Welcome to Agricultural Research Station, Paramakudi

Agricultural Research Station, Paramakudi is located in the southern bank of the river, Vaigai on Madurai - Rameswaram National Highway. In 1952, it was established as Research station under State Department of Agriculture. Then, it was recognized as Paddy research Sub-center from 1952 to 1958. Later it was changed as State Seed Farm from 1958 to 1978. Again it was renamed as Multi-Crop experiment sub-station from 1978 to 1981.  Finally it was established as Agricultural Research Station under Tamilnadu Agricultural University from 1981 on wards.

            Agricultural Research Station, Paramakudi represents rainfed tracts of Ramnad and Sivagangai districts of Tamilnadu. The extent of the experimental farm is about 9.36 ha, which is located at latitude of 9 21N and longitude of 78 22E and an altitude of 39.83 m MSL. Annual average rainfall is 740 mm of which 60 per cent is received from Northeast monsoon. Soil type is clay loam low in available nitrogen, medium to high phosphorus and potassium. The organic matter content of the soil is very low. Soil is slightly saline with a pH of 8.0

Matures in 110-115 days

Drought tolerance and non-lodging

Tolerant to water inundation

Grain yield: 3200 kg/ha under rainfed condition

Suitable for both dry and semi-dry systems of cultivation in Ramnad and Sivagangai districts.

Chilli    : PMK-1

Released during 1994

Suitable for rainfed conditions

Yield: 2400 kg dry pods per hectare (53% increased yield over the local)

Duration: 200 days

Conical fruits with attractive red colour

Fruits contain 0.36% capsaicin


Crop Management

         Second fortnight of September (38th and 39th Std week) is suited for direct sowing of rice in Ramnad District

         Paddy intercropped with greengram at 6.2 ratio is the most remunerative system under semi-dry condition

         Application of NPK as per soil analysis along with enriched FYM @ 750 Kg/ha and 4 Kg (20 pkts) each of Azospirillum and Phosphobacteria gave higher yield under semi-dry paddy

         Pre-emergence application of Oxyflourfen @ 0.15 kg a.i/ha is most effective in controlling weeds in rainfed chilli


Crop Production

         Basal application of neem cake @ 100 kg/ha, release of Trichogramma chilonis @ 5 cc/ha on 40,47,54 and 61 DAS and T.japonicum on 67,74,81 and 88 DAS and spraying NSKE 5% at 50% ETL controlled the major pests of Semi-dry Paddy

         Neem oil 1% or neem cake extract 5% is effective in controlling chilli aphids

         Dimethoate 0.03% or neem oil 1% or neem cake extract 5% is effective in controlling chilli thrips

         Dicofol 0.03 % or Phosalone 0.07% is effective in containing yellow mites in chilli

         Ethanolic or Hexane extract of Neem Seed Kernel at 1% are effective in controlling aphids and thrips in Chilli
