摘要：The climate of Iraq is of the subtropical semi-dry type; however, the country wasrich in water resources until a few decades ago. The climate change, the constructionof many dams on the Tigris and Euphrates Rivers in the neighboring countries,wasting water, and mismanagement caused water shortages. Now, there is a need todecrease consumption, good management of water resources and determining thewater requirements and water footprints of the major crops because agriculture isthe first consumer of water. The FAO CROPWAT 8.0 simulation model, theCLIMWAT 2.0 tool, and the Aqua-Crop model can be used in Iraq to find the cropwater requirements (CWR), irrigation schedules and water footprint (WF) for majorcrops, the Aqua-Crop software can predict the effects of water deficits on cropproductivity or yield to improve irrigation under limited water conditions. All ofthat is to improve the management of water resources to cope with drought. Theobjectives of this proposal study beside the calculating of wheat water footprint areto assess the capability of the AquaCrop model to simulate wheat (Triticumaestivum L.) performance in hot dry conditions under full and deficient waterconditions in south of Iraq, to study the effect of various irrigation scenarios (stagesof crop growth and water depth applied) on wheat yield. The AquaCrop model willbe evaluated with experimental data during the field experiment. The AquaCropmodel can accurately simulate root zone, crop biomass and grain yield soil watercontent, with less than 10 percent standardized root mean square error (RMSE).
