    The study was done to assess the overhead irrigation system performance of dragline sprinklers at Finchaa, Eastbank sugar estate irrigation scheme using water distribution uniformity indicators, sprinkler discharge efficiency and variation of system discharge and operating pressure. The measurements of sprinklers water distribution uniformity were made for overlapped sprinklers at recommended spacing of 18 m × 18 m at head, middle and tail end of lateral lines for selected field at different locations of the command area. The estimated values of uniformity coefficients (CUc) and distribution uniformity (DU) along the laterals from head to tail ends varied from 71.8 to 82.8% and 66.6 to 74.3% respectively. The water distribution uniformity decreased from head end to the tail end of the lateral lines and was not satisfactory at middle and tail ends of the laterals. The sprinklers d.. Read More»
