Abstract: Land and water are the basic inputs for agricultural development of a country；adoption drip irrigation in potato cultivation is to overcome the problems of timely rainfall，scarcity of water and land leveling.This study critically assessed the influence of frequent availability of water i.e.drip irrigation compared over furrow irrigation on growth，yield and water use efficiency.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（hm2·mm））in terms of yield per ha-mm of water applied and highest cost benefit 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（hm2·mm））in terms of yield and B∶C ratio is 1.91.This research clearly indicates that economic use of water by drip method of irrigation play a key important role in managing water in high water sensitive crops like potato and hence the water saved in drip system of irrigation can be profitably used for increasing area of potato cultivation.
