The Total Costs of Wheat and Watermelon Crops Grown in Diyala Governorate / Al-Adhim Region, a Model for the Year 2022

Abstract The research reviews the marginal product function, indicating also the factors influencing the choice of irrigation sources, and the efficiency relevant to this research. In order to analyze the indicators of both technical efficiency and economic efficiency of the methods of using the studied irrigation water sources, it is necessary to analyze the total production costs and the various measures related to the economic performance of the wheat and parchment crops. The average total costs of producing one Acres of watermelon for farmers who used Al-adhim Dam water using the superficial method amounted to about 1,737,199 dinars per Acres. As for the total production costs for the Acres planted with watermelon and irrigated with groundwater for both the surface watermelon and drip irrigation methods, the average amounted to approximately 1,928,312 dinars. /Acres, and 2,269,835 dinars/Acres, respectively. It is noted that the total output of the subterranean farmers who irrigated their crops with groundwater using the surface irrigation method amounted to 2,649,468.75 dinars/Acres, while the output of their counterparts who relied on the drip irrigation method recorded 2,981,745.13 dinars/Acres, while the economic efficiency was recorded The profitability of production is 0.37, which means that irrigating the watermelon crop with the water of the Al-Adhim Dam on a superficial basis achieved profits, and that every single unit of the total production costs per Acres gave a net income at a rate of 0.37 dinars/Acres for the watermelon crop. As for the wheat crop, the total output of the crop that was irrigated with the water of the Al-Adhim Dam With the surface irrigation method, it amounted to 546,923.73 dinars/Acres, while the output for its counterpart that was irrigated with the pivot irrigation method was 591,011.9 dinars/Acres. When the wheat crop was irrigated with groundwater using the surface irrigation method and the pivot irrigation method, the total output reached 585,976.56 dinars/Acres, and 618,444.44 dinars/Acres, respectively. The total yield of the wheat crop, which was irrigated with water from the Al-adhim Dam using the surface irrigation method, amounted to 546,923.73 dinars/Acres, while the yield of its counterpart, which was irrigated using the center-pivot irrigation method, recorded 591,011.9 dinars/Acres. There were also no significant differences between the two results, as the significance value was 0.95, noting that there were also no significant differences recorded between the productivity of a Acres of wheat grains irrigated with water from the Al-adhim Dam using the surface irrigation method (769.3 kg/Acres), and its counterpart irrigated using the center pivot irrigation method (791.18). kg/acre).
