onion production south korea, imported seeds agriculture, onion storage disease fungi, sustainable farming strategies, crop supply chain analysis — South Korea’s onion industry is facing a growing challenge that most people never see: heavy dependence on imported seeds and rising post-harvest losses.

This episode breaks down the agricultural and economic dynamics shaping onion production in South Korea, where reliance on foreign seed sources—particularly from Japan—has created long-term vulnerabilities in food security and domestic competitiveness.

We explore how shifts in global trade have led to rising imports and declining exports, and why fungal pathogens during storage are causing significant crop losses after harvest. The episode also examines the urgent need for domestic cultivar development, improved storage technologies, and coordinated strategies between farmers, researchers, and policymakers.

From field to storage to global markets, this is a comprehensive look at modern agriculture, supply chain resilience, and sustainable food production, revealing how one staple crop reflects broader challenges in global farming systems.
