The Jeonbuk Special Self-Governing Province Agricultural Research and Extension Services (Director Choi Jun-yeol) urged on the 24th to pay attention to topdressing fertilization and proper moisture management for producing high-quality autumn cabbage.

The shipping season for autumn cabbage in the Jeonbuk region is mainly in mid to late November. After transplanting, potassium chloride and urea should be applied as topdressing about 15-20 kg per 10 ares at 15-day intervals, 3 to 4 times. If growth is poor or urgent nutrient supply is needed, apply type 4 compound fertilizer 2 to 3 times according to the growth condition to restore vigor.

When heading begins, the most water should be supplied during the cultivation period. Since more than 200 liters of water per 10 ares are absorbed daily, the field must be sufficiently watered. Excessive moisture worsens the occurrence of soft rot and root rot diseases. The leaf veins of cabbage thicken, reducing marketability, so careful management is required.

Also, inspect cabbage and radish cultivation fields in advance. Control diseases such as downy mildew at the early stage of occurrence using registered pesticides according to the Pesticide Safety Use Standards (PLS). Remove diseased leaves early and manage soil moisture to prevent excessive dampness.

Autumn cabbage or open-field wintering cabbage leaves begin to freeze when the temperature drops to about -3℃. Once frozen, the leaf tips dry out and die, damaging quality. Do not harvest immediately after freezing; leave them in the field to wait for temperature rise and recovery before harvesting.

Lee Jeong-im, head of the Technology Extension Division, said, "As the harvest season for autumn cabbage and radish approaches, we will strengthen on-site technical support to prevent damage by focusing on preventive control and cold damage prevention for producing high-quality autumn cabbage and radish."
