The need for food is rising in tandem with the population's rapid growth. Farmers were unable to meet these standards using their existing ways. As a result, drone technology and other automated techniques were presented. In addition to meeting the world's food needs, these new techniques gave billions of people jobs. Drone technologies reduce the need for excessive amounts of water, pesticides, and herbicides, preserve soil fertility, aid in the effective use of labor, increase productivity, and enhance quality. This paper's goal is to examine how drones are used in agricultural applications. According to the literature, drones can be used for a wide range of agricultural purposes. We employed a thorough evaluation of previous studies conducted worldwide as part of our methodology. The present state of drone technology for agricultural applications, such as crop health monitoring and farm activities including weed control, evapotranspiration estimation, spraying, etc., is compiled in this paper. In order to improve agricultural production, the research article's conclusion is that more farmers invest in drone technology.
