Watermelon is a plant crop rich in water, which constitutes 92% of its content, making it ideal for hydrating the body in the summer. It also contains many vitamins and minerals. It is grown in more than 100 countries. Watermelon is not just a fruit; it is an integral part of Iraqi food culture and a symbol of special occasions and the summer table. The study aimed to identify the optimal resource combinations used by watermelon farmers in Rabia District for the 2024 agricultural season. The Cobb-Douglas production function was calculated to determine the optimal quantities of resources that maximize profit and minimize cost, and compared to the actual situation. Multiple resource combinations and different production levels were also calculated using isoquant curves, using data collected by a questionnaire for (34) farms, representing 25% of the study population, with an average area of (6) dunums. One of the most prominent results is that the optimal production reached (37,762) kg. The farmers' profits were (5,704,102) dinars. When compared to the actual farmers' production of (29,040) kg, the profits amounted to (2,869,452) dinars. Meanwhile, Profits, including cost reductions, amounted to (4,224,380) dinars. Based on the presented results, the study recommends that watermelon farmers be guided by optimal supply quantities, whether those that maximize profit or minimize cost, to maximize their profits.
