Abstract

The production function of Tomato was studied in the open cultivation irrigated with surface irrigation in Diyala governorate in 2018 through a questionnaire of (45) random sample selected from (244) farms out of the total population of the study. The sample area was (185.4) dunem (2500 m2). The analysis was done by taking the natural logarithm of the production as a dependent factor and for each resource of production as an independent factor. The half- logarithmic model was chosen as the best model. It is clear from the analysis that some of these resources have been exploited optimally through the positive singles to the resource parameters in the function. This means that the production of these resources was in the second stage of the law of decreasing yields. (The number of labor hours per day, the amount of animal manure used and the number of irrigations during the season). The quantity of chemical fertilizer was found to be a negative impact on production because the elasticity signal was negative. And the regression analysis was achieved by taking the natural logarithm of both the labor and the capital in order to achieve the overall elasticity of the production using the Cobb-Duglas model. It became clear that the elastic ties of these resources were positive and this means that the combined production resources achieve high productivity due to their cooperation this resource and the efficiency of the mixing process. What can from the exploitation of additional units in the desire to expand production, and was recommended to follow the agricultural guidelines and the adoption of the results of scientific research in the use of resources, especially the amounts of fertilizer and farm management in order to continue these projects to achieve self-sufficiency of Tomato.

Abstract

The study examined the production function of a random sample of date palm farms in Diyala Governorate. The sample included (53) farms with (8374) fruitful palm trees from the study population of (22943) palm trees. The multiple regression of the elements of the function was analyzed. This included labor costs, fertilizer costs, pesticide costs, The analysis showed that the effect of fertilizer costs, pesticide costs and labor costs on the quantity of production was positive ,The number of irrigation during the year had a negative effect on the quantity of production where its elasticity was negative, the study showed that weak government support, high production input prices, neglect of control programs, lack of awareness of palm tree service operations, soil service and the spread of poor varieties are among the main reasons for the decline in production, the decline of new palm trees, the increase in labor wages, the low labor experience, the low price of local dates and the competition of imported dates ,The reasons for the decline in production were , and it was recommended that government support for palm farms and programs to fertilize and control date palms and provide good varieties of production, especially support for textile agriculture, which provides excellent varieties and with good productivity.

تناول البحث دراسة دالة الانتاج لعينة عشوائية من مزارع نخيل التمر في محافظة ديالى شملت العينة (53) مزرعة بواقع (8374) شجرة نخيل مثمرة من مجتمع الدراسة البالغ (22943) نخلة, وتم تحليل الانحدار المتعدد لعناصر الدالة وشملت تكاليف العمالة وتكاليف الاسمدة وتكاليف المبيدات الحشرية وعدد الريات خلال السنة واتضح من خلال التحليل ان تأثير كل من تكاليف الاسمدة وتكاليف المبيدات الحشرية وتكاليف العمالة على كمية الانتاج كان ايجابياً اما عدد الريات خلال السنة كان تأثيره سلبي على كمية الانتاج حيث كانت مرونته سالبة ,وبينت الدراسة ان ضعف الدعم الحكومي وارتفاع اسعار المدخلات الانتاجية واهمال برامج المكافحة وعدم التوعية بعمليات خدمة اشجار النخيل وخدمة التربة وانتشار اصناف رديئة من اهم اسباب تردي الانتاج وتراجع زراعة اشجار جديدة من فسائل النخيل وارتفاع اجور العمل وضعف خبرة اليد العاملة وانخفاض سعر التمور المحلية ومنافسة التمور المستوردة لها كانت من اسباب تراجع الانتاج ,وتمت التوصية بضرورة الدعم الحكومي لمزارع النخيل واعداد برامج لتسميد ومكافحة اشجار النخيل وتوفير اصناف جيدة الانتاج لا سيما دعم الزراعة النسيجية التي توفر اصناف ممتازة وذات انتاجية جيدة.

Abstract

The wheat crop of the most important strategic food grain crops as it's source of food for more than (35%) of the world's population, particularly in third world countries from which Iraq.. This study deals with the subject of measuring the economic efficiency of rain-fed farms wheat in the region in order to identify the most important factors affecting the level of efficiency, in addition to estimating the size of the resources generated economic efficiency overall. It was obtained preliminary data from field sources by relying on a stratified random sample of wheat farmers included (225) farm productive season (2013-2014) in the province of Sulaymaniyah. It has been measuring the Total economical efficiency in accordance to the cost function parameters . It was found that the average of the price efficiency for each of the five categories was 74%, 60%, 58%, 63%, and 68% respectively giving a general average of 64%. In addition to that the measured economical efficiency of the five categories of the wheat cultivated farms 60%, 42%, 35%, 30%, and 47% respectively with an average of 44%. The size of the resources achieving the economical efficiency has been calculated and when subjected to comparison, it appears that there is a surplus in all the resources used.

تتناول هذه الدراسة موضوع قياس الكفاءة الاقتصادية لمزارع القمح في المنطقة الديمية من اجل الوقوف على اهم العوامل المؤثرة على مستوى الكفاءة, فضلا عن تقدير حجم الموارد المحققة للكفاءة الاقتصادية الكلية. و تم الحصول على البيانات الاولية من مصادرها الميدانية من خلال الاعتماد على عينة عشوائية طبقية لمزارعي القمح ضمت (225) مزرعة للموسم الإنتاجي (2013- 2014) في محافظة السليمانية. إذ جرى قياس الكفاءة الاقتصادية بمكوناتها الفنية والسعرية على وفق متغيرات دالة التكاليف فضلا عن تقدير حجم الموارد المحققة للكفاءة الاقتصادية، ومن خلال تقدير الكفاءة الاقتصادية الكلية ومكوناتها على وفق متغيرات دالة التكاليف, اتضح ان متوسط الكفاءة السعرية للفئات الخمس قد بلغ (74%,60%,58%,63%,68%( على التوالي محققة متوسطاً عاماً بلغ (64%). فضلا عن ذلك ,فقد بلغ متوسط الكفاءة الاقتصادية للفئات الخمس من المساحات المحصودة لمزارع القمح (60%,42%,35%,30%,47%( على التوالي, مسجلة متوسطاً عاماً بلغ مقداره (44%) لأجمالي مزارع القمح في العينة المدروسة. هذا وقد تم تحديد حجم الموارد المحققة للكفاءة الاقتصادية و التي اتضح من خلالها وجود فائض في جميع الموارد المستخدمة.
