YIELD AND QUALITY OF DIFFERENT RICE (ORYZA SATIVA L.) VARIETIES AS AFFECTED BY SOIL SALINITY

IMDAD ALl MAHMOOD, R.H. QURESI* AND M. ASLAM*

Abstract: A pot experiment was conducted using six rice varieties viz., NR-I, 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 NaCI salt. Basal dose of NPK and ZnSO₄ 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.
