Ever since 1976, the Tea Board started funding the time bound projects like “Chemistry of tea clones”. A Lion’s share of funds contributed by the Tea Board/Commerce Ministry as grant-in-aid besides UPASI TRF receives grant from various government agencies for time bound research projects. Government agencies which fund for research projects are the Tea Board, National Tea Research Foundation (NTRF), Department of Biotechnology (DBT), Department of Science and Technology (DST), Council of Scientific and Industrial Research (CSIR), Ministry of Agriculture, Ministry of Chemicals and Fertilisers, Sulphate of Potash Information Board (SOPIB), Washington, Green Tea Research Association, Japan and O-Cha (Tea) Pioneer Academic Research Grant Programme, Japan. The Indian Council of Agricultural Research had also granted adhoc research projects. The status of the projects conducted by various divisions of UPASI is presented here under.
