Production Function of Irrigated Wheat Crop With Spray in Salahuddin Government , for The Production Season 2016 -2015 Al Alam City - Applied Model .

Abstract

The wheat crop of the most important strategic food crops in the world and come this strategic importance of wheat from being a staple food per capita in most regions of the world as well as its importance for Iraq. Of the basic problems faced by the wheat crop in Iraq in general and in terms of science in particular is the increase in production resulting from the use of farm resources costs amounts stray too far from the ideal use them, derived from the low level of performance of farm management. Used a cup function - Douglas Y = A Lb1 Kb2 Nb3 wheat crop irrigated sprinkler in hand knowledge of a sample of 60 irrigation system, as it has been divided into three categories, the first category is made up of 20 with donm of 120 donm system, the second category is made up of 20 with an donm of 80 donm system, the third category is made up of 20 with an donm of 60 donm system, and found that the optimal size of the production of the systems category (120.80, 60) has reached (1504.3742 , 1245.286 , 1170.584) kg / donm respectively, regarding farm optimal size was (103.0572, 67.0706, 51.67) donm respectively, while the optimum amounts of work item was (19.2, 15.43, 21.20), respectively, and the capital investigator for the optimal size of production and civil costs have reached (159.255322, 141.0469811, 149.8279094) thousand dinars respectively, while net profits reached (881,616.52055, 732,066.04373, 654,663.1193) dinars respectively, have occupied the systems category 120 donm the first place to achieve a higher net profit . Were taken from a time series of production space and productivity at the country level and the province of Salah al-Din, for the period (2013 - 1985) was the equations of general trend account, as well as calculate the annual growth of its rates, as results showed that the annual growth rates are positive in terms of production and productivity space at the country level as she was (0.049, 0.012, 0.037) , respectively, while for the province of Salah al-Din annual growth of production and productivity rates were positive as she was (0.029, 0.047), while the annual growth rate was negative space as it was (0.018-) . It shows that the overall flexibility of the production has reached (0.975, 0.990, 0.898) for the systems (120.80,. 60), respectively, and this confirms the fact that production in the second phase (economic stage) . It is the outcome of the economic analysis of economic derivatives of each of the average production and the marginal product of productivity and flexibility were in accordance with the economic logic as derivatives showed that the average value of production is greater than the value of the marginal product of the levels of production with in the study, the production flexibility has given results values are the same as the value of the flexibility of variable production element.
