기후변화 시대 콩의 건조 스트레스 완화를 위한 엽면시비 기술 연구 동향

초록

Climate change-induced drought stress severely impairs soybean growth and yield by inhibiting photosynthesis and increasing reactive oxygen species (ROS) accumulation, which leads to cellular damage. Traditional management practices, such as irrigation and soil fertilization, face significant limitations under water-deficient conditions. This review highlights foliar application as an effective agronomic strategy to alleviate drought stress in soybean cultivation. Foliar spraying of mineral nutrients—including boron, copper, iron, nitrogen, potassium, phosphorus, and zinc—as well as organic acids such as acetic acid, ascorbic acid, and salicylic acid, has been shown to enhance antioxidant activity, improve water use efficiency, and promote overall plant growth and stress tolerance. Therefore, foliar application represents a valuable tool for sustaining and improving soybean productivity under drought conditions in the context of climate change. Nevertheless, further research is needed to optimize the timing and combinations of foliar treatments for maximal efficacy.
