Abstract
The study tackles the effect of agricultural investment in developing the agricultural sector in iraq for the period 1880-2000.analysis has been made by the minimum square method in two stages (2.s.l.s). Linear function has been chosen as the best means for the equation in accordance with economic aspects representing the correlation between agricultural investment being a variance and the limited factors being independent variances. They are agricultural loons to form the fixed agricultural capital, G. D. P., trade balance, chemical technology, mechanical technology, agricultural work force, agricultural domestic product. It is clear from analysis the significance of all variances (forming fixed capital, trade balance, mechanical technology, agricultural domestic product).as for the second stage of estimation, values of agricultural investment have been used being a variance and the agricultural growth being a variance dependent upon the decided function. There is also a negative correlation between the agricultural product growth and the agricultural investment. This correlation shows the negative reflections of both war and blockade as well as concentrating investment expenditure upon projects of infrastructure and reconstruction neglecting protects of agricultural product, all this has led to the weakness of agricultural investment and in consequence the weakness of the agricultural product growth.
