A field experiment was conducted for seven years (1995-96 to 2002-03) to determine the water requirement of pomegranate (cv. Jyothi) in Vertisols through drip irrigation at the Water Management Research Centre, Belvatagi, Tq. Navalgund District, Dharwad, Karnataka, India. Treatments were combinations of four wetted areas (20, 40, 60 and 80% of spacing) and three pan fractions (0.25, 0.50 and 0.75) compared with surface irrigation. The irrigation water was applied once in two days based on daily pan evaporation readings. Surface irrigation was given at 0.6 IW:CPE [irrigation water:cumulative pan evaporation ratio]. The highest mean fruit yield of 17.88 kg/tree was obtained in the treatment with 80% wetted area and 0.75 pan fraction. Water applied per tree/day, water use efficiency and water saving over surface irrigation were in the range of 22-54 litres, 75-173 kg/ha-cm and 0-59%, respectively. The highest water use efficiency of 173 kg/ha cm was observed in 40% wetted area and 0.50 pan fraction with a saving of 39% water over surface irrigation. The gross income, cost of cultivation and benefit:cost ratios were in the range of Rs.19 800 to 88 200, Rs.18 700 to 23 740 and 0.06 to 2.72, respectively.
