Operations Research is the branch of mathematics in which advanced logical theories and models are studied to enhance in better decision making and optimum utilization of resources. Applications of operations research techniques in the field of agriculture sectors have been the theme of this paper. They are applied to various aspects of agriculture like day-to-day decisions of farmers like choosing the right type of grain, farm planning, cost minimization and profit maximization on an individual farm and also production. This research paper describes various operations research theories and models applied to agriculture, demonstrating them with cases and problems. In this paper we will discuss upon the use of operations research techniques in agricultural area. Although the various techniques/models of operations research are very vast, but here we will put focus on only two techniques Operations Research those are use in Agricultural area.
