Drip Irrigation Cost Per Acre in India — and What the Subsidy Really Pays

Two numbers decide what drip irrigation costs you, and only one of them is the price your dealer quotes.

The second number is the notified unit cost — a schedule of rupee figures the Government of India publishes for every combination of crop spacing and plot size. Your subsidy is 55% of that figure if you are a small or marginal farmer, and 45% if you are not. It is not a percentage of your quotation, and no amount of negotiating with the dealer changes it.

For roughly one acre — the guidelines price a 0.4 hectare plot, which is 0.988 of an acre — the notified cost runs from ₹18,009 for widely spaced orchard crops to ₹57,241 for closely spaced vegetables. So a small or marginal farmer putting drip on an acre of vegetables is looking at about ₹31,483 of assistance, and a larger farmer about ₹25,758.

That is the whole calculation. Everything else on this page is about the gap between it and what you will really pay.

This is the government's own table, for a 0.4 hectare plot — near enough an acre for planning. Spacing means row-to-row × plant-to-plant. Find the row that matches your crop, and the subsidy columns show what you can expect back.

Two things to read carefully.

Closer spacing costs more, not less. More rows per acre means more lateral pipe and more emitters. An acre of onions carries roughly three times the notified cost of an acre of mango. Growers who budget from a neighbour's orchard quote are usually short by a wide margin. The row spacings in the middle of the table are where most of the scheme's money goes — they are the spacings used for sugarcane and cotton, the water-hungry field crops micro-irrigation was largely built for.

These are the general-state figures. Bihar, Chhattisgarh, Jharkhand, Odisha, Uttar Pradesh, West Bengal, Goa, Punjab and the Union Territories are classed as low-penetration states and get 15% higher notified costs. Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Sikkim, Jammu & Kashmir, Himachal Pradesh, Uttarakhand and Ladakh get 25% higher. In Uttar Pradesh, that acre of vegetables is notified at ₹65,827 rather than ₹57,241 — about ₹4,700 more in a small farmer's hand.

This is the single most common misunderstanding about drip subsidy, and it is worth being blunt about.

The guidelines say the subsidy payment is limited to the notified unit costs. If a dealer quotes ₹75,000 for an acre of vegetable drip and the notified cost is ₹57,241, a small or marginal farmer receives ₹31,483 — not 55% of ₹75,000. The farmer's own share is ₹43,517, which is 58% of the bill, not 45%.

The gap opens for ordinary reasons. Quotations often include a pump, a filtration unit sized above the standard list, extra mainline because the water source is far from the plot, or a higher-grade emitter. The notified cost assumes the water source sits at the corner of the plot and prices a standard component list.

The practical move is simple: ask the dealer to quote against the notified unit cost for your spacing and plot size, and to itemise anything above it separately. A dealer registered under the scheme will know the number. If the quotation cannot be broken down that way, that is worth knowing before you sign, not after the subsidy is calculated.

Farmers in Maharashtra, Gujarat, Karnataka, Andhra Pradesh and Tamil Nadu routinely report far higher assistance than the 45–55% above. They are not misremembering, and the central rate has not changed.

What they are getting is a state top-up paid on top of the central share. The mechanism is the Micro Irrigation Fund, set up with NABARD in 2018-19 with a ₹5,000 crore corpus and doubled by another ₹5,000 crore approved by the Union Cabinet in October 2024. States borrow from it at 2% below NABARD's cost of funds and use the money to lift the subsidy above the central floor.

Two consequences follow. First, the fund is accessed by state governments, not by farmers — there is no MIF form for an individual to fill in, and anyone offering to get you MIF money directly is describing something that does not exist. Second, the size of your subsidy depends heavily on which state you farm in. The government's own assessment is that western and southern states use a substantial share of the PDMC allocation while the Indo-Gangetic plain, eastern and north-eastern states do not — which is precisely why those states get the 15% and 25% higher notified costs described above.

One more piece of vocabulary worth having straight. The scheme is still widely called PMKSY, but Per Drop More Crop moved out of Pradhan Mantri Krishi Sinchayee Yojana in 2022-23 and now runs under the Pradhan Mantri Rashtriya Krishi Vikas Yojana (PM-RKVY). Pages still quoting PMKSY cost norms are quoting a schedule that has since been revised.

These come straight from the operational guidelines, and each one turns down applications every season.

A 5 hectare ceiling per beneficiary. Drip and sprinkler combined. If you run more than about 12 acres, the balance is on you.

Seven years before you can claim again on the same land. The guidelines put the projected life of a micro-irrigation system at seven years, and subsidy on that plot restarts only after it. Replacing a system early is at your own cost.

Only a new system from a registered manufacturer. Equipment that has drawn a subsidy under any government scheme before is not eligible, components must be BIS marked, and manufacturers are registered for five-year terms with penalty provisions for violations.

A fertigation device is mandatory. A venturi injector or fertiliser tank must be part of the system — and the subsidy covers it, so this is a requirement that costs you nothing extra.

You cannot split one plot into pockets. Farms in different locations with different water sources can each be claimed, but subdividing a single location into small parcels of the same crop to multiply the claim is expressly barred. Under intercropping, assistance is paid for one crop of your choosing.

Three years of free after-sales service. The installing company is required to provide it from the date of installation. It is a term of the scheme, not a favour, and worth putting in writing at the time of purchase.

Applications are made through your state's agriculture or horticulture department portal, not through a central website — MahaDBT in Maharashtra, GGRC in Gujarat, the K-Kisan portal in Karnataka, RajKisan in Rajasthan, and their equivalents elsewhere. The national PDMC portal carries the scheme documents and links out to each state. Subsidy is paid by direct benefit transfer after the system is installed and verified, so you fund the purchase first and are reimbursed.

On the return: the government's stated case is that micro-irrigation delivers water savings of up to 40% against flood irrigation, alongside lower fertiliser, labour and input costs. Between FY16 and FY25 the scheme released ₹21,968.75 crore to states and covered 95.58 lakh hectares, and the target now runs to 109 lakh hectares by 2029-30. Against an assessed national potential of 69.6 million hectares, the country has covered under a seventh of what could be done. For context on what it is replacing: tube wells and other wells supply about 60% of India's irrigated area, so most of the water drip saves is groundwater a farmer is pumping at their own cost.

Whether it pays on your plot is a narrower question than any of that. Drip earns its cost back fastest on high-value, closely spaced, water-hungry crops — which is exactly where the notified cost is highest. On a widely spaced orchard the system is cheap but the water saving is smaller. Work it out against your own crop's water bill and yield, not against a national average.
