The investigation entitled “Biochemical responses of rice varieties under sodic soil” was conducted during the kharif season in 2015 at the experimental site of Department of Crop Physiology at Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad-224 229 (U.P.) in randomized block design with three replications and eight varieties, four tolerant (CSR36, CSR43, Narendra Usar 3, NDR 2009) and four susceptible (Swarna sub 1, IR28, IR64, IR29). Evaluate the performance of tolerant varieties and susceptible varieties in sodic soil. Observations were recorded at 60, 90 DAT and maturity. Results indicate the biochemical characters such as chlorophyll content, proline content and catalase activity was increased in tolerant varieties and decrease in susceptible varieties. Tolerant varieties have less accumulation of sodium (Na+) and maintain better level of potassium (K-) under sodicity while, reverse is true for sensitive ones. CSR36 and CSR43 had a greater tolerance to sodic soil than IR64 and IR29.
