This study was conducted to identify the effective drainage-time influencing rice yield and grain quality on a reclaimed saline soil, the experiment conducted at the Gyehwado substation of the Honam Agricultural Research Institute from 2002 to 2003. The experimental field contained 0.1 % and 0.3~0.4% NaCl in soil solution, respectively. The experiment involved salinity levels as main plot and sub-plot where consisted of 6 treatments in a split plot design with three replicates. Rice yield performance showed a maximum at drainage-time for 35 days after flowering under medium salinity level, but indicated only 64% of yield level compare to low soil salinity. Percentage of well-shaped rice was high in low soil salinity indicating there are severe affection for grain quality in medium soil salinity regardless water drainage-time.
