The Tamil Nadu Rice Research Institute (TRRI), Aduthurai in Thanjavur District, have urged farmers to plan ahead for samba and Thaladi seasons using region-specific, low-input paddy varieties.
TPS 5, a commonly used variety in the delta, matures in 100 days elsewhere, it takes 125 days in the delta.
It was causing delayed harvests, higher pest incidence, and increased costs.
TRRI recommended kuruvai varieties such as ADT 53, 55, 56, and 57.
ADT 57 is suitable for direct sowing and ADT 55 offers Bacterial Leaf Blight (BLB) tolerance.
ADT 53 is a good alternative to ADT 43 for parboiled rice, and ADT 59 is preferred for idly rice.
For saline and coastal tail-end areas, TRY (Tiruchi Rice) varieties 1 to 5 are ideal.
For flood-prone delta areas, he recommended CR1009 Sub 1.
