Abstract
Dry onion harvest of crops mission in Iraq in terms of economic activity and consumption on every Iraqi house and contains important minerals and the percentage of metals in the edible portion of it containing 0.32 calcium and potassium, 0.183 and 0.068 and 0.044 and 0.015 and 0.015 and 0 .00005 sulfur, phosphorus, sodium and Magnesium, sequentially, the aims of study to assess the function of the total demand for dry onion crop and learn the most important factors affecting the demand for it by using the method of least squares for the period 9019-2007 have been used economic and statistical criteria in assessing the efficiency of the model has included the model variables (Consumer price onion, national income, population, and time) has been conducting three attempts, the estimated models were significant at 1%, according to statistical criteria, but signs of the estimated parameters some of which are consistent with the logic of economic theory and the other is consistent with the logic of economic theory as well as in terms of some statistical parameters of the moral and the other is moral, and was the third attempt is the best and as logarithmic double where the value of R ² = 0.61 or 61% of the factors that affect the demand for onions contained in the function, and elasticity's of demand price was 0.42 meaning that demand for the commodity is inelastic the fact that the modulus of elasticity less than one, and the commodity its very necessary for Iraqi consumers .
