A field experiment was carried out in one of the fields of a mixture of soil in College of Agriculture and Marshes, Dhi Qar University, to study the effect of six treatments of irrigation level and the addition of agricultural gypsum to the soil, namely: T1: Irrigation level 50% without adding gypsum, T2: Irrigation level 50% with the addition of gypsum, T3: Irrigation level 75% without adding gypsum, T4: Irrigation level 75% with the addition of gypsum, T5: Irrigation level 100% without adding gypsum and T6: Irrigation level 100% with the addition of gypsum. By adding gypsum to some soil properties, growth and yield of sorghum, water productivity and water use efficiency, according to a Completely randomized design (CBD) and with three replications. The results showed that there were significant differences between the treatments for all the studied traits. The treatment gave the irrigation level 100% with the addition of gypsum, the highest significant values for all studied traits. The treatments to which gypsum was added also outperformed compared to treatment without addition, as well as irrigation at a level of 100% with the addition of gypsum to improve soil properties, reduce the effect of salinity, increase growth and yield characteristics of sorghum, increase water productivity and water use efficiency.
