Agricultural Sciences is an Applied Science but has its touch with social science due to its nature. It uses various kinds of tools, techniques, procedure, methods, principles of science; that is responsible for the cultivation of plants, crops, vegetables, livestock as well as animals. Agriculture is dedicated to the sedentary human civilization and by this people can meet their food demand. As far as the history of agriculture it is noted that agriculture as a concept emerged thousands of years before about 105,000 years ago and regarding the nascent farmers, it was about 11,500 years ago. Initially, animals were not considered within this but gradually various animals such as pigs, sheep and cattle became part of agricultural sciences since 10, 000 years ago. Farming normally considered as the cultivation in a small area whereas Agriculture is treated for a large area with huge place and expenditure. In today’s context, about 11 regions of the world are cultivating commercially. Agriculture as an interdisciplinary field is concerned with various disciplines and subjects; and this trend is growing rapidly. There are diverse areas and emerging nomenclatures emerged in Agriculture viz. Chemical Agriculture, Green revolution & Agriculture, Genetic engineering-based Agriculture, Organic Agriculture /Farming, Corporate Agriculture /Farming, Vertical Farming /Agriculture, etc. This paper is theoretical and empirical in nature. It analyzed various aspects of agriculture with special reference to the aspects, features, role, and emergence of three emerging types of agriculture viz. Organic Agriculture.
Agricultural Informatics is one of the important emerging domains gaining popularity in recent years. This is simply the application of Information Technology and Computing in Agriculture and allied activities. This is also the combination of ‘Agricultural Science’ and ‘Informatics or Information Science’. This emerging as an interdisciplinary subject and provides solutions for the smarter agriculture and advancement of the agricultural sectors. It is connected with various kinds of information and technological tools. In the recent past, various IT components have emerged and all these are responsible for the agricultural activities leading to cultivation; its enhancement, productivity, quality, cleanliness, efficiency, post agricultural activities. The Agricultural Informatics is responsible for the design, development, management and implementation of the advanced and intelligent agricultural systems, that may call as ‘Smart Agriculture’ or it may be called as ‘Digital Agriculture’. For the creation of such agricultural systems, various emerging Information Technological tools and technologies are emerging and among these important are Cloud Computing, Big Data, Internet of Things (IoT), Robotics & Artificial Intelligence, Human Computer Interaction, etc. Internet of Things (IoT) is applicable in designing and development of healthy and intelligent information systems that are connected with the internet and similar systems. IoT is responsible for various kinds of Agricultural development activities. This paper is conceptual in nature and deals with a brief overview on Agricultural Informatics including evolution, features and role and importance in the concentration of its applications in the creation of ‘Smart Agriculture’ and also emphasized how IoT and similar systems are helpful in promotion of Agricultural activities, intelligent and smarter way. Paper also highlighted about the issues, challenges and concerns on Agricultural Informatics with special reference to its IoT applications in Agriculture towards the promotion of Smart Agriculture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
