Adoption of high efficiency irrigation system for water management is the key component to ensure the food security in the world. The research was carried out at the experimental area of Water Management Research Center (WMRC) located at Post-Graduate Agricultural Research Station (PARS), University of Agriculture, Faisalabad. The drip irrigation system was installed on an area of about 5 hectares to evaluate uniformity of water application and wetting pattern of 60cm wide bed through three different treatments (T-1, T-II and T-III) Surface, Channel and Subsurface placement of drip laterals. Soil moisture content was recorded at start, middle and end of 67m long bed. Results shows that placement of drip in the channel gave better response of moisture content distribution than that the buried one and when placed openly on the bed. All three drip pipe placements (T1, T2, T3) differ significantly for location, positions, depths and their different interaction within the variables reported. Although, it was tried to put lateral in the center but analysis indicate that it was significant in case of open placed drip pipe whereas it was non-significant in the case of buried pipes or placed in channel. It is also important to mention that pipe placed in the channel was easy to handle, replace and to fold back than the buried one.
