Yield and quality of different rice (Oryza sativa L.) varieties as affected by soil salinity

A pot experiment was conducted using six rice varieties viz., NR-1, IR-6, NIAB-6, KS-282, Basmati-370 and Basmati-385 to determine their yield potential and quality under non-saline (1.7 dS m(-1)) and saline condition (10 dS m(-1)) by adding appropriate amount of NaCl salt. Basal dose of NBK and ZnSO(4) respectively was applied. On an average, the grain yield of rice varieties was reduced by 30% with salinized soil over the normal soil whereas, protein content in rice grain was greater on salinized soil. Among the varieties, NIAB-6 gave better performance with improved grain yield as well as protein contents of both straw and grain.
