This study conducted experiments on the reclaimed land of Saemangeum located in Jeongrabuk-do in order to gain basic information about growth characteristics and yield ability according to soil salinity. Having soil excluding salt as a control group, this study adjusted the specimens' soil salinity to level 4 and then planted four varieties including Ilmichal Corn to investigate the growth or grain yield according to salinity. About the corn establishment rate according to soil salinity, over

According to the salt concentration of soil more required growth duration from seeding to heading comparing to non-treatment salt was delayed, at 1.6 dS m -1 ISSN 0252-9777(Print) ISSN 2287-8432(Online)
