  This research was conducted as split plot experiment based on randomized complete block design in three replication at research farm of Islamic Azad university of Ahvaz branch to determine water requirement and optimum planting pattern of corn hybrid (S.C 704) in 2012. Main plot was irrigation included three level (60%, 80%, 100%) and sub plot was included two planting pattern (cultivate in furrow and middle of stack). Effect of water requirement on all measured traits (soil salinity, soil moisture percent, sodium absorption rate, day to flowering, days to silk appearance 50%, number of rows per ear, number of grain per row, grain weight, grain yield, yield dry matter) expect harvest index were significant at 1% probability level. Interaction effect of water requirement and planting pattern on traits of soil salinity, soil moisture percent, sodium absorption rate, grain yield and dry matter yield were significant. Treatment of 100% water irrigation and planting at furrow had Maximum grain yield (1086.2 g.m-2) and yield dry matter (2060.5 g.m-2). Maximum soil salinity (6.183 ds.m-1) and sodium abortion rate (4.487) were achieved at treatment of 60% Irrigation and planting on middle of stack. Generally it can be recommended to planting furrow without drought stress and supply water requirement completely to achieve maximum corn yield in Khuzestan sour lip land. Manuscript profile
