Abstract: The study was carried out to check the performance of subsurface drainage system on soil quality parameters, land and crop performance in the UKP command Area, Karnataka. The study area is located between 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 lowest and highest of weekly overall weighted average discharge considering all the drains together has been observed that 0.18 mm d-1 in 10th week and 1.55 mm d-1 in 38th week respectively. Among the mains, the average discharge was 0.49, 0.43, 0.39, 1.19 and 1.30 mm d-1 in main I, II, III, IV and V respectively. Further, considering the whole area for the entire period of study, the overall weighted average discharge of the SSD system was found to be 0.76 mm d-1. The minimum and maximum salinity were observed in the month of September-2014 (i.e. 1.80 dS m-1) and December-2014 (5.67 dS m-1) in main drain outlet V and I respectively. The values of pooled mean salinity of the outlets were 3.99, 3.22, 4.09, 3.79, 4.20, 4.29 and 4.42 dS m-1 during August, September, October, November, December, January and February respectively, with the overall leachate mean salinity of the outlets was 4.04 dS m-1. The mean EC, SAR and RSC values observed to be 4.04, 7.95 and -24.56 respectively
