Abstract: Subsurface drainage improves the productivity of poorly drained soils by lowering the water table, providing greater soil aeration, improving root zone soil salinity and enhancing the crop yield. Therefore, the study was conducted to check the impact of subsurface drainage system on soil quality parameters, land and crop performance in the UKP command Area, Karnataka. The study area is located at Malla-Buzurg (B) village in Shorapur taluk, Yadgiri district within 16°43’34.18” N to 16°44’10.52” N and longitude of 76°34’10.02” E to 76°34’43.13” E at an elevation of 458 m above the mean sea level. The mean pHs values before sowing and after harvesting ranged from 8.20 to 8.75 and 8.32 to 8.94 respectively. The mean ECe and ESP values before sowing ranged from 8.57 to 20.08 dS m-1 and 19.70 to 24.14 and after harvesting of the crops results obtained were in range of 8.52 to 19.59 dS m-1 and 19.36 to 23.36 respectively. A glance at results reveals that pH and K+ was observed to be increased due to sodic nature of soil and excess application of the fertilizer. ESP was noticed to be reduced as compared to pre-sowing conditions, gypsum needed to be applied in required amount in order to turn the soil from sodicity to saline or non-saline soils. Finally, the cropping intensity and crop yield was observed to be increased by 146.20 and 47.68 per cent respectively as compare to pre drainage condition
