The principal landmark in the history of tea research in south India, was the establishment of a Tea Experimental Station in Gudalur in 1926. During the last seven and half decades, this research organization, now known as the UPASI Tea Research Foundation (UPASI TRF), had rendered yeomen service to the tea industry in south India. The remarkable achievements of the south Indian tea plantations in the production and productivity of tea bear testimony to the significant contribution of UPASI TRF in the fields of research and extension.

The UPASI Tea Scientific Department witnessed a very important event in 1999. The UPASI found it necessary to form a separate Tea Research Foundation (hereafter TRF) for better administration of scientific research pertaining to cultivation, production and processing of tea and other allied aspects.

The Tea Research Institute is located near the Nirar Dam in Valparai, in the Anamallai Hills, Coimbatore District, Tamil Nadu while the administrative/registered office is located in Coonoor, The Nilgiris.


Immediately after post independent era, India occupied a premier position in tea trade. Presently we lost our first position in production, productivity, area under tea and international trade, except production of huge quantum of CTC tea production. In order to retain the prestigious position in the world tea map and to compete in the domestic and international market UPASI TRF will serve as a core organization of tea industry and promote the tea trade in near future.


At the moment, due to ever spiraling costs of agricultural input and scarcity of labour force, the industry is facing grave situation. Climatic change or shift in climatic variables is yet another cause that determines the productivity due to sudden outbreak of secondary pests and diseases. In recent years, tea planters are not realizing the marginal profit out of their intensive agricultural operations.
