Where lot of talks regarding adoption of “Drip Irrigation” going on there seems a need of changing the earlier ways of yielding crops and making agriculture more productive and innovative. Drip irrigation systems (also called trickle) apply water directly to the root zone of the crop via small holes or emitters spaced along polyethylene pipe. Drip irrigation systems are able to precisely apply (control) water to the crop, potentially maintaining a high level of irrigation efficiency. In addition water losses are also minimised by not irrigating the whole field. Before adopting any newly launched technology it is very important for people to know how does it function, and how effective it is. Generally Drip Irrigation talks about water saving so we need to see to what range it would be useful to implement this newly launched technique.
Documented Range of Water Savings:-
Drip irrigation systems can potentially exceed irrigationapplication efficiency (AE) greater than 90% (Raine et al, 2000). Whilst performance is a function of design it is also highly sensitive to installation, maintenance and management aspects. In practice application efficiencies have been reported to vary from 30 to 90% (Shannon etal., 1996). Generally deep drainage losses are the greatest source of these volumetric inefficiencies. Deep drainage occurs as a result of excessive irrigation run times due to a lack of knowledge concerning the volume of water required to recharge the root zone. More commonly Raine et al. (2000) suggests other factors which contribute to deep drainage include the non uniformity of the application system. A survey of drip irrigation in the Australian cotton industryconducted by Raine et al. (2000) identified all growers using subsurface drip irrigation reported water savings compared to traditional surface. Water savings of 38% are reported although it was suggested that the water savings would be less where surface irrigation systems had been optimised. Where irrigators were seeking to maximise production (as opposed to water savings) average yield improvements of 2.7 bales / ha were achieved. For horticultural crops, Henderson (2003) reported 15% more marketable produce than sprinkler based systems with 10% less water use.
How to implement Drip Irrigation Technology
For the above mentioned details and reports proven we can definitely show our trust on this technique which talks about “per drop more profit” and “per drop per crop”. We can conclude that Drip Irrigation would be a successful implementation for indian farmers and they no more have to crave for god’s mercy for good climatic conditions. India being a major suffer in the field of agriculture is now getting ready to overcome from the losses which occurred to them because of bad climatic conditions, natural calamities, and outdated methods of agriculture. India getting diigitalized seems to gain the farmers trust as now they are finally doing something for that category of people who feed the nation.
