High-temperature treatment for each growing season. Growth period 39%, ripening period 41%, flowering period 83% reduction in yield In an experiment conducted by the Rural Development Administration, which looked at the period when red beans were vulnerable to high temperatures, it was found that the red beans suffered the most damage from high temperatures during the flowering period (flowering period). As a result of the experiment in which the red bean growth period was divided into the growing period before flowering, the flowering period, and the ripening period (the period of ripening of the grain), the maximum temperature was treated in four different stages in a high-temperature black greenhouse. The set 'T4' section showed the highest damage rate. While the rate of decrease in yield due to high-temperature damage during the flowering period reached 83%, the yield decreased by 39% during the growing period and 41% during the ripening period. Red bean is a temperate crop native to Northeast Asia and is somewhat weak to high temperatures. As climate change continues around the world, in 2018, high-temperature damage occurred in 184,000 hectares of field crops in Korea due to the scorching heat.
