NaCl- and Na2SO4-Induced Salinity Differentially Affect Clay Soil Chemical Properties and Yield Components of Two Rice Cultivars (Oryza sativa L.) in Burundi

Salinity may strongly influence the interaction between plant roots and surrounding soil, but this has been poorly studied for sodium sulfate (Na2SO4). The aim of study was to investigate effect chloride (NaCl) Na2SO4 salinities on soil chemical properties as well rice physiological- yield-related parameters two contrasted cultivars (V14 (salt-sensitive) Pokkali (salt-resistant)). Pot experiments were conducted using electrolyte solutions, namely NaCl Na2SO4, inducing electrical conductivity levels (EC: 5 or 10 dS m−1) solutions. control treatment water with salt-free tap water. Our results showed that pH increased under salinity, while EC level saline stress increased. induced an increase in Na+ concentrations solid complex solution. reduced stomatal density salt-sensitive cultivar. total protein contents grain higher V14 than Saline significantly affected all more toxic most parameters. exhibited a tolerance V14, whatever considered type salt. It is concluded different types salts differently responses those differences partly depend salt-resistance
