With the growing population and high farmer to extension worker ratio, there is a great need for an intuitive knowledge based system, which may suggest suitable solutions to the farmers. Expert system on maize attempts to capture the knowledge of human experts and make it available through computer programme. Maize expert system has four essential components i.e. the knowledge acquisition modul...
