay. The pattern of high exposure to dryland agriculture tends to be in mountainous areas. The El Nino Period of 2015 does not result in dryland agriculture Significantly being exposed due to low exposure, while the La Nina period results in moderate to high exposure cleaning Because land does not require too much water. In the El Nino period of 2015, maize productivity tends to rise 43% from normal conditions. In the La Nina period in 2010, the productivity of maize dropped by 63% Compared to normal conditions.
