A study was carried out to evaluate applicability of four different pedotransfer functions (Rosetta, Jabro, Puckett
and Campbell) in estimating saturated hydraulic conductivity (Ks) of soils from Shirala Nemane watershed
with geographical area of 22,400 ha. in Buldhana district of Maharashtra state. Eighty seven sampling points were marked at a grid of 2 km x 2 km using Global Positioning System. Soil samples were collected from each sampling point at a depth of 0-30 cm. The measured and estimated Ks were compared with one to one correspondence using statistical indices such as root mean square error (RMSE), mean error (ME), mean absolute error (MAE), degree of agreement (d) and coefficient of determination (R2). The lowest RMSE value (0.6921 cm/hr) and highest R2 value (0.0702) was observed in estimation of Ks using generic pedotransfer function- Rosetta. Prediction of Ks using Rosetta had lower errors than Jabro, Puckett and Campbell parametric pedotransfer function.
