  • Growing blackgram in Sornavari (April-May), rice in Samba (August - September) and groundnut in Navarai (December - January) was found to be profitable in Tiruvallur and Kancheepuram districts.

  • Growing rice and blackgram in 4:1 was economical under rainfed farming in Samba season.

  •       Summer ploughing followed by spraying of Thiobencarb @ 1.5 kg a.i/ha 8 days after sowing effectively controlled the weeds in rainfed rice.


  • Application of phosphorous at 75% recommended level of STCR value either as DAP or Super phosphate along with Phosphobacterium and Azospirillum significantly increased the grain yield (15%) in irrigated rice.

  •       Foliar spray of 0.5% ZnSO4, 0.25% FeSO4, 0.1% MnSO4 and CuSO4 on 20, 40, and 55 DAT along with basal application of Azospirillum and Phosphobacterium @ 2 kg/ha gave 20% increased yield in irrigated rice in  all the seasons.


  •       Rice entries were not able to survive at 12 dS/m salinity.                          

  •       The yield reduction due to salinity ranged from 29 to 100 percent.                                   

  •       The grain straw ratio decreased from 0.58 to 0.23 amounting to 61 percent reduction, because of salinity.                                   

  •       Seed hardening agents viz., 1% solution of KCl, DAP, ammonium molybdate, calcium chloride, potassium  dihydrogen   phosphate and 10 per cent solutions of cows urine and garlic extract enhanced germination, tillering ability and grain yield in TKM 11 and PMK 1 .                

  •       Irrespective of rice entries viz., TKM 11,PMK 2 and ADT 36 the yield was affected under mid-drought stress (55%) followed by early drought (44%) and late drought (11%) compared to control.                             


  • Rice planted in June increased the greenleafhopper activity which in turnincreased the RTD.

  • Spraying of Neem Seed Kernel Extract (NSKE) 5% and Ipomoea Spp leaf extract 10% at 10 days interval from panicle initiation effectively controlled the earhead bug damage.

  •       A complete management practices were evolved for Rice black bug. Spraying neem seed kernel extract 5% or Acephate 625 g /ha@ 10% ETL was highly effective against rice black bug.


  • Foliar spray of leaf extracts of Vitex negundo  10% or Prosopis juliflora  10% was  highly effective for brown spot and grain discolouration.

  • Leaf extract of Aegle marmelos (Vilvum) 10% as spray effectively checked the leaf blast and neck blast in rice.

  • Seed treatment with Carbendazim (0.05%) reduce the Fusarium root rot in nursery.

  •       Spraying Edifenphos @ 500 ml/ha at 30, 45 and 60 DAT was very effective for blast, sheath rot and leaf spot.

  • Combination of Streptomycinsulphate and Tetracycline @ 300 g/ha + Copperoxy chloride @ 1250 g/ha at maximum tillering stage effectively controlled the bacterial leaf blight and bacterial leaf streak in rice.


  • v Plant clinic centre (PCC) scheme is functioning at this station since 1986 with the following objectives:

  • v Identification  of field problems and suggesting suitable remedial  measures by making regular field visits and joint field inspections.

  • v Conducting Off/On   campus training  programmes.

  • v Imparting    training   on latest   techniques to farmers and   extension workers.

  • v  Pest and   Disease surveillance meetings.

  • v Imparting training on Oyster and milky mushroom cultivation to unemployed youth and  farm women

  •     v Dissemination of technologies through mass media.

      v Publication of popular articles in newspapers and farm magazines and distribution of extension literatures.

    v Transfer of latest farm technologies through monthly zonal workshops.

    v Adoption of villages under TNAU-IVDP in which the farmers are motivated to adopt the proven technologies.






    v  Popularised   drum  seeder,groundnut decorticater ,parboiler and ridge former
