OPTIMIZATION OF WATER USE IN AGRICULTURE Tubas Area is a Case Study
A linear programming model was used to optimize the vegetables farming based in Tubas area. The analysis was applied to eight vegetable crops (e.g. Tomatoes, Eggplants, Potatoes, Cucumbers, Peppers, Cauliflowers, Onions, and Squashes).
The objective function of the model is to maximize profit. Profit is defined as the difference between revenue on one side and production and water costs on the other side. There are three major constrains judging the objective function. The first constrain relates to the availability of land for agricultural use. The second constrain defines the total amount of water allocated for a district. The third one relates to the crop production, different marketing potentials and food security requirements. Combining these three constrains, an objective function equation has been developed to maximize profits for zones j, from crops i, using one of the irrigation systems.
Several additional constrains may be introduced to enrich the model and to account for realistic restrictions in the system such as type of soil and proper planting season. The linear optimization model solved using a computer Software to Find crop pattern area in dunums (Xij).
It is concluded that Peppers in zone 2 and Cauliflower in zone 1 have the maximum water profit. In addition, Cucumbers and Eggplants have the largest areas planted in both zones.
