This study was carried out to investigate the proper nitrogen fertilizer level at reclaimed saline land in the southwestern area of Korea from 2002 to 2004. The rice cultivars tested were Samcheonbyeo(Early maturing one), Nampyeongbyeo (Medium maturing one) and Hwaseongbyeo(Mid-late maturing one). The results aye summarized as follows: The more the nitrogen level, the more number of panicle and spikelet per unit area was. But, ripened grain rate and 1000-grain weight were decreased at higher nitrogen level. As higher nitrogen level, head rice rate was decreased and protein content was increased. But, amylose content wasn't differ among the nitrogen fertilizer application levels. As increase nitrogen level in head rice yield increased up to 12 kg/10a, 11 kg/10a, in Samcheonbyeo, Hwaseongbyeo and Nampyeongbyeo, respectively. But there wasn't different more than it. Consequently, considering the yield of head rice, ripened grain rate and rice quality. The proper nitrogen fertilizer application level was 11-12 kg/10a at reclaimed saline land in the southwestern area of Korea. 서남부 간척지에서 고품질 쌀 생산을 위한 생태형별 적정 질소시비량을 구명하고자 2003년과 2004년에 호남농업연구소 계화도출장소 시험포장 문포통(세사양토, 토양 염농도 $0.1\%$)에서 삼천벼, 화성벼, 남평벼를 공시하여 질소시비량에 따른 벼 생육, 수량구성요소, 수량 및 품질 관련형질을 검토한 결과를 요약하면 다음과 같다. 1. 단위면적당 수수와 영화수는 질소시비량이 증가할수록 많았으나 등숙비율이 낮았으며 현미천립중도 가벼웠다. 2. 백미의 완전립비율은 질소시비량이 많을수록 낮아졌고, 단백질 함량은 질소시비량이 증가됨에 따라 다소 높아지는 경향이었으나 아밀로스함량은 질소시비량간에 별 차이가 없었다. 3. 완전미 수량은 삼천벼가 질소 12/10a수준까지, 화성벼와 남평벼는 11/10a 수준까지는 증수되었으나 그 이상의 질소시비량에서는 수량차이가 인정되지 않았다. 4. 따라서 서남부간척지에서 벼 기계이앙재배시 완전미 수량, 등숙비율 및 미질 등을 고려한 10a당 적정 질소시비량은 $11\~12$으로 판단된다.

This study was conducted to estimate the adaptability of some rice varieties for wet flooded direct seeding. Characters such as seedling stand, lodging index and milled rice yield are very important factors in order to get stable yield in direct seeding. These characters were compared among the 17 varieties which belong to early, medium, and mid-late maturity groups. Donganbyeo, Hoanbyeo, and Dongjinbyeo showed over 80 percent of seedling stand. Lodging did not occur in Daesanbyeo, Donganbyeo, Geumnambyeo, Ansanbyeo, Juanbyeo, Anjungbyeo, Hwanambyeo, and Obongbyeo. On the other hand, Geumobyeo, Hwayeongbyeo, Dongjinbyeo, and Nagdongbyeo showed severe lodging. The numbers of panicles and spikelets per in early maturing varieties were lower than those in medium and mid-late maturing varieties. There was no difference among medium and mid-late maturing varieties in the ratio of ripened grain. Milled rice yield was not different in medium or mid-late maturing varieties, whille in early maturing varieties it was different from 0.79 to 0.85MT/ha which was lower than in medium or mid-late maturing varieties. Consequently, Donganbyeo, Daesanbyeo and Hoanbyeo was desirable for wet flooded direct seeding in consideration of seedling stand, lodging and yield.
