Research Stations


Welcome to Oilseeds Research Station, TINDIVANAM
  • Pioneer research station in Tamil Nadu exclusively for oilseeds.
  • Started as Agricultural Research Station in 1935
  • Upgraded as Regional Research Station in 1962
  • Renamed as Oilseeds Research Station and brought under Tamil Nadu
  • Agricultural University in 1981

  • To evolve groundnut, sesame and castor varieties with desirable attributes viz., shorrt duration, high yield, high oil content, drought tolerance, fresh seed dormancy, resistance to major insect pests and diseases etc.,

  • To develop crop management technologies for the released varieties.

  • To identify the best crop rotation and inter crop suited for the zone.

  • To develop improved weed management practices.

  • To find out suitable micronutrients and biofertilizers for augmenting the yield.

  • To screen cultures and genotypes so as to identify resistant types.

  • To evolve integrated insect pests and diseases management practices.

  • To test the efficacy of bio-products and new chemical formulations against insect pests and diseases.

  • To produce nucleus and breeder seeds for supply to State Department of Agriculture with respect to TMV 2, 7  and 10 in groundnut, TMV 3,4,5 and 6 in sesame and TMV 1 blackgram.

  • To produce breeder seeds of TMV 5 and 6 castor for supply to State Department of Agriculture.

  • To monitor the groundnut breeder seed programme at State Oilseeds Farm, Musaravakkam.


  • Twelve high yielding groundnut varieties TMV 1 to 12 were   released.  This includes six bunch, three semi-spreading and   three   spreading  varieties.  TMV  2  is a bunch variety with wider adaptability and is under cultivation in Karnataka, Andhra Pradesh and Gujarat also. TMV 10 is a semi-spreading  variety with highest oil content (54%).

  • Six high yielding sesame varieties TMV 1 to 6 were released TMV 3 is a versatile variety suited for all seasons. TMV 5 is suited to cold weather season while TMV 4 and 6 are suited for summer season.

  • Six high yielding castor varieties TMV 1 to 6 and one castor hybrid TMVCH 1 were released.

  • One high yielding blackgram  variety TMV 1 was released.  It is  a short duration variety suited for districts in the North Eastern Zone.

  • Nine tyned tractor drawn seed drill developed by Tamil Nadu Agricultural University for groundnut sowing was successfully demonstrated as profitable and saves much time and labour.
  • The following Inter-cropping systems which were highly profitable were developed.  1:6 Blackgram - groundnut : 1:6 Castor - groundnut  :1:4 Cumbu - groundnut.In the case of late receipt of monsoon, blackgram + castor at 6:1 ratio is recommended.
  • Dual spraying of Glyphosate 1% (Post-emergence) 15 days prior to sowing followed by pre-emergence application of metalachlor @ 1kg ai/ha on the third day after sowing controlled weeds efficiently.
  • Groundnut seed hardening with calcium chloride 0.5 per cent induced drought tolerance and increased the yield.
  • Summer ploughing followed by glyphosate spray effectively controlled Cyperus rotundus
  • Raising castor by forming ridges 60cm apart and furrows of 30 cm width, 15 cm depth is better than flat bed method.
  • Application of dried sugarcane trash @ 5t/ha as mulch increased the yield of groundnut and castor.
  • On farm trials and front line demonstrations were conducted in castor to popularisethe varieties, hybrids and production technologies.
  • A manurial schedule of 10:10:45NPK kg/ha with 6.25 M.T. of farm yard manure has been developed for rainfed groundnut.  For irrigated groundnut, the schedule was fixed as 17:34:54 N.P.K. kg/ha.
  • Application of gypsum at 200 kg/ha as basal and 200 kg/ha as top dressing at 45th day increased the groundnut yield.
  • Application of nutrient spray containing a mixture of diammonium phosphate 2.5 kg, ammonium sulphate 1.0 kg borax 500g and planofix 400 ml per ha. at 25th and 35th day after sowing increased the groundnut.
  • Enriched farm yard manure @ 750 kg/h is recommended in the case of non availability of bulky farm yard manure.
  • Ten per cent infested leaflets was estimated to be the economic threshold level for groundnut leafminer (GLM).
  • Inter-cropping cumbu with groundnut at 1:4 ratio reduced GLM incidence.
  • The parasite Gonozius sp was found to be potential in reducing GLM incidence.
  • Grade 3 was estimated to be the critical level for the application of fungicides to groundnut diseases.
  • Spraying of carbendazim 50 WP 250 g/ha plus mancozeb 1 kg/ha was effective in reducing rust and tikka leaf spot of groundnut.
  • Conduct of monthly Zonal Meeting of Villupuram District.
  • Conduct of Farmer's Day.
  • Conduct of training to rural women on the preservation of Food & Vegetables,
  • through NATP programme.
  • The station has completed 60 years.  In order to commemorate the occasion, the diamond jubilee was celebrated on 24.11.1997, in which Honourable Miister of Agriculture, Tamil Nadu participated.

Future Thrust

  • Breeding for quality attributes in groundnut and sesame with particular emphasis on rainfed conditions with resistance/tolerance to biotic and abiotic stresses.
  • Production of nucleus and breeder seeds of promising varieties released from the station.
  • Undertaking water technology studies for rainfed oilseed crops.
  • Developing Agri-Horti and Agri-Sylvipasturl systems suitable for the region.
  • Developing integrated pests and diseases management practices for rainfed conditions.
  • Coordinating the extension activities in collaboration with sister and allied State
  • departments viz., Department of Agriculture, Department of Horticulture and Plantation crops, Department of Seed Certification etc.,
