Abstract
The aim of this study was to test a utilization possibility of hairy vetch as a green manure in rice cultivation. The effect of hairy vetch on yield and nitrogen uptake or rice was investigated for three years. The yield of rice increased by 7% when hairy vetch was supplied at 2~3 weeks before rice transplanting compared to that of 1 week. The proper amount of hairy vetch incorporated into soil without nitrogen fertilization was . There was a severe lodging of rice with yield reduction when hairy vetch was supplied over . When of hairy vetch was supplied the rice yield increased by 6% due to the increase of panicle number per square meter 20%.
