The study was carried out in the areas of irrigated crops and vegetables that depend on wells for irrigation (no less than three years) during 2019-2020 seasons, in Swaida governorate, with the aim of studying the efficiency of the management of irrigation wells, the financial evaluation of their farms, the farmers' attitudes towards the production problems, and achieving several scenarios of optimal cropping patterns. This was done based on a questionnaire targeting 106 farmers, and it relied on several methodologies in economic analysis: descriptive, quantitative, financial, developmental, in addition to quantitative analysis in management through the use of operations research models, single and goal linear mathematical programming. A Quantitative analysis in management suggesting four scenarios for the optimal cropping patterns according to the linear programming models: Scenario 1: Reallocated to each crop to achieve the highest return as it increased by 80.8% over the net return of the actual pattern4 Scenario 2: An increase in the actual cultivated area was proposed by 21.14%, and as a result, the total net return of the second alternative would increase by 111.75% than the actual pattern4 Scenario 3: Achieving a saving in the total amount of irrigation water for the proposed pattern by 44.86% comparing of actual pattern4 Scenario 4: It achieved an increase in the total net return per irrigation water unit about 13.26% over the actual formulation. According to the results of the goal linear programming models, which included three goals together: (maximizing the return of the unit area, maximizing the return of the unit of water, and minimizing the consumption of irrigation water). The first Scenario: it achieved the two goals: maximize the returns per area and water unitwithout deviations, while it achieved the goal of minimizing the irrigation water with a minimum deviation of 464761.7 m3 with an increase that did not exceed 8.99% over the target. The second Scenario: The cropping pattern achieved the two goals: maximizing the return of the area 10% over the actual, and the same amount of water consumed in the actual pattern without deviations, while it achieved the goal of maximizing the return per water unit with the minimum deviation of 1.55 million SP and do no more than 7.7% over the target. The study recommended the necessity of modifying the cropping patterns in Swaida governorate to achieve the optimum crop pattern that achieves maximizing the net return per area unit and reducing irrigation water, maximizing the return per the irrigation water unit, and the importance of the intervention of the concerned authorities in preparing agricultural plans for irrigated crop patterns based on correct scientific methodologies away from randomness and experimentation in order to achieve self-sufficiency, preserve available resources, and sustain natural resources that are scarce
