OILSEEDS RESEARCH STATION, TINDIVANAM


GENESIS

v  Pioneer research station in Tamil Nadu exclusively for oilseeds.
v  Started as Agricultural Research Station in 1935.
v  Upgraded as Regional Research Station in 1962.
v  Renamed as Oilseeds Research Station (ORS) and brought under Tamil Nadu Agricultural University in 1981.

v  C. Subramaniam Institute of Agriculture for Diploma programme was started during 2004.

Mandate 

   

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

v   To develop crop management technologies for the released varieties.

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

v  To develop improved weed management practices.

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

v  To produce nucleus and breeder seeds of improved groundnut, sesame, castor, black gram and moth-bean varieties.

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

v  To determine the effects of continuous application of single and combined application of Organic and Inorganic fertilizers on the nutrients availability of soils

v  To find out suitable micronutrients and bio-fertilizers for augmenting the yield.

v  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.

Technologies developed

  Technologies developed

  29 high yielding pest, disease and drought tolerant varieties have been released (Thirteen in groundnut; Seven in sesame Seven in castor and Two in pulse crop).

v Nine tyned tractor drawn TNAU seed drill for groundnut sowing was successfully demonstrated

v Intercropping systems of highly profitable were developed. 1:6 Black gram – Groundnut; 1:6 Castor – Groundnut; 1:4 pearl millet – Groundnut.

v Dual spraying of Glyphosate 1% (post-emergence) 15 days prior to sowing followed by pre-emergence application of metolachlor 2 1 kg ai/ha on third day after sowing controlled weeds efficiently.

v Summer ploughing followed by glyphosate spray effectively controlled Haryali (Cyperus rotundus) weed.

v Groundnut seed hardening with calcium chloride 0.5 per cent induced drought tolerance and increased the yield.

v Application of dried sugarcane trash @ 5 t/ha as mulch increased the yield of groundnut and castor.

v A manorial schedule of 10:10:45 NPK 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 25.50.75 N.P.K. kg/ha.

v Application of gypsum at 200 kg/ha as basal and 200 kg/ha as top dressing at45th day increased the groundnut yield.

v Application of nutrient spray containing a mixture of diammonium phosphate 2.5 kg, ammonium sulphate 1.0 kg, borax 500 g and planofix 400 ml. per ha or groundnut rich @ 2 kg per ha at 25th and 35th day after sowing increased groundnut yield.

v Enriched farm yard manure @ 750 kg/ha is recommended in the case of non availability of bulky farm yard manure.

v Ten per cent infested leaflets was found to be the economic threshold level for groundnut leaf miner (GLM).

v Intercropping castor with groundnut in 1:6 or 1:10 ratio reduced Spodoptera incidence.

v Intercropping pearl millet with groundnut at 1:4 ratio reduced GLM incidence.

v Spraying of Carbendazim 50 WP 250 g/ha plus Mancozeb 1000 g/ha was effective in reducing rust and late leaf spot of groundnut.
