Per Drop More Crop 2026: Can Micro-Irrigation Ease India’s Farm Water Crisis?
India’s farm-water problem is not simply that the country does not have enough water. A large part of the problem is how efficiently available water is used.
Agriculture accounts for more than 80% of India’s available water use, yet only about half of the country’s net sown area has access to irrigation. At the same time, groundwater levels are under pressure in several major farming regions.
Against this background, the government is trying to expand micro-irrigation through the Per Drop More Crop (PDMC) scheme.
A fresh government update released on 29 August 2026 shows that more than 115 lakh hectares have now been covered under micro-irrigation through PDMC. This is equivalent to around 8.11% of India’s net sown area.
During 2025–26 alone, around 12.30 lakh farmers benefited from the programme, and nearly 20% of the beneficiaries were women.
The numbers show progress, but they also underline the scale of the challenge. If India wants agriculture to remain productive in an era of groundwater stress and changing rainfall patterns, simply creating more irrigation infrastructure will not be enough. Farms will also have to use water much more carefully.
What is Per Drop More Crop?
Per Drop More Crop is a Centrally Sponsored Scheme that promotes efficient use of water at the farm level.
Its main focus is on two forms of micro-irrigation:
- drip irrigation
- sprinkler irrigation
The idea behind both is straightforward: instead of flooding an entire field with water, supply only the amount of water the crop actually needs.
PDMC was implemented as part of the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) from 2015–16 to 2021–22.
Since 2022–23, it has been implemented under the Pradhan Mantri Rashtriya Krishi Vikas Yojana (PM-RKVY).
This shift is worth remembering for Prelims because older material may still describe PDMC simply as a component of PMKSY.
Why does India need micro-irrigation?
Traditional irrigation often involves releasing large amounts of water into fields.
Some of this water reaches crops. But a considerable amount can be lost through:
- evaporation,
- runoff,
- seepage and
- over-irrigation.
In groundwater-dependent areas, inefficient irrigation also means more pumping, which increases both water extraction and electricity use.
Micro-irrigation tries to reduce this wastage.
Instead of asking only:
How can we bring more water to farms?
the policy asks another equally important question:
How can farmers produce more with the water they already have?
That is where the phrase “Per Drop More Crop” comes from.
Drip irrigation: water directly to the roots
In a drip-irrigation system, water moves through pipes and is released slowly through small emitters close to the root zone of individual plants.
This means water is concentrated where the crop actually needs it.
Drip irrigation is especially useful for crops such as:
- fruits,
- vegetables,
- sugarcane and
- other widely spaced horticultural crops.
Because the entire field is not flooded, water losses can be considerably lower.
It also allows farmers to combine irrigation with fertiliser application.
This is known as fertigation.
In fertigation, fertilisers are dissolved in irrigation water and supplied directly near the roots. This can improve nutrient-use efficiency while reducing wastage.
How is sprinkler irrigation different?
Sprinkler irrigation works more like artificial rainfall.
Water is pushed through pipes under pressure and sprayed over crops through nozzles.
It is useful for crops where plants are grown relatively close together, including many:
- cereals,
- pulses,
- vegetables,
- spices and
- field crops.
So the basic distinction is easy to remember:
Drip irrigation → water near the root zone
Sprinkler irrigation → water sprayed over the field like rainfall
The best system depends on the crop, soil, terrain, water availability and cost.
How much support do farmers receive?
The cost of installing micro-irrigation equipment can be a major barrier, especially for smaller farmers.
PDMC therefore provides financial assistance.
Small and marginal farmers
They can receive 55% financial assistance for the installation of micro-irrigation systems.
Other farmers
They can receive 45% assistance.
The support is available for up to five hectares per beneficiary.
Some state governments provide additional assistance from their own budgets, meaning the farmer’s actual contribution can be even lower in certain states.
According to the 29 August government update, the Centre released ₹8,123.24 crore in assistance for PDMC over the last three years.
Farmers can also become eligible for assistance again on the same land after seven years, subject to scheme conditions.
What has PDMC achieved so far?
The latest numbers show that PDMC coverage has continued to expand.
As of July 2026:
- more than 115 lakh hectares had been brought under micro-irrigation;
- this represented about 8.11% of India’s net sown area.
During 2025–26:
- 12.30 lakh farmers benefited;
- roughly 20% of beneficiaries were women.
The states with some of the largest areas covered under the programme included:
- Maharashtra,
- Karnataka,
- Andhra Pradesh,
- Tamil Nadu,
- Gujarat and
- Rajasthan.
Several of these states either face recurring water stress or have large areas under crops that can benefit significantly from micro-irrigation.
Does micro-irrigation actually save water?
Evidence suggests that it can, although the results vary by crop and region.
Government-cited studies have reported:
- 20–48% water savings
- 10–17% energy savings
- 30–40% reduction in labour costs
- 11–19% fertiliser savings
- 20–38% improvement in crop yields
A NITI Aayog assessment also reported improvements in water-use efficiency ranging from 30% to 70%, along with increases in farmers’ income in the areas studied.
These figures should not be treated as guaranteed results for every farmer. The actual benefit depends on factors such as crop choice, maintenance, local climate and how well the irrigation system is operated.
But they show why micro-irrigation is increasingly seen as an important part of water-efficient farming.
A farmer-level example
The latest government backgrounder gives the example of a farmer from Palnadu in Andhra Pradesh who shifted from conventional flood irrigation to drip irrigation in a two-acre acid-lime orchard.
According to the case study, yield increased from 90 quintals to 105 quintals per acre, while cultivation costs fell from around ₹3 lakh to ₹2.4 lakh.
His reported net income rose from ₹1.5 lakh to ₹2.85 lakh.
One individual case cannot represent all of Indian agriculture, but it illustrates why farmers may be interested in the technology: the benefit is not merely saving water. Proper micro-irrigation can also reduce input costs and improve productivity.
The groundwater problem makes this more urgent
India’s agricultural success has been closely linked with groundwater.
Tube wells and bore wells allowed farmers to irrigate crops even when rainfall was uncertain.
But this model has created serious stress in several regions.
When electricity is cheap or heavily subsidised and water is pumped without effective limits, farmers have little immediate incentive to reduce groundwater extraction.
Water-intensive crops grown in dry areas can make the problem worse.
Micro-irrigation cannot solve groundwater depletion on its own.
A farmer may save water per hectare but use the saved water to expand cultivation, which can reduce the overall conservation benefit.
That is why micro-irrigation has to be combined with:
- sensible crop choices,
- groundwater regulation,
- water budgeting,
- rainwater harvesting and
- better electricity and irrigation policy.
For UPSC Mains, this is an important point: improving irrigation efficiency is necessary, but efficiency alone does not guarantee sustainable water use.
New flexibility for states
One of the more interesting changes under PDMC is greater flexibility for states and Union Territories to support small-scale water storage and conservation projects.
These can include:
- farm ponds,
- diggis or water-storage tanks and
- water-harvesting structures.
Earlier, expenditure under these “Other Interventions” was capped at:
- 20% of the allocation for general states and UTs;
- 40% for the North-East, Himalayan states, Jammu & Kashmir and Ladakh.
The revised framework allows states and UTs to go beyond these limits where local conditions require it.
This change makes sense because micro-irrigation equipment is useful only when farmers have a reasonably reliable water source.
A drip system cannot solve the problem if there is no water available to feed it.
The policy is therefore moving towards combining:
water conservation + water storage + efficient irrigation
rather than treating them as completely separate issues.
Why PM-RKVY matters here
Since 2022–23, PDMC has been implemented under PM-RKVY.
Rashtriya Krishi Vikas Yojana was originally launched in 2007–08 and was restructured as Pradhan Mantri Rashtriya Krishi Vikas Yojana in October 2024.
The restructured programme acts as an umbrella for several agricultural interventions and gives states more flexibility to shift funds between components according to local requirements.
This is important in agriculture because the same policy cannot always work equally well across India.
The irrigation needs of Rajasthan are different from those of Assam.
A horticulture-growing region may require a different micro-irrigation strategy from a rice-dominated area.
Greater state flexibility therefore fits the federal nature of agricultural policy.
Micro-irrigation and climate change
Climate change makes efficient irrigation even more important.
Indian agriculture remains heavily influenced by the monsoon.
Changes in rainfall can appear in several forms:
- delayed rainfall,
- long dry spells,
- unusually heavy downpours,
- shifting monsoon patterns and
- more frequent heat stress.
Even when total seasonal rainfall appears normal, its timing may not match crop requirements.
Micro-irrigation cannot create water where none exists, but it can allow farmers to use limited stored or groundwater supplies more carefully during periods of stress.
This makes it part of the wider idea of climate-resilient agriculture.
Can it reduce the cost of farming?
Potentially, yes.
Water and fertilisers are two major inputs in agriculture.
If drip irrigation and fertigation reduce their use without lowering output, the farmer’s cost per unit of production can fall.
There may also be savings in:
- pumping energy,
- labour,
- weed control and
- fertiliser application.
But there is an upfront cost.
Pipes, filters, pumps and emitters require investment and maintenance. Equipment can become clogged or damaged, and farmers need technical knowledge to use the system properly.
Subsidy alone is therefore not enough.
Farmers also need:
- reliable after-sales service,
- quality equipment,
- technical training and
- timely repair facilities.
Why is adoption still limited?
The 115 lakh hectares covered through PDMC is significant, but it is still only around 8.11% of India’s net sown area.
There are several reasons why micro-irrigation has not spread equally across the country.
High initial cost
Even after subsidies, smaller farmers may hesitate to invest.
Fragmented landholdings
Very small and scattered plots can make installation less attractive.
Crop patterns
Some crops and farming systems are easier to adapt to micro-irrigation than others.
Maintenance
Filters, pipes and emitters require regular upkeep.
Delays in subsidy
Slow reimbursement can discourage farmers.
Water and electricity pricing
Where groundwater and electricity are effectively available at very low cost, farmers may have less financial incentive to save water.
Awareness
Some farmers may not have enough information about which system is suitable for their crop.
These practical problems matter as much as the overall budget allocation.
India’s larger micro-irrigation target
The government has set a target of bringing an additional 100 lakh hectares under micro-irrigation during 2025–26 to 2029–30.
That requires coverage of roughly 20 lakh hectares every year.
Meeting this target will require much faster adoption than simply continuing with business as usual.
The challenge will be to ensure that expansion is not driven only by subsidy numbers but by systems that farmers continue using effectively after installation.
What should India do next?
India needs to move beyond seeing micro-irrigation simply as an equipment-distribution scheme.
A stronger approach would combine several policies.
Match crops with local water availability
Water-intensive crops should not be encouraged indiscriminately in severely water-stressed regions.
Link irrigation with water harvesting
Farm ponds, check dams and local storage can make micro-irrigation more reliable.
Strengthen farmer training
A poorly maintained drip system cannot deliver its expected benefits.
Improve monitoring
Policy should measure actual water savings and continued use, not only the number of systems installed.
Promote fertigation carefully
Precision use of fertilisers can lower costs and reduce nutrient losses.
Focus on small farmers
Smaller holdings may require community systems, farmer groups or shared infrastructure.
Use technology
Sensors, soil-moisture information and automated irrigation can gradually make water application even more precise.
The aim should not simply be more irrigation, but smarter irrigation.

Drip: water is supplied close to the roots through emitters.
Sprinkler: water is sprayed over crops under pressure, similar to rainfall.
UPSC/State PCS Relevance
For GS Paper III, this topic connects directly with:
- irrigation,
- groundwater,
- agricultural productivity,
- climate-resilient agriculture,
- government farm schemes,
- resource-use efficiency and
- sustainable agriculture.
It can also be linked with questions on:
- water crisis,
- cropping patterns,
- agricultural subsidies and
- climate adaptation.
Possible UPSC Mains Question
“Micro-irrigation can improve water-use efficiency in Indian agriculture, but technology alone cannot solve the country’s groundwater crisis.” Discuss.
A good answer should first explain the importance of agriculture in India’s water consumption and the working of drip and sprinkler irrigation.
Then discuss the benefits:
- water savings,
- higher productivity,
- fertigation,
- lower input costs and
- climate resilience.
The second half should examine the limitations:
- unsuitable cropping patterns,
- subsidised electricity,
- excessive groundwater extraction,
- high installation costs,
- fragmented holdings and
- maintenance problems.
The conclusion should argue for an integrated approach combining micro-irrigation, crop diversification, groundwater management and local water conservation.
Conclusion
India cannot deal with agricultural water stress simply by digging deeper wells or building more irrigation channels.
The country also has to make better use of every unit of water that already reaches the farm.
That is where Per Drop More Crop has an important role.
The expansion to more than 115 lakh hectares shows that micro-irrigation is no longer a small experiment. But the fact that this represents only about 8.11% of the net sown area shows how much room for expansion remains.
The real success of the programme will not be measured by the number of drip pipes installed. It will be measured by whether farmers are able to grow reliable crops with less water, lower costs and greater resilience to an increasingly uncertain climate.
