We had used the latest technology like “Prediction using K-means” based on last several decades of data as well as “Rule based prediction using fuzzy logic”. We had also compared the result of both the process. There are number of algorithms for prediction purpose. But, we used K-means algorithm for prediction because predicted rainfall is based on last several decades of data year by year. On using K-means algorithm we got the more accurate or actual or probable prediction. Another prediction is done on the basis of rule base system using fuzzy logic by applying rule on land used for farming, rainfall and production with the help of inference engine.
