The beginning of a new era of tea research in India was marked by the establishment of the Scientific Department of Indian Tea Association (ITA) in the year 1900. This was consolidated with the creation of the Tocklai Experimental Station in 1911. The formation of the Tea Research Association (TRA) in 1964 with Tocklai at the centre of all activities further expanded the horizon of tea research to cover the entire Northeast India. Research on all aspects of tea cultivation and processing is carried out at Tocklai Experimental station, Jorhat the oldest and the largest research station of its kind in the world. Transfer of technology to its member estates is carried out through its advisory network covering 1076 tea estates occupying 3,41,049 ha of land spread over The South Bank, North Bank, Upper Assam, Cachar, Tripura, Dooars, Darjeeling and Terai. Tocklai has its substation at Nagrakata. Membership is voluntary.
