A field experiment was performed to evaluate corn yield and water use efficiency in relation to the salt concentration level of irrigation water with a trickle system in the Mediterranean Region of Turkey. Saline irrigation water with EC of 3.0, 6.0, 9.0, and 12.0 dS/m along with canal water of 0.5 dS/m was used. Three treatments were included by applying 10 percent leaching fraction to 0.5, 6.0, and 12.0 dS/m treatments after flowering. Results indicated no significant difference in corn grain yields among the treatments as indicated by the variance analysis from the treatment plots irrigated with canal water. Applying 10 percent leaching after flowering didn't affect the salt-distribution profile significantly. There were no significant differences in dry matter production levels, water use efficiency (WUE), 1000-grain weight, and harvest index (Hl) among the salinity treatments. Saline irrigation water may be used for irrigating corn with trickle system under the Mediterranean climatic conditions.
