| Outline of Final Research Achievements |
Development of cultivation was conducted by the introduction of plowing hairy vetch and timing of higher top nitrogen dressing of job’s tears.
Dry matter weight of hairy vetch decreased with being late at timing of plowing. The 20 to 50% of nitrogen absorbed by job’s tears at heading stage was from hairy vetch, that suggest that plowed hairy vetch contributes to vigorous growth of job’s tears during vegetative stage. Grain yield of job’s tears in plowing hairy vetch at 7 days before sowing was higher than that at 30 days, and was same level as that in chemical fertilizer. Furthermore, grain yield was the highest in higher top dressed at tillering stage.
