The most important objective of quantitative economic studies is to predict in economic variables values in order to plan for production and import policies in Iraq . Many techniques could be used to predict economic variables . In this study ARIMA model was used This model is a mixture of autoregressive technique and moving average for time series data in order to predict in wheat supply for Iraq . This model is also characterized by high accuracy in analyzing time series data . Time series data for wheat acreage was used for the period (1961-2007) . The suitable model was identified and it was ARIMA (2,1,0) model . This model predicted the wheat acreage until 2015 , and it satisfied all statistical and predictive power tests.
