| Abstract | ||
| Is the rice of summer grain crops characterized by high food and consumer importance to most citizens in Iraq , In the study estimates supply function for rice in Iraq for the period (1990 -2013) ,The research study also winning development in the acreage production and average per capita consumption and consumer price ,As well as the study of most important factors affecting the supply of rice crops , As it promised to the quantity supplied (Y) as continued , The independent factors are the cultivated area, The purchase price for the previous year for the rice crop ,the price of urea fertilizer, and water levels on the level of Iraq, time and so time series for the period (1990-2013),It was application of linear semi-Logarithmic, Logarithmic Inverse and double-Logarithmic models, the best choice to represent the function studied the relationship based on preferences in terms of statistical test and standard function to choose semi-Logarithmic function as the best function of rice crop and water levels lead to increased production, The increase in urea, it leads to decline in the supplied, It also concluded that the food gap during the period of study was the lowest level reached (-0.33) tons in 1991 and reached its peak(-1417.519) tons in 2011, And that the self-sufficiency ratio was high reached (130.740) in 1997 by the Us occupation in 2003 and then decreased rate of (3.03) where Baggett in 2003, The study recommends the establishment of the Ministry of Agriculture of different formations and ministries of irrigation electricity and oil . And to provide the elements of production of rice crop seeds, fertilizer and fuel and the share of water to reduce the cost of production, thus increasing domestic production ,and confirmation of the Ministry of Agriculture expand the production of rice crop in order to reduce the food gap of the crop. | ||
