Field experiment was conducted for two years in Northern Dry zone of Karnataka to work out the water requirement of ber through drip irrigation.  Treatment combinations of wetted area (20,40,60 and 80%) and pan evaporation (25,50 and 75%) were compared with surface irrigation and rainfed control.  The mean fruit yield of ber was increased by 3.20 times with surface irrigation and 2.86 to 4.05 times under various drip irrigation treatments over rainfed control (8.0q/ha).  Scheduling  of irrigation through drip as per T3 (60%WA X 25% PE or 20% WA X 75% PE) was found optimum with significantly higher fruit yield (30.2 q/ha), saving in water (61.5 to 66.2%) over surface irrigation.  The highest water-use-efficiency (1.33 and 3.82 q/ha-cm) was also recorded in this treatment.  The main stem girth, canopy coverage and canopy volume of ber tree during its early growth stages were significantly influenced due to various water application rates through drip irrigation.
