Abstract: The present investigation was conducted in the net house of Department of Crop Physiology at Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.). The experiment was carried out in pot culture in complete randomized block design with three replications and six rice varieties, (Three tolerant varities-CSR 36, CSR 43, Narendra Usar 3) and (Three susceptible-Swarna Sub 1, IR 28, IR 29) under sodic soil having pH 8.5-8.6, 9.0-9.1 and 9.5-9.6. Results of the experiments indicated that chlorophyll, carbohydrate and starch content in leaves showed minimum reduction in all the tolerant varieties at pH 9.5 in comparison to susceptible varieties at flowering stage of observation. Tolerant varieties have less accumulation of Na+ and maintain better level of potassium at higher sodicity levels while, reverse in case of sensitive varieties. CSR 36 and CSR 43 had a greater tolerance to sodic soil than IR 64 and IR 29.
