A farmer has 3 farms to grow 3 crops. The farms are 500, 800, and 700 acres, and the water allocation for each farm is 600, 800, and 375 acre-feet, respectively The crops suited for this region include sugar beets, cotton and com. These crops differ primarily in their expected net retum per acre and their consumption of water. The USDA has set a maximum quota for the total acreage that can be devoted to each of these crops. Each crop can be devoted to any of the 3 farms, but at least 50% of each farm must be used. Formulate the problem to maximize the net return Maximum quote Water consumption Net return |(acre) 600 500 250 Go 25 Consider the farm planning problem again. To ensure quality between the three farms, it has been agreed that every farm will plant the same proportion of its available land. How do you add this limitation to the model?
