Drip irrigation technique is very useful for the row planted crops like vegetables and irrigating the crops of hill sides and rolling grounds. In vegetables, drip irrigation is known to save 25–70% of water depending on soil, climate, crop and variety. The irrigation efficiency of drip system is very high (85–90%). Experiments conducted at ICAR- IIVR, Varanasi indicated that surface drip irrigation can save about 55–62%, 34%, 31% and 38% water, respectively in tomato, cucumber, okra and broccoli. Drip irrigation, if combined with plastic mulch, can further save 15–35% more water with improved water use efficiency. Mulching experiments revealed that in tomato, about 11% and 15% water savings were achieved with use of black polythene and transparent polythene mulch, but when black polythene mulch was used in combination of raised bed planting or drip irrigation, 46% and 66% water savings, respectively were achieved as compared to absolute control. On the other hand, organic mulches such as straw, dry grass, plant residues, etc are also equally effective to conserve soil moisture thereby saving of water, besides improving physico-chemical properties of soil.
