Abstract EN

The study showed that there was a difference in the area of the cultivated area of the crop in the district Of shameya for the period amounted to the cultivated area in 1997 (107192) dunums this area decreased to(39240) dunums in 2015 .

the reason for this decline was due to the variation in the volume of water flow of the Euphrates river during the study period ,as well as the increase in production cost for the crop from (42000) dinars in 1997 to (608175) dinars in 2015.
