Rice Research Station, Ambasamudram (8°42’0 N, 77.480 E and 64.8 MSL), is vested with the responsibility of research in rice breeding, management and protection to cater the needs of Thamirabarani river basin farmers. There are four scientists working in the station and twelve projects viz., one TNAU core funded research project, eight university research projects, one venture capital scheme (Seed production) and two TNINAMP projects, are being operation. During 2018-19, in rice breeding two early duration rice cultures viz., AS  16004 (Manjalsaradai/ASD 16) and AS 13228 (ADT 37/BPT 5204) ; two mid early duration cultures viz.,  AS16050 (ADT 38 / BPT 5204) and AS 13203  (ADT 37/ BPT 5204) found promising for yield and quality in station trials were  advanced to Multi Location Trials 2019-20. One early duration rice culture  AS  15024 (ASD 16/Manjalsaradai) recorded a mean grain yield of 6080 Kg/ha  in  Multi Location Trials  2018-19 with 15% superiority over the check. In seed production, 7494 kg of breeder seed, 4050 kg of foundation seed, 1050 kg of certified seed and 15 tons TFL seed were produced in rice. In pulses seed production 500 kg black gram foundation seed was produced. In Host Plant Resistance research for Bacterial Blight disease, ten rice cultures with resistant reaction were identified. In the extension activities, 57 farmers oriented training on paddy production technology and one field day on Certified Black gram seed production were organized. To strengthen the water resources a new bore well to a depth of 300 feet was drilled.
