Drainage water and its accumulation due to sugarcane cultivation and fish ponds in southern Khuzestan province is a serious problem. In order to use this drain, various plants resistant to salinity can be cultivated. In order to achieve this aim, a pilot plot was conducted in a split plot design with randomized complete block design for the cultivation of cotton plant in Mirza Kochan Sugar Research and Cultivation Research Plant. Irrigation was used for drainage, Karun River and intermittentperiodic irrigation (Karun and drainage water as a one-time). The results showed that there was a significant difference between cotton yield in Karun water and Karun and drainage intermittentperiodic irrigation. Yield of cotton with drainage was lower than water of Karun river and irrigation of one in between (drainage and Karun) by 41.7% and 29.4%, respectively. The highest mean yield was obtained in drainage treatment, 1432 kg / ha and for the first sowing date.
