This study aims to estimate yield functions of fruit-bearing vegetables in Korea by investigating the role of weather conditions as a variable. The main results of this study are summarized as follows. Firstly, the previous-year yield, current technology, and weather conditions during the growing season are found to explain current yields of fruit-bearing vegetables in Korea. Secondly, fruit-vegetable yield elasticity relating to the amount of solar radiation covers from 0.2 to 0.7. This means that changes of 10 percent in the amount of solar radiation can result in 2 to 7 percent changes in fruit- vegetable yields. Thirdly, smaller amount of solar radiation in a particular region seems to create a larger fruit-vegetable yield elasticity in that cropping region. Lastly, other climate factors such as precipitation and temperature are found to influence yield of Korean fruit-vegetables.
