THE ESTIMATION OF THE EFFECT OF AGRICULTURAL AREA FUNCTION ON SESAME PRODUCTION IN IRAQ THROUGH THE PERIOD (1986 – 2010 )

Abstract

Abstract The objective of present study is to estimate the effect of agricultural area function on Sesame production in Iraq through the period (1986 – 2010 ) by using power function for one independent variable, choosing the double log model , it must be suitable for agricultural production economic theory according to the important hypothesis stated that there is a positive relationship between the agricultural area and Sesame production.The function passed the first , second statistical tests and Chow test . The economic derivatives of production function were estimated , they represent the marginal production and the average production functions , and production elasticities . The main conclusion was the first stage of production of the law of diminishing returns represented the Sesame production in Iraq . The productivity was low when it compared with the productivity of the wor1d countries ,for example Egypt . Thus , the important suggestion is to do our best on reaching to higher production level by using the intensive ,or the extensive agriculture, or both .
