Field experiments were conducted at Agricultural Research Station, Tamil Nadu Agricultural University, Bhavanisagar, Tamil Nadu, India to evaluate the irrigation systems for cost reduction in wide spaced sugarcane during 2000-2004. The results revealed that, drip irrigation at 60% PE with one lateral row-1 significantly recorded higher sugarcane yield of 164.8 t ha-1 with enhanced water use efficiency of 166.1 kg ha-1 mm-1 and highest net returns of ` 83,650 ha-1. Among the surface irrigation treatments, irrigation at 1.0 IW/CPE ratio recorded the maximum yield of 140.1 t ha-1 with a WUE of 90.7 kg ha-1 mm-1.
