Agricultural Informatics is a modern and interdisciplinary field of practice and study. It has incorporated from the information technologies, basic technologies and various aspects of agriculture, and horticulture. Agricultural Informatics sometimes refereed as ICT in Agriculture, Agricultural Information Systems, Agro Information Technology, etc, It is dedicated in transforming agriculture sector supported by information driven systems which are supported by ICT). Agro Informatics is responsible in delivering as

well as accessing information. The applications in Agro Informatics in agriculture enhancing agriculture production, nationally and internationally and as a result new practicing concepts been developed called Digital Agriculture and Smart Agriculture. In addition to basic Information Technologies Agricultural Informatics is also supported by different other emerging sub components such as Big Data, Data Analytics, Cloud and Virtualization, Internet of Things, Wireless network with Converged Network, Usability and HCI, UXD, Sensor and Multimedia Systems. Different economical and financial issues are alarming and growing internationally in respect of Agriculture and environment. A proper Agro Informatics practices can lead the development a healthy and sophisticated agricultural systems, and proper applications helps in reaching the status of Digital Agriculture and Smart Farming supported by government, administration, universities, agricultural institutes and associations. This paper highlights the basics of Agro Informatics and Financial aspects related to the Smart Agriculture in Indian context. As a review based work existing works complied and reported here.

Highlights

• Modern farming technology and systems are widely emerging and growing fast for developing smart agricultural systems. Such latest systems and technologies are dedicated in advancing smart decision support systems.
• Apart from basic technologies various latest sub-technologies are important and valuable in advancing agricultural systems including cloud computing, big-data analytics, internet of things, data science, edge computing and fog computing, etc.
• According to a market study it has noted that it was predicted that in our country all type of grains about 275 MT in the year 2017 to 2028. This is worthy to note that India is ranked 2nd (top) producer of the food, and this target would be fruitful in Digital Agricultural Development.
