Effect of sodicity on biochemical traits of tolerant and susceptible rice (Oryza sativa L.) varieties

Abstract

Present investigation entitled “Effect of sodicity on Biochemical traits of tolerant and susceptible rice (Oryza sativa L.) varieties” was conducted during kharif season 2016, at the experimental site (MES), Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad-224 229, (U.P.). The experiment was carried out in field with four varieties of rice i.e. CSR36, Narendra usar dhan-3(tolerant), IR-28 and Swaran sub-1 (susceptible), three soil type viz. control (8.0-8.5pH) and (8.5-9.0pH) and (9.0-9.5pH). The experiment was laid under Randomized block design (Factorial) with three replications. Results of the experiment revealed that sodicity decreased Sodicity significant decreased the total chlorophyll content in leaves. Sodicity tolerant varieties showed higher total chlorophyll content as compared to susceptible ones at all the stage of observation (seedling established, 3rd, 6th, and 9th DAT) in all the rice varieties at all the stage of the observation. Sodicity tolerant varieties, CSR36 and Narendra user-3 showed minimum reduction in all traits under sodicity, however, susceptible, IR28 and Swarana sub 1 sowed maximum reduction.
