The aimed of research was to make a comparison of the economic efficiency of wheat crop producers in the desert areas of Karbala governorate for adopters of pivot irrigation technology and those who do not adopt by measuring the economic efficiency and its components (technical and allocative) using data envelopment analysis (DEA). Through the quantities and prices of resources and estimation of the surplus and deficit quantities of the resources used to actually produce the wheat crop and the quantities achieved for efficiency and by focusing on the irrigation water resource and based on field data for a random sample. The sample size for wheat producers in the pivot irrigation system was (100) farmers out of (571) farmers in Ain Al-Tamr district according to the agricultural plan of the Karbala Agriculture directorate with a sample of wheat crop producers in the tourist irrigation system (100) farmers Out of (178) farmers in Al-Hur district according to the agricultural plan of the Karbala agriculture directorate through direct interviews with farmers, By analyzing the data envelopment of the research sample, it was found that the farms under the pivot irrigation system achieved full technical efficiency and the stability of the return to scale by 22% of the total sample, while the farms under the pivot irrigation system achieved a percentage of 0.5% This indicates the importance of the pivot sprinkler irrigation technique in reducing the resources used to achieve complete technical efficiency, and the most important of these resources is the irrigation water resource. The average allocative efficiency was (0.82) and economic efficiency (0.72) in the center pivot irrigation system, Due to the good exploitation of the resources used in production, these farms can become more efficient if the support of modern technologies in agricultural production is increased, which reduces production costs and raises the level of allocative and economic efficiency, By estimating the size of the economic resources and the amount of surplus or deficit of resources to produce the wheat crop for the research sample, It was found that there are surplus quantities of productive resources used in the production of the wheat crop (cultivated areas, seeds, dab fertilizer, urea fertilizer, pesticides, irrigation water, mechanized work) under the tourist irrigation system compared to the farms operating under the pivot irrigation system.
