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 are 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.
