The Rural Development Administration of Korea has identified the flowering period of red beans as the most vulnerable to high temperatures, with damage rates peaking in temperatures 5 to 6 degrees higher than outdoors. High temperature damage during the growing season decreased yield by 39%, and by 41% during the ripening period, but the greatest decrease, 83%, was during the flowering period. The administration recommends maintaining soil moisture through irrigation and considering the cultivation of early variety red beans to reduce damage.
