A field experiment was conducted to investigate the effect of drip and surface furrow irrigation on growth, yield and water use efficiency of groundnut to at College Farm, Rajendranagar. The experiment consisted of six irrigation treatments i.e., I1= 0.4 Epan, I2= 0.6 Epan, I3= 0.8 Epan, I4= 1.0 Epan, I5= 1.2 Epan through drip system and I1= Surface furrow irrigation at 1.0 IW/CPE ratio replicated four times. The results revealed that among drip irrigation levels, plant growth traits, yield attributing characters and yield of groundnut increased significantly at each higher levels of drip irrigation from 0.4 Epan (1234 kg ha-1) up to 1.0 Epan (4005 kg ha-1) and further increasing irrigation level to 1.2 Epan resulted in yield reduction (3801 kg ha-1). However, economic yield with optimum water use was obtained when irrigation was scheduled at 0.8 Epan (3765 kg ha-1). Water use efficiency was found to be higher when suboptimal drip irrigation scheduled at 0.8 Epan (21.0 kg ha mm-1) compared to rest of the schedules. Hence, this study reveals that maximum yield can be achieved with minimum quantity of water application through appropriate irrigation method (drip method) compared to surface irrigation under scarce situation.
