The National Agricultural Food Research Organization (NARO) has formulated "Standard Operating Procedure (SOP)", which outlines cultivation management techniques suited to the characteristics of the Tohoku region, with the aim of establishing a production and supply system for onions in the Tohoku region and for increasing the share of onions produced domestically as well as providing a year-round supply of onions for commercial processing with a high import ratio. This SOP will be useful for the stable supply of domestic onions.
Overview
Although onion is one of the highly consumed vegetable, the production area is concentrated in certain areas such as Hokkaido, Saga and Hyogo Prefecture. As a result, onion shipments are severely affected by meteorological disasters in the production areas, and the supply of domestic products decreases during the summer season (July-August) when the shipment area switches from Honshu to Hokkaido. In addition, there is a strong demand for domestic onions for commercial processing purposes, for which price stabilization and a strong year-round supply of domestic products are required.
In response to these demands, we have outlined spring-sown onion production in the Tohoku region as a technology that enables domestic shipment of onions in the summer, and advanced the implementation and demonstration at the production sites. In the process of expanding the planting, frequent occurrence of putrefactive diseases and problems in cultivation management in large-scale farming have become evident. Accordingly, in spring-sown onion cultivation in the Tohoku region, with the goal of stable production of 5t/10a yield or higher even in large-scale operations, we arranged operation procedures, drew up fertilization standards, and developed pest control technologies. In addition, we conducted field demonstrations of mechanization systems in paddy conversion fields in cooperation with regional public research institutes to clarify the effects and conditions of the technology introduction, and summarized them as the "Standard operating procedures for spring-sown onion cultivation system in the Tohoku region".

By using this procedural manual to expand onion production in the northeast region, it will be possible to achieve a stable supply of domestic onions.
