Abstract

Shimonita-Negi, one of Gunma Prefecture’s specialty vegetables, is a single non-tillering leek.
The Shimonita region, which is the production area of Shimonita-Negi, is located on the mountainside.
The leaf sheath of Shimonita-Negi is about 5 cm in diameter, considerably thicker than the 2-cm diameter of the general leek in Japan.
The leaf sheath length of Shimonita-Negi is short at approximately 20 cm.
According to previous studies, Shimonita-Negi grew well and was of good quality in the Shimonita region (cool climate) but did not grow well in Maebashi in Gunma Prefecture (hot climate). However, details of growth in each region have not been reported.
Therefore, Shimonita-Negi were cultivated in three regions with different air temperatures in Gunma Prefecture in this study: cool (Shimonita) and hot (Takasaki and Isesaki), and their growth and yield were investigated.
In addition, the effect of earthing up, which is one of the important management tasks in Shimonita-Negi cultivation, was also examined at each test site.
The leaf length and the number of leaves were highest in Takasaki followed by Isesaki and Shimonita.
Shimonita-Negi grown at Takasaki had the most vigorous growth.
Further, the spread of wide leaves, which is a characteristic of Shimonita-Negi, was maintained by earthing-up practices in Shimonita, where the air temperature is the lowest among the test sites.
These results showed that when Shimonita-Negi are cultivated in places with high air temperatures, the leaves and leaf sheaths are longer, and the number of fresh leaves increases compared to Shimonita-Negi grown in relatively low air temperatures.
Our study clarified that Shimonita-Negi growth is influenced by air temperature.
