What is drip ? It is an irrigation method that saves water and fertilizer by allowing water to drip slowly to

the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters.

It is done through narrow tubes that deliver water directly to the base of the plant.

HISTORY OF THE DRIP IRRIGATION

• Modern drip irrigation began its development in Germany in 1860

• The usage of plastic to hold and distribute water in drip irrigation was later developed in Australia(1920) by Hannis Thill.

• Usage of a plastic emitter in drip irrigation was developed in Israel by Simcha Blass and his son Yeshayahu

• The first experimental system of this type was established in 1959 by Blass who partnered later (1964) with Kibbutz Hatzerim to create an irrigation company called Netafim.

• Together they developed and patented the first practical surface drip irrigation emitter.

Advantages of Drip Irrigation:

1. Maximum use of available water.2. No water being available to weeds. 3. Maximum crop yield. 4. High efficiency in the use of fertilizers.5. Less weed growth and restricts population of potential hosts. 6. Low labour and relatively low operation cost. 7. No soil erosion.8. Improved infiltration in soil of low intake. 9. Ready adjustment to sophisticated automatic control.10. No runoff of fertilizers into ground water. 11. Less evaporation losses of water as compared to surface irrigation. 12. Improves seed germination. 13. Decreased to tillage operations.

Disadvantages of Drip Irrigation

• In spite of the fact that drip irrigation has so many potential benefits , they’re a certain limitation also, there are as follow:• 1. Sensitivity to clogging

2. Moisture distribution problem3. Salinity hazards4. High cost compared to furrow. 5. High skill is required for design, install and operation.

Awareness in farmer

• For a speedy growth of micro-irrigation, a special package scheme can be introduced where priority can be given in providing bank loan for digging wells and electricity connection (pump-set) for those farmers who are ready to adopt micro irrigation for cultivating any crop• Except in Maharashtra and Andhra Pradesh, no other state has

separate state sponsored schemes for promoting micro-irrigation as of today. All other states have been operating schemes mainly with the support of Central government (which is known as centrally sponsored schemes), which started in 1990-91.• Training facilities for farmers are essential to increase the adoption of

micro irrigation

Issues and challenges

• A survey of landscape professionals and homeowners had "drip irrigation"as the highest maintenance of irrigation systems; it requires constant monitoring.• Most maintenance people are not familiar with drip system repair, maintenance

or even simple scheduling – there are too many different systems. And less familiar are home-owners.• For most efficient use, systems require pressure regulation (usually pressure

reduction); a bit of information rarely shared at purchase.• Often shoddy products. (There are quality products available but that'snot usually what people are looking for with "drip" systems – usually people are seeking a cheaper irrigation solution).Provides no cooling effect for plants during hot spells.

Government policy and subsidy• Micro irrigation scheme (Drip system) is Centrally Sponsored Scheme

under which out of the total cost of the System, 40% will be borne by the Central Government, 10% by the State Government and the remaining 50% will be borne by the beneficiary either through his/her own resources or soft loan from financial
