Abstract: The on farm testing (OFT) experiment was conducted at farmer field of Uppukottai Village of Theni District during Rabi 2018 -2019. The experiment trail was conducted to assess the suitable salt resistant rice variety for saline soils of Theni district. The experiment was laid out in a Randomized Block Design (RBD) and replicated thrice with following three treatments; T₁ - Farmers practice (Goraknath 509), T₂ - CSR 43, T₃ - TRY 3. There are two salt resistant varieties namely, CSR 43 and TRY 3 was used in this experiment trail. The recommended doses of fertilizer were applied at the time of field preparation as a basal dose. Each trail plot was conducted in 0.4 ha. The primary data collected from the farmers with help of the interview schedule and direct field measurement. All the yield components such as number of productive tillers, panicle length, panicle weight and test weight with values of 31, 21.4 cm, 2.6 g and 24.7 g were higher with the TRY 3 salt resistant rice variety (T₃) followed by, salt resistant rice variety CSR 43 (T₂) with number of productive tillers (26), panicle length (18.6 cm), panicle weight (2.1 g) and test weight (22.5 g). TRY 3 salt resistant rice variety (T₃) recorded higher grain yield (4828 kg ha^-1) and straw yield (5340 kg ha^-1) followed by, CSR 43 salt resistant rice variety (T₂) gave grain yield (4235 kg ha^-1) and straw yield (4860 kg ha^-1). The highest B: C ratio (2.13) was recorded with the TRY 3 salt resistant rice variety (T₃). The above study reveals that, salt tolerant variety TRY 3 could be considered as a better option for achieving higher production and profitability of rice under the saline soils of Theni District.
