This research work was conducted during rabi 1999-2000 on wheat at Phularwan research farm of Water and Power Development Authority located in Tehsil Bhalwal, District Sargodha, Pakistan, to evaluate the comparative performance of sprinkle and surface irrigation application methods in terms of water conservation, yield and salinity management. For sprinkle irrigation plot, water source was a dugwell with a very low recharge rate, 3.05 m diameter, total well depth of 6.25 m and water column of ~4.878 m. A raingun (PY1-30) operated with 12- and 10-mm nozzles was used to irrigate the field. The surface irrigation plot was irrigated using three strainers skimming well. Qualities of both water sources were almost the same. Similar treatments were applied to both plots. Effects of surface and sprinkle irrigation methods on wheat crop were determined. Salinity of both irrigation plots was found sustainable and uniform. Seasonal effects of salinity were more pronounced in topsoil. Sprinkle irrigation plot performed better than surface irrigation method in terms of water conservation and yield. Using sprinkle irrigation method, 68% of water was conserved and 17% increase in yield was obtained. Water use efficiency for sprinkle irrigation method and surface irrigation were 1.77 and 0.895 kg/m3, respectively. More financial benefits could be obtained from sprinkle irrigation system than surface irrigation system in terms of water conservation and increase in yield. However, the capital and operating costs are higher in sprinkle irrigation method than in surface irrigation method.
