[Agricultural, Fisheries and Livestock Newspaper=Reporter Park Nara] The Chungnam Provincial Agricultural Technology Institute (Director Kim Young) recently urged on the 29th that thorough growth management is necessary for farmers due to the increased failure rate of female flowers and concerns over quality degradation in melon cultivation facilities, as the prolonged autumn rains have led to insufficient sunlight and high humidity. According to the Provincial Agricultural Technology Institute, when there are frequent cloudy days and rainfall, photosynthesis cannot proceed smoothly, leading to reduced growth vitality, and poor root establishment due to overly wet soil can cause female flowers to easily fail or significantly lower the fruit set rate. Even after fruit set, if the high-temperature and humid environment continues, fruit enlargement will be delayed, and poor formation of the surface netting (mesh) can result in deterioration.

The Chungnam Agricultural Research and Extension Services (Director Kim Young) recently urged thorough growth management for farmers due to the prolonged autumn rains, which have led to insufficient sunlight and high humidity in melon cultivation facilities, increasing the rate of female flower failure and raising concerns about quality degradation. According to the Chungnam Agricultural Research and Extension Services, photosynthesis cannot proceed smoothly on cloudy days and during frequent rainfall, leading to reduced growth vitality, and poor root anchorage due to excessive soil moisture can easily cause female flowers to die or significantly lower the fruit set rate. Even after fruit set, if the high-temperature and high-humidity environment persists, fruit enlargement will be delayed, and the formation of the surface net (mesh) will be poor, reducing marketability. Especially when humidity is high, the risk of bacterial spot and vine wilt diseases increases, making internal ...
