As is known, agriculture plays an important role in the world economy. Most of the rural population of developing countries rests on agriculture business. India and other developing countries have limited natural resources and high population growth rates. Therefore, this reduction in natural resources gives more importance to the improvement and increase in agricultural production. But this task is becoming more difficult and challenging than before. Therefore, it is very essential to use smart agriculture and technology to get more production from fewer resources. even though the demand is continuously growing, Information and Communication Technology (ICT) offers to manufacturers or producers the adoption of sustainability and development of their daily residing situations. ICTs offers timely and updated relevant information such as weather forecast, market prices, the occurrence of new diseases and varieties, etc. The use of ICTs is considered to be an important pillar for effective agricultural extension. Through ICTs, we can easily reach the technology information of agriculture to the farmers in time and it has proved to be very useful in agricultural extension and advisory services. These advisory facilities play an important role in promoting the production of farmers, enhancing food security, and improving rural life. In ICTs, there is a need to do extensive research on extension service and further strengthen the linkage between farmers which is possible through latest technology. smart farming is being seen as an effective concept in the present time, as IoT sensors have proved to be highly useful in providing technical information about the agricultural fields, and then the user can use the available information and data or inputs. work on the basis. The Smart agriculture system can be operated from anywhere with help of networking technology. To joining process in research and development in Smart Agriculture& Artificial Intelligence (A.I) can be cutting edge technology in data collection and resource optimization.
