Diagnosis of disease on paddy field with the help of web based expert system

This expert system gives advice to Paddy growers in India to improve Paddy productivity. The system contains two main parts namely: strategic part and evaluation part. The strategic part gives a strategic advice (i.e. list of symptoms)after cultivating Paddy crop. The evaluation part diagnoses the disease name and name of pest that occursafter Paddy growing season and gives advice about how to control these problems. This paper proposed a new approach which combines the element of fuzzy, image and expert system to develop an image-based expert system in diagnosing paddy diseases. This system aims to provide a guide to identify deficiency of nutrients in crops, i.e., disorders in leaves, stems and roots of a plant. The roles, management, symptoms, quantification, critical limits etc. are parameters which will be used to identify the micronutrient deficiencies in the diseased crops. This will help the ultimate user to find remedies to correct the deficient plants
