Quantitative Estimation of Corn Production Function In Iraq of (1986 – 2003 ) duration
Abstract
The objective of the research is to estimate the production of corn by using power and linear functions for one depended variable, choosing the double log model and linear model , then testing them by first and second statistical tests , they must be suitable for agricultural production economic theory . The development of corn productivity in Iraq in the ( 1986 – 2003 ) duration was 2310 kg/ha ., while were 900.4 and 1600 kg/ha in (1950 – 1967 ) and ( 1968 – 1985 ) durations respectively . Thus their was vertical expansions. There was horizontal expansions of corn production too. The economic derivatives were estimated , they represent the marginal production and the average production functions , and production elasticities . The main result was the noneconomic first stage of the law of diminishing returns represented corn production in Iraq . The productivity was low when it compared with the productivity of developed countries. Thus , the important suggestion is to do our best on reaching to higher production level.
