| Abstract | ||
| In this research study in response view acreage planted with lentils in Iraq for a period (1993-2013) by applying the model Nerlove and koyck , By adopting lentil acreage as the Dependent variable , the in dependent factors are domestic price of the crop and the space to the age of its predcess or and productivity earlier Age and risk price and productivity risk and so for years for a period of Time series (1993-2013) , It was apply the formula of linear and logarithmic formula half ogartmih formula half ogartmih patterns , the Best choice to represent the relationships function careless in terms favorable than in terms ,Analysis was divided into two periods, The first for period (1993-2003) and second for period (2004-2013), it was clear from the results of statistical analysis that accented domestic price of lentils do not agree with the economic logic suggests not to increase farmers response price , It turned out that The area of the prior year amounted to (3.753005) have a significant effect , the productivity variable to prior year was worth (0.012) and its impact was not significant , the stunt- price coefficient was positive and not significant at the required level and the lack of its ,variable influence has been positive and the value of the parameter (0.104) and this means that the effect of the risk for productivity does not constitute an important figure in the agricultural policy specialists in the culture lentil crop, the coefficient of determination (R2) reaching up to (0.56) Also make sure not amoral model as a whole through the test (F) ,Also make sure our Lack of self- correlation problem through values (D.W) , It was calculated Elasticity and price reaches (1.20 ) ,The results of the analysis of the second period for the period of(2004-2013) was All parameters signals without the approval of economic logic and not significant, Reached the coefficient of determination (R2) %0.50 , And it proved be amoral model as whole through the test (F) , And show us free model of autocorrelation problems through testing (D.W) , the model koyck lost in This model is that the total production of the worker either independent Factors are the total area and production of the prior year , It was applied Function to study the relationships of the deltoid lentil , It was clear from There result of statistical analysis , the variable space was positive and Significant at the required level , the out put of the year and is appositive Moral predecessor , It was clear from the coefficient of determination (R2) robust state security was (0.93)to %93of the change the occur in the Model tibbh factors , And it proved significantly the function as whole through the test (F) , It was calculated weights Alambtaeh clear from the analysis that the weights are decreasing gradually . | ||
