Directorate of Research 

The Directorate of research was established in June 1971 to co-ordinate all research activities in TNAU and to administer / monitor the activities of Research Stations situated in different parts of Tamil Nadu. The Directorate is headed by the Director of Research who is supported by scientists from various faculties in carrying out the activities of the Directorate.

Consequent on the formation of Directorate at TRRI, Aduthurai, research stations  in Tamil Nadu has been divided into Region I and Region II.  The 14 Research Stations grouped under Region I as mentioned  below  are under the administrative control of Director of Research, TNAU, Coimbatore.

  1. Regional Research Station, Paiyur
  2. Tapioca and Castor Research Station, Yethapur
  3. Agricultural Research Station, Bhavanisagar
  4. Coconut  Research Station, Aliyarnagar
  5. Agricultural Research Station, Vaigaidam
  6. Agricultural Research Station, Paramakudi
  7. Coastal Saline Research Centre, Ramanathapuram
  8. Regional Research Station, Aruppukottai
  9. Cotton Research Station, Srivilliputhur
  10. Agricultural Research Station, Kovilpatti
  11. Rice  Research Station, Ambasamudram
  12. Agricultural Research Station, Tirupathisaram
  13. Maize Research Station, Vagarai
  14. Dryland Agricultural Research Station, Chettinad

Director of Research is the Nodal Officer for implementing the schemes funded by ICAR and other external agencies including NATP. The procedure for monitoring the University research sub projects in an effective manner through centralized system was dispensed from 2003 and decentralized monitoring system by the respective technical University Officers for effective implementation is presently in operation.  Research projects that are presently operated in TNAU are given tnauprojects.pdf.

Due to decentralization, the schemes, research sub-projects etc. other than Region I are being monitored by the concerned University Officer / Directorate.

The newer research schemes funded by various agencies are implemented at various centres with the approval of the Vice-Chancellor. Generally, these schemes are prepared as University research sub projects and got approved for effective implementation. Besides, University research sub projects are also prepared by the scientists working in the University under Plan and Non-plan scheme on the research aspects that warrants action by the scientists on the day to day issues.



  • Pivotal centre for operating Tamil Nadu Government sponsored activities
  • Nodal Office for ICAR, NAIP, foreign and other private agencies funded schemes
  • Reviewing the completed projects under Research Advisory Committee to finalise the outcome to be either taken for further research or extension activities
  • Co-ordinating / organizing the meetings related to research activities like,
    • Research Council
    • Scientific Workers’ Conference (SWC)
    • Annual Research Workshops for Rice, Millets & Forage Crops, Pulses, Oilseeds, Cotton, Sugarcane, Forestry, Horticulture and Palms
  • Scrutinizing the release of varieties / implements / management technologies by conducting University Technology Release Screening Committee meeting (UTRSC) and Technology and Agricultural Implements Release Committee (TAIREC) 
  • Preparation of consolidated report for State Variety Release Committee meeting
  • Documentation of TNAU research highlights, Scientific Workers’ Conference and Research Council
  • Monitoring & evaluation of all activities in the 14 Research Stations of Region I


Identification of research problems

The problems for research are identified during the discussion in monthly zonal workshops of each districts, Transfer of Technology  centres, Statewide Farmers Interactive meeting, Farmers’ Days in various campuses and Research Stations, State Research and Extension Councils, State Scientific Workers’ Conference in Agriculture, Horticulture, Agricultural Engineering, Forestry and Sericulture where extension functionaries of the state development departments and scientists of the TNAU participate. On knowing the problem of district zonal or state level importance, the scientist (Project Leader) in the relevant discipline in Research Station / Campus is identified to take up research on applied or basic nature. 

Monitoring and evaluation

Individual scientist as per the work load propose projects either to University or to National / International sponsoring agencies. These projects got approved by the Research Project Approval Committee (RPAC) operated at the Directorate / College level.  The progress of the on-going research projects is discussed in the monthly technical meetings and guided by the Professor and Head of the Station / Department.  The Half Yearly Progress Reports of the research projects prepared by the Project Leader, submitted to the concerned Director or Dean are referred to the Technical Directors / Lead Scientists for comments.  Suggestions offered by them are communicated to the Project Leaders pursuing the research projects.

The Director of Research and Technical Directors during their visits to the Research Stations monitor the progress of the research projects and provide guidelines to the project leaders in their research pursuit.

The Vice-Chancellor, the Director of Research and the Technical Directors / Deans monitor and evaluate the progress of the research projects during discussion with the project leader in the Annual Research Workshops of various crops and commodities.

Dissemination of  outcome of Research

The Project Leaders publish the findings from their research projects in various National and International journals which are valued greatly by the scientific community.  They also publish popular articles in Journals and news papers for the benefit of the farming community.

The research findings from research projects are categorized as  (a) for adoption and (b) for on-farm testing presented and discussed in the Annual Scientific Workers’ Conference for transfer of technology.  Further, technologies that have performed consistently well and approved by the bodies for release are grouped under ‘For adoption’ category.  Technologies that are under advanced stage of evaluation are categorized under ‘For on farm testing’.

            The research findings under first category are incorporated in Crop Production Guide every year to update the technologies in this basic and reference document which is used  by all extension functionaries.  Continuous efforts of the scientists in the long run are focused in developing newer crop varieties for the benefit of the farming community to suit the various agro climatic conditions besides tolerating biotic and abiotic stresses.  The number of crop varieties released from this institute till 2012 is furnished below.
