【 摘 要 】

In Tomo Area of Gunma prefecture, paddy rice cultivar Goropikari has been widely cultivated since 1993. This cultivar has a good taste, but, farmers pointed out its weak resistance to diseases and insects, low yielding ability and poor grain quality after its release, and they awaited a replacement cultivar. In the 2000s, we recommended replacing it with a new cultivar “Asahi-no-yume” in Tomo area, but we had little knowledge on the cultivation method of the cultiver. Therefore, we studied the method of fertilizer application for “Asahi-no-yume” planted in early and normal seasons in Tomo area for 3 years from 2000 to 2002. We found that it was possible to cultivate the plants with a high yield and high quality by basal dressing 0.5 kgN/a and top dressing of 0.2 kgN/a about 20 days before heading, in both copping seasons.
