Abstract

Irrigation with saline water needs to the different managements to reduce the harmful effects of salinity on plants, soil and the environment. simulation models are the useful tool to irrigation management in conditions of soil and water salinity because, they can predict crop Yield and soil conditions considering to different climate, plant and management practices. In this study, the SALTMED model was evaluated under different conditions of irrigation management with saline water for corn. Irrigation was done with tape irrigation system in the strategies mixing, one-alternate and half-alternate of fresh water and saline water at four levels of salinity. The SALTMED model was calibrated based on half of the treatments and validated with the other half. The model calibration was done on Soil moisture, Yield and biomass. The average of normalize root mean square error (NRMSE) for simulation of Yield and biomass calculated 3. 21 and 2. 35 percentage respectively, that indicating high accuracy for model. The mean of NRMSE in simulation of Soil moisture for different managements calculated 6. 52 percentages. As well as the SALTMED model simulated distribution of soil salinity in alternative strategies with less accuracy (NRMSE=15. 71) than mixing management (NRMSE=9. 57).
