A computerized model with (Microsoft QuickBasic version 1.1) was proposed for simulating the effect of deficit irrigation for maize crop during spring and autumn seasons in Mosul region. The simulation is based on 16 years of climatological data for the period ( 1985-2000 ) for Mosul meteorological station , which includes daily maximum and minimum temperatures , maximum and minimum relative humidity , wind speed at 2m height , and sunshine hours , which is used to calculate daily reference evapotranspiration with Penman-Monteith equation .The model predicts yield reduction by changing irrigation depth for three different irrigation methods (sprinkler , furrow and drip) .The rainfall is divided into three classes which represent three regions (wet ,semiarid and arid ). 9 / 3 / 2004 2 / 12 / 2004 Al_Rafidain engineering Vol.13 No.1 2005
