From the review of literature, it is clear that an Expert System integrates the accumulated expertise of various disciplines such as pathology, entomology, crop breeding, salinity management and agricultural meteorology into a framework that best addresses the specific problems and on-site needs of the farmers. Thus to meet the requirements , it is proposed that a rule-based expert system will be developed to evaluate how recent information techniques may be used to provide decisions to farmers and extension workers on diagnosing crop disorder, controlling diseases, pests selecting the right pulse crops for a specific field based on the cost benefit analysis and designing schedules for irrigation and fertilization. This system may help farmers in the absence of an expert or it can also assist the human agricultural expert. The reasoning mechanism will be employed by the system to interpret and apply rules. The proposed system will be made up of two main integrated components: advisory and strategic.
The advisory component will consist of two subsystems : diagnosis and control measure. The diagnosis subsystem will be used to identify diseases and insect-pests. The control measure subsystem will recommend most appropriate treatments for the identified diseases and insect-pests.
The strategic component will consist of three subsystems, namely: fertilization, irrigation, and crop economic. Each subsystem will work with its own database. There will also a common database, which will allow the combination and sharing of outputs from some subsystems. The fertilization subsystem will generate a fertilization regime, including fertilizer type, dose, and application time, based on soil fertility, preceding crops, water quantity, planting type, and other factors. The irrigation subsystem will produce a schedule for irrigation, including quantity, intervals, and irrigation time. It will take into consideration soil type, soil salinity, water quality, precipitation, and temperature, for particular agro-ecological niche. The crop economic subsystem will help farmers/users to carry out cost benefit analysis for pulse crops, including cost of cultivation, expected yield (quintal/hectare), and prices (Rs./quintal). It can be used to seek advice on selecting the right pulse crop in the right season for a specific field.
