Authors: Raju Jati, Bibudh Dhewaju, Ram Bahadur Rana
Drip irrigation is an easy and inexpensive irrigation method that reduces weed growth, insect pest and disease occurrence, and facilitate proper water management. Moreover, it can be used in all climates and on every soil and crop type. It is water efficient technology which allows water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubes, regulators and emitters. The narrow tubes deliver water directly to the base of the plant. It is the most efficient method of irrigation saving up to 50-90 percent water than the traditional one. Traditionally, when irrigation water was applied to the entire field, whether by sprinklers or by flood irrigation, there was significant loss of water.
