and maintained by eExtension Unit
Received ‘Best e-Governance Award’ for the year 2011-12
The portal provides technologies for crop production,
animal husbandry
Hosts success stories of farmers and farmers’ innovations
Information on Government schemes, credit facilities and
special technologies for entrepreneurs
The portal is updated on daily basis and visited by
thousands of farmers, technologists, administrators and
extension personnel every day
The e-Extension Centre has multiple video conferencing
facility and connects to all the TNAU College campuses,
Agricultural Development Centres
Market Intelligence
 Domestic and Export Market Intelligence Cell offers
advisory services on marketing
 Registered farmers receive prevailing prices in
different local and export markets for the
produces/products of their interest
 Forecasts price for agricultural produce and value
added products
 Collects Cost of Cultivation of Principle Crops
 Maintains a database on price of agricultural
commodities from the leading markets of Tamil Nadu
and neighbouring States
