Rough Set Theory (RST) is innovative mathematical techniques for dealing with inexact, imprecise knowledge. RST was delivers powerful several interesting applications that can be used for a wide range of purposes. This paper studies strength, certainty factor, and coverage factor of the decision rule signifies a though flow the relevant branch. In this article used rough set based techniques in agrarian fields. A proposed task we sort out better sugarcane varieties for planting using rough set theory. Certainty factor of the decision rules and coverage factors of the decision rules to find out varieties. Using RST the outcome we got convinces that the agrarians used sugarcane varieties , , and .
