The role of investment in developing the agricultural sector in Iraq for the period (1989-2019) Investment is considered one of the main tools that achieve economic development and determines the growth path in the development countries. It is considered the future determinant of expansion in production capacity, and the main research problem was to know the main problem of investment. The agricultural sector in Iraq and the importance of research lies in the importance of the agricultural sector to the Iraqi economy, due to the role of the agricultural sector in revitalizing economic life to motivate producers to increase production. The aim of the research is to identify the role of the agricultural sector in Iraq in terms of quality and follow-up developments in the volume of investments and to know the extent of its contribution to the national product in Iraq. Where it was relied on a time series of beqat for the period (1989-2019), which are (agricultural workforce, average per capita GDP, agricultural fixed capital accumulation, total agricultural product, investment allocations, interest rate, chemical technology in Iraq) independent variables and (Total agricultural investments) is a dependent variable, and the stability of the time series was chosen. From the results of the tests, it was clear that only two variables stabilized at the level and the rest of the variables settled at the first difference. The ARDL model was applied, and joint integration was chosen. It was found that there is a long-term equilibrium relationship, and we note that the short-term parameter The independent variable (X1) amounted to (0.123), which means that there is a direct positive relationship between the dependent variable (agricultural investments) and the independent variable (the agricultural labor force), and the variable (x2) amounted to (2.325), which is a positive and direct relationship, and the variable (83) amounted to (-0.297), and this means that there is an inverse relationship, as well as the variable (X4) amounted to (1.082), which means the relationship is soft and wavey, and that the variable (85) has a value of (0.420), meaning that the relationship is direct and meal, With regard to the variable (6), its value reached (-6.680), which means that the relationship is inverse and conforms to the economic logic, and finally the variable (X7) has reached (0.690), meaning that the relationship between them is direct and moral.
