Demands of water are ever increasing due to growing population and related developmental needs in agriculture and other sectors. Adoption of drip irrigation in potato cultivation is to overcome the problems of scarcity of water and erratic rainfall. Field experiment was conducted at the Department of Agricultural Engineering, GKVK Campus of the University of Agricultural Sciences, Bangalore. The outcome of the research shows once in two days irrigation given through drip system recorded significantly higher returns as compared to every three, fourth and fifth day irrigation given through drip system. Highest water use efficiency (56.24 kg ha-1mm-1) in terms of yield per ha-mm of water applied and Highest benefit cost ratio (B: C) of 2.33 was recorded in the treatment irrigated every alternative day through drip system, closely followed by 2.25 in the treatment irrigated once in three days by drip irrigation system as compared to conventional furrow irrigation system (14.16 kg ha-1mm-1) in terms of yield and B:C ratio is 1.91. This research clearly indicates that economic use of water by solar operated drip method of irrigation play a key important role in managing water in high water sensitive crops like potato.
