Rice is a major food crop for a significant population of the world and increase in its yield is a priority to ensure nutrition for many countries. Thus it is important to protect the crop from the various diseases that affect the crop. With the advent of machine learning, a number of methods have been proposed to identify diseases after the occurrence as well as at an early stage. Diagnose of these predators before occurrence can be much more beneficial. Journal papers that used rice as a major crop were considered eligible. In this review, an attempt is made to understand the preferred machine learning methods and algorithms that can be employed to detect various diseases and pest as well as predict crop yield of the rice crop. It is expected to be beneficial to all who wish to use machine learning in agriculture that can lead to constructive research in this area.

Enabling embedded System developed for working in a network environment can provide a lot of opportunities in monitoring and controlling of same from different geographical areas. It may be in a peer to peer type or client server type depending on type of application. Adding web features for such an application, system will be accessible from anywhere from the web. System developed here mainly focus on the issues of possibility of deployment of the system from LAN and Web. Stated study is a microcontroller based embedded system for monitoring and controlling of parameters like temperature and humidity. It can be implemented using simple client server technology as well as web technology. Users belong to the organizational domain can use their own Intranet for monitoring and controlling of parameters designed on simple client server technology whereas users beyond the scope of Intranet can use Internet interface designed using web technology. Both the technologies are having its own advantages as well as disadvantages. This paper explores the technological implications of the system using client server as well as web technology. Embedded hardware circuit is fabricated in to two separate digital circuits connecting two COM ports of Embedded server. First circuit will monitor temperature and humidity and display same in LCD. Application program executed in computer reads COM port and display the same in monitor and store in database. Second digital circuit will provide necessary hardware control of devices for controlling of temperature and humidity automatically. It is implemented through relay based on the user entered set value of temperature and humidity which is stored in database of computer. Developed system enable its both Intranet as well as or Internet users for monitoring and setting new values of temperature and humidity through the respective front end.
