A study was conducted at Mona Research Experimental Project, Bhalwal, Pakistan, to investigate the effect of sulfurous acid generator (SAG) treated water on the physical and chemical properties of the soil and crop yield. A skimming well with 16 strainers was installed at the farm. The discharge of the well was approximately 28 litres per second with electrical conductivity (EC) of approximately 1.1 dS/m, sodium adsorption ratio (SAR) of 4.3 and residual sodium carbonate (RSC) of approximately 2.8. The RSC of the pumped water was more than the minimum threshold level. Therefore, the water was treated with SAG before application to wheat crop. The pH of treated water varied from 2.5-3.0 and that of mixed water between 6.5 and 7.0. The SAG water improved the infiltration rate up to 84% and reduced the EC significantly. However, there was relatively a small effect on the SAR and soil pH. The wheat yield and water use efficiency was improved with the treated water.
