NEPER: a multiple strategy wheat expert system

This paper presents a methodology for developing a strategic Expert System for wheat crop production, which has been developed using a Multiple Design approach. This Expert System consists of six subsystems; namely, variety selection, land preparation, sowing, irrigation, fertilization, and harvest. These subsystems exchange data between them through a common database. Each subsystem advises wheat growers on the corresponding plan(s), comprising a set of agricultural/chemical operations before or during the growing season. Applying an appropriate plan reduces risk to farmers from having a problem during the growing season. The system was verified, validated, and, tested in the field. Beneficial economic and environmental impacts have been demonstrated.
