قياس تأثير أعداد النخيل على معدلات إنتاج التمور باستخدام نماذج البيانات المقطعية Panel Data Models

Abstract

the statistical method (Panel Data Models) employed to measure the relation power between the variables and analyze them, and to show the effect of the explanatory variable (X), which represents the number of Zuhdi type palms, on the dependent variable (Y), which represents the quantity of production of Zuhdi dates. In the Iraqi provinces of the Middle Euphrates (Karbala, Babil, Najaf, and Qadisiya) for the period from (2001-2015). As the two variables were represented graphically to know the trend of the phenomenon and determine its events, and among the most important conclusions that were reached is that the Pooled regression model (PRM) is the best in that it is the most appropriate in representing the relationship between the variable of palm numbers and the variable of productivity of ascetic dates, as well as the presence of an effect The significance of the variable date palm on the increase in the productivity of Zuhdi dates. Whenever the number of palm trees increases by one palm, the amount of production will increase by (0.067). On this basis, a set of recommendations were made to take the necessary care and development of the studied phenomenon, the most prominent of which is the expansion of the study sample (number of sections) to include more than the Iraqi governorates that are famous for palm cultivation, and attention to palm cultivation, especially the Zuhdi variety, because the production of dates contributes significantly to supporting the economy Iraqi.
