The continuous irrigation of treated wastewater over many years, without proper management leads to accumulation of salts in soil profile (salinization), reduction in hydraulic conductivity of soil, waterlogging and it leads yield reduction. A subsurface drainage system field experiment (Sunflower) was conducted in split plot design to study the effect of subsurface drainage system and influence of amendments on saline alkali soil reclamation. The experiment consists of 2 main plots (drained field and undrained field) and seven subplots with different amendments. Among the drainage system and amendments, the amendments application in drained field improved the soil quality parameters by reducing soil pH, EC and ESP over undrained field. The application of FYM along with gypsum requirement and recommended dose of fertilizer reduced soil pH, EC and ESP. The application of FYM reduced the ESP 46.42 per cent in drained field over undrained control. The drainage system reduced the soil salinity and improved the soil quality parameters.
