Approach is like a doctrine for the system, which informs, stimulates and guides such aspects of the system as its structure, its leadership, its program, its resources and its linkages. Agricultural Extension is an instrument of change. It enables farmers to seek and adopt desirable changes in farming. The basic function of agricultural extension is to relate new knowledge to the needs, problems and opportunities of farmers. The two extension systems dealing with the commercial and subsistence segments should, therefore, be different in their goals, competence and strategies. Commercial segment farmers have to be served by a specialized Extension Service and the subsistence segment farmers are served by the General Extension Service. ICT tools are extensively used in agricultural extension during the last two decades. Many pilot projects have succeeded in the field. Rural Advisory Services (RAS) refer to all the different activities that provide the information and services needed and demanded by farmers and other actors in rural settings, to assist them in providing their livelihoods by developing their technical, organizational and management skills and practices. Recently, a new extension approach christened as disruptive extension comes into the limelight which is considered as an innovative extension approach that creates a new paradigm of extension that eventually disrupts an existing approach followed by extension professionals in the field of agriculture and allied sectors. The market-led extension is also a new approach, deals with all these parameters from production to marketing of agricultural produce.
