Problems associated with irrigation in humid regions include uncertainty of whether irrigation
will be necessary in a given year, and the question of whether crop response will be
sufficient to make the required investment profitable in the long run. A prototype knowledge
based system (KBS) has been developed to determine the economic feasibility of a range of
irrigation systems for site specific conditions. The KBS uses information input by the user to
determine possible irrigation alternatives and provides an economic evaluation of suitable
systems based on domain-specific knowledge about soils, crops, irrigation costs, and agricultural
drought in Virginia. Irrigation systems considered by the KBS include center-pivot,
traveling gun and portable pipe systems. Crops considered are field corn, soybeans, and
Preliminary evaluation showed that the KBS was able to effectively determine if portable
pipe, traveling gun and center pivot irrigation systems were suitable, and provide an economic
evaluation of these systems for site specific situations in Virginia. The KBS developed in this
study provides a basic framework which can be used to build a more comprehensive system
which would address a larger domain, considering additional systems and crops.
