Drip Irrigation System: A Water and Nutrient Conservation Approach to Sustainable Crop Production
Abstract
Drip irrigation system is a most efficient and modern technique of irrigation, this method is used in those area where there is a scarcity of water, In this technique generally water and nutrient are allowed to deliver directly to the root zone by controlling the pressurised water through valves of the P.V.C (polyvinyl chloride) drip pipes in such a way that it systematically irrigate the whole field drop by drop directly to the root zone, and saves water up-to 70% as compare to flood irrigation method.

Introduction
Drip irrigation is a modern concept of irrigation in which generally water and nutrients are allowed directly reached to the roots zone drop by drop in the right amount. As the name implies drip irrigation which means irrigation is done by drops of water. It is also known trickle irrigation or a micro-irrigation system.
FIGURE 1: Drip Irrigation System In this modern era this modern facility of irrigation are generally adapted for irrigation because it is very effective and efficient method of irrigation, as it also have the potential to save enough amount of nutrients and water up-to 70%, by allowing water to deliver systematically directly to the root zone of the plants.
In drip irrigation system, specially designed P.V.C. or Polyvinyl hosepipes having a diameter 13-32 mm are generally used to install this modern irrigation system, through these pipes water are allowed to reach directly to the root zone drop by drop of the plants, and helps the plants to grow un-effectively and efficiently. The main objective of the drip irrigation is to place water directly into the root zone and minimize the evaporation rate.
Conclusion
: Drip irrigation system mainly used in dry-land areas, where there is a scarcity of rainfall and water, like arid and semi-arid region. To overcome this problem farmers have to adopt this modern irrigation technique in dry land areas and have to take a one step towards Drip irrigation system, as this system need limited amount of water to irrigate the whole field drop by drop and also have a potential to conserve 70% of water as compare to flood irrigation.
In my opinion this is the best method of irrigation for dry land areas, all arid and semiarid region farmers have to adopt this method of irrigation for the effective and sustainable production of crops and plants.
