Drip irrigation The drip irrigation can be defined as slow application of water near or into the plant root zone at a rate equivalent to consumptive use by surface or sub-surface emitters. Drip irrigation basically consists of mainline, submain, laterals, valves, dripper or emitters, riser valves and filters. Low density polyethylene pipes are laid along the plant or tree rows with outlets or dripper inserted at appropriate intervals. These are designed to supply water at the desired rate (1-10 litres/hr) directly to the soil. Low pressure ranging from 0.35 to 2 kg/cm² are sufficient. The performance of drip irrigation on horticultural and other high value row crops has been very encouraging.
Sprinkler irrigation Sprinkler is an irrigation system that sprinkles water in a manner similar to rainfall.
It is suitable in undulated topography, but its investment and operating costs are higher. Water is conveyed through a network of pipes, called mains and laterals under high pressure and is forced through nozzles of small diameter. Water is applied once in 2-4 days period.
