다국어 초록 (Multilingual Abstract)

This experiment was conducted to investigate the effects of nitrogen fertilizer application before transplanting rice on the height, dry matter yield, green yield and dry matter ratio in Italian rye grass at Department of Daily Science, Jinju Agricultural ＆ Forestry Junior Technical College from Feb., 1982 to July. the same year.
The results obtained are as follows:
1. The higher nitrogen fertilizer application level was, the more the height, dry matter yield and green yield was largely superior, but the dry matter ratio was superior when it was low. The effects of it was highly significant(P<.001) differences for the traits studied.
2. The height, dry matter yield and green yield in the second cutting stage was superior but the dry matter ratio was superior in the third cutting stage.
3. The height, dry matter yield and green yield was superior in the N-50kg×the second cutting stage and the dry matter ratio in the N-15kg×the third cutting stage.
The above mentioned results suggest that the height, dry matter yield and green yield be superior in the N-high groups and the second cutting stage and the dry matter ratio in the N-low groups and the third cutting stage.
