... presents the laboratory and field evalation results of NEPER Wheat expert system. The laboratory evaluation showed that NEPER performance is comparable with human experts. Field evaluation has revealed that NEPER has good economic and environmental impacts. The field testing results have also shown that NEPER is usable, applicable and needed.

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 ...
