Iraq witnesses a deficit in the production of agriculture products compared to its domestic needs. This is due to the low contribution of agricultural products in agricultural output, due to a number of obstacles, including water resources, soil quality, economic factors, lag in the methods of agricultural production and social problem in rural areas of Iraq. The study was based on a hypothesis that the decline in the quantities of agricultural production in Iraq led to a low rate of contribution of agricultural products in agricultural output during the period 1990-2016. In order to prove the hypothesis of the research, the agricultural output was divided into four categories, plant products, animal products, forest resources and fish wealth .It was based on time series data in calculating the contribution ratios for each category in agricultural output. A number of results have been reached, including a decrease in the contribution ratio of agricultural products in agriculture output during the study period, which we conclude that the agricultural sector did not receive sufficient attention by specialist in it as well as the stumble policy in agricultural production therefore, we recommend increasing the value of investment allocations in the fields of agricultural infrastructure and attracting foreign investment companies directly to invest their funds and expertise in Iraqi agriculture and the implementation of policies and procedures of tax protection of the local agriculture products and the development and training of agricultural workforces on the methods of modern production
