Fuzzy logic (FL) has emerged as an important branch of Expert system which has proved to provide solution to real life problems that had remained unsolvable otherwise. It has found wide range of applications in diversified areas. In this paper, we study how the methods of fuzzy logic have been effectively used to solve a myriad of problems in the field of agricultural sciences. This paper reviews a few of the applications of fuzzy logic integrated with expert systems which had been applied in the field of agricultural sciences. This study could be considered as a part of the literature survey done for research work in future for developing expert system for a particular crop for a given region in our country. It can serve as the baseline for further work to be carried out in this domain.
