Drip irrigation is an extremely efficient method of delivering water to a plant. The concept is quite simple delivers the water slowly, drip by drip, at a precise rate directly to the root zone. This keeps the root zone evenly moist and encourages deeper root growth. Drip irrigation is a method of applying slow, steady, and precise amounts of water and nutrients to specific areas of trees, vines, ground covers, potted plants. Emitters made of short lengths (20 cm) of microtube provide excellent uniformity in water distribution at low pressures (as good as any on-line emitters). The water filtration required for microtube emitters is much simpler than what is required for typical on-line emitters and when a microtube emitters become clogged it can usually be cleaned or inexpensively replaced, which is impossible to do with on-line emitters. An experiment was conducted and the discharge at various operating pressure was measured that is from 0.25 kg/cm2-1.25 kg/cm2. The obtained experimental results indicated that maximum discharge has been observed at first two drippers and minimum at last drippers. As the distance of drippers from the lateral head increases, discharge of dripper decreases.
