[Korea Farmers' News Agency, Reporter Park Du-gyeong] In Jaesan-myeon, Bonghwa-gun, Gyeongbuk, which was busy with watermelon farming in the summer, farmers are now enjoying great joy with the tomato harvest. The Jaesan Tomato Farmers Cooperative (Representative Kim Yoon-ha, 64 years old) in Jaesan-myeon, Bonghwa-gun, introduced the Gyeongbuk Province-led joint farming model starting last year. With 26 farms joining forces to cultivate watermelons and tomatoes in a double cropping system, and by equipping themselves with a joint collection center and an automatic sorting machine, their farming methods have changed drastically. By converting open-field watermelon cultivation to greenhouse cultivation, they have advanced the harvest period, and by planting tomatoes as a subsequent crop after the watermelon harvest, income per farm has tripled, averaging 400 million won per farm.
