A lysimeter experiment was conducted to compare the leaching behavior of varying texture salt-affected soils for salt leaching when irrigated with diverse volumes of good quality water. Lysimeters consisted of PVC (polyvinyl chloride) columns with length of 50 centimeter and diameter of about 11 centimeter. Each lysimeter was filled with 3.0 kg of processed soil. Four treatments of pore volume (T₁ = 1.0, T₂ = 1.5, T₃ =  2.0 and T₄ = 2.5) with canal water. The results revealed that leachate volume increased with increasing pore volume and it decreased significantly with time. More volume was collected from silt loam soil than that from loam soil. The quantity of salts removed in initial leachates was higher which exhibited decreasing trend consecutively within all the treatments from both soils. Maximum salt leaching was noted with 2.0 PV. Soil texture significantly affected the removal of carbonates and more carbonates passed through loam than those from silt loam soil. The leaching pattern of bicarbonates was similar as that of carbonates. The effect of treatments on the removal of Ca²⁺ + Mg²⁺ in leachates was statistically non-significant. Soil texture differed significantly for the removal of Ca²⁺ + Mg²⁺ and more Ca²⁺ + Mg²⁺ leached from silt loam than that from loam soil. The SAR of third leachate was significantly higher than leachates 1,2, and 4. Effect of soil texture was statistically significant and maximum SAR was recorded in leachates from loam compared to that from silt loam soil. Data regarding post soil analysis showed that both the soils responded significantly for the reduction in TSS after leaching of 4 PV of water. The behaviour of both soil textures was different as in loam soil, CO₃^2- concentration decreased whereas it increased in silt loam soil during the study period. After leaching of 4 PV, the soil response for SAR was statistically significant, being maximum for silt loam as compared to loam soil.
