The farm income of the region has been supported by cultural systems based on winter cereals.

The present work intends to evaluate the viability of investments in irrigation equipment's for several capital and water costs combinations. In order to achieve the stated objective a multi-period linear programming model was built where, besides the investment possibilities, the CAP reform measures were included.
