Looking for high resistance to saline-sodic soil conditions under different systems, six rice Oryza sativa L. varieties were evaluated (CICA 4 - CICA 8, IR 253-26-3-5-2, IR 22, IR 26 and Pokkali). IR 2153-26-3-5-2 appeared as the most tolerant and showed the highest yields under all planting syst...
