Mandate of the Station

  • To evolve high yielding and quality rice varieties suited to upland, semidry and irrigated conditions
  • To evolve varieties tolerant to saline, alkaline and coastal inland situations
  • To produce nucleus and breeder seeds in rice viz., TKM 9, TKM 11 and TKM (R)12, ADT 43, ADT (R)45 and in groundnut TMV 7
  • To identify the genotypes  resistant to blast, bacterial leaf streak, Rice Tungro Disease, rice leaf folder and rice black bug
  • To develop Integrated Nutrient Management practices and Integrated Pest and Disease Management strategies
  • To produce and supply ornamental plants, fruit seedlings and vegetable seeds for the citizens in and around Chennai city
  • To cater the needs of extension functionaries and farming communities of both Thiruvallur and Kancheepuram Districts
  • To coordinate the extension activities in collaboration with allied departments

Agronomy

  •  Growing of Black gram in sornavari (April – May) , rice in samba(August – September) and groundnut in navarai (December – January) was found to be profitable cropping system in Thiruvallur and Kancheepuram districts
  • Summer ploughing followed by spraying of thiobencarb @ 2.5l/ha at 8 DAS controlled weeds effectively in rainfed rice
  • Growing of rice and blackgram at 4:1 ratio was economical under rainfed farming in samba season
  • System of Rice Intensification(SRI) gave higher yield with low input 

Crop Physiology

  • Seed hardening agents viz., 1% KCL, DAP, ammonium molbdate, calcium chloride, potassium dihydrogen phosphate and 10% solution of cows urine and garlic extract enhanced germination, tillering ability and grain yield in rice varieties

 

Agricultural Entomology

  • To control black bug, acephate 625g/ha or monocrotophos 1000 ml/ha or neem seed  kernel extract 5% is recommended
  • For the control of early pests like hispa, whorl maggot and gall midge soaking the seeds in water for 10 hours and then in a solution of 8% zinc sulphate+ 0.1% methyl demeton for 12 hours was very effective.

 

Plant Pathology

  • For the control of bacterial leaf blight and bacterial leaf streak, streptocycline sulphate and tetracycline mixer 300g/ha + copper oxy chloride 1250g/ha has to be applied during tillering stage
  • To control Rice Dungro Disease monocrotophos 1000ml/ha isrecommended
