Nano Urea and Nano DAP Subsidy in Rajasthan: Rates, Crops, How to Claim and What Studies Say

Yes, for this rabi season. As reported on 25 Oct 2026, Rajasthan is paying half of a fixed spray cost under its 2026-27 budget announcement, run through RKVY: Rs 1,000 per hectare for nano urea (cost fixed at Rs 2,000) and Rs 1,450 per hectare for nano DAP (cost fixed at Rs 2,900). That is about Rs 405 and Rs 587 per acre. Reported crops are wheat, barley, mustard, gram and cumin. You must be in a village cluster of at least 10 farmers, with 0.4 to 10 hectares sprayed under the supervision of the agriculture department, and the money comes by DBT after the field check. It is not a discount at the shop: you still buy the bottle at the printed price. Contact your Krishi Paryavekshak or the nearest agriculture office to join a cluster, because each district has a limited target. We could not read the official order, so confirm the rates there before you spray.

Is there a subsidy on nano urea and nano DAP in Rajasthan?

Yes. The Rajasthan government is paying farmers half of a fixed per-hectare spray cost for nano urea and nano DAP, as announced in the 2026-27 state budget and run under the Rashtriya Krishi Vikas Yojana (RKVY). The ABP News report of 25 October 2026 quotes a district agriculture officer and says the money goes straight to the farmer's bank account.

Two things are easy to miss. First, this is support for spraying inside supervised village demonstrations, so you cannot just buy a bottle and claim. Second, the numbers in news reports come from district officers. We looked for the department order or the RKVY guideline and could not find it online, so please treat every figure here as the reported figure and confirm it at your agriculture office.

How much is the nano urea and nano DAP subsidy per hectare and per acre?

Nano urea gets Rs 1,000 per hectare, which is half of a fixed spray cost of Rs 2,000. Nano DAP gets Rs 1,450 per hectare, half of Rs 2,900. In acres that is roughly Rs 405 and Rs 587. The farmer pays the other half. These are the figures reported by ABP News and BigHaat in the last week of October 2026.

The per-acre column is our own division (1 hectare is about 2.47 acres), not a number printed by the department. The reports do not say what exactly the fixed cost includes. A 500 ml bottle costs far less than the fixed amount, so we assume the norm also covers labour and sprayer cost, but that is our reading and is not confirmed. A farmer with 2 acres of wheat under nano urea can therefore expect a support of a little over Rs 800, not thousands of rupees.

Which crops and how much land are covered?

For rabi 2026-27 the reported crops are wheat, barley, mustard, gram (chana) and cumin (jeera). Land per farmer is from 0.4 hectare, about 1 acre, up to 10 hectares, about 25 acres. For kharif the same support was reported for bajra, maize, soybean and groundnut, but that last list comes from only one secondary source.

If you grow wheat, plan the spray along with your basal dose. Our wheat sowing planner lists the basal dose by zone, and the mustard fertiliser schedule covers the same for oilseed growers.

How does the cluster demonstration work?

The agriculture department groups at least 10 farmers of a village into a cluster. The spray is done in their fields under the watch of the agriculture supervisor, officials then inspect the sprayed fields, and the subsidy is released by DBT only after that check. The point is that neighbouring farmers can see the result for themselves.

• Target is limited. The ABP report quotes a district target of 680 hectares for nano urea and 476 hectares for nano DAP under RKVY. We do not know which district the officer spoke for, so this shows the scale of a district, not your district.
• Supervised spray. The spray should be done with the supervisor knowing the date. A spray you do alone before the cluster is registered may not be counted. Confirm this with the office.
• Field check before payment. Keep your bottle bill and take dated photographs of the spray as your own record. This is our practical advice, not a rule in the reports.

How to claim the nano urea and nano DAP subsidy in Rajasthan, step by step

We could not find an online application form for this scheme. The reports say to contact the village agriculture supervisor (Krishi Paryavekshak) or the nearest agriculture office, so the route is offline and through the cluster. Follow these steps and confirm each one locally.

1. Ask your Krishi Paryavekshak whether a nano urea or nano DAP cluster is planned in your village this rabi, and how much area is left in your district target.
2. Get listed in a cluster. At least 10 farmers are needed. If your village has not formed one, bring neighbours who have wheat, mustard or gram.
3. Confirm the area and the product. Ask how many hectares of your land will be counted (0.4 to 10) and whether nano urea, nano DAP or both will be sprayed.
4. Fix the spray date with the supervisor and keep the sprayer ready, battery, knapsack, tractor or drone. The reports say you arrange it yourself.
5. Keep the bank account active that is linked to your Aadhaar. Payment is by DBT.
6. Keep the purchase bill for the bottles and a photograph of the spray.
7. Wait for the field check and then follow up with the office if the money does not arrive.

The documents are not listed in the reports we read. Take your Aadhaar, bank passbook and land record details (jamabandi or khasra number) as a normal precaution, and ask the supervisor what is actually needed. If you are looking at other state schemes, our agriculture subsidy schemes guide and the schemes calendar help you track what is open.

What do nano urea and nano DAP cost compared with a bag of urea and DAP?

IFFCO's price list effective 1 January 2025 shows Nano Urea 500 ml at an MRP of Rs 225, Nano DAP 500 ml at Rs 600 and Nano DAP 250 ml at Rs 350. In the same list a 45 kg bag of subsidised urea is Rs 266.50 and a 50 kg bag of DAP is Rs 1,350. Prices on shop shelves and online sites can differ, so check the printed MRP.

On paper a bottle of nano urea is Rs 41.50 cheaper than a bag of urea, and a bottle of nano DAP is Rs 750 cheaper than a bag of DAP. The catch is that the bottle does not carry the same amount of nutrient as the bag. A 45 kg bag of urea carries about 20 kg of nitrogen, while a 500 ml bottle of nano urea carries about 20 g of nitrogen on the label (4 percent N by weight). The saving only holds if the plant gets the same benefit, and that is exactly what the studies below question. Rajasthan's own support (Rs 1,000 or Rs 1,450 per hectare) is for the spray, and does not change these prices. We found no central subsidy notice for nano fertilisers, and the IFFCO list shows them as a separate item from the subsidised fertilisers (VERIFY).

If DAP is short in your area, nano DAP is one of several options. Our DAP alternatives comparison puts it next to SSP and NPK 12:32:16 with plain costs.

How to use nano urea: dose per acre, number of sprays and timing

IFFCO's application guide says to mix 2 to 4 ml of nano urea in one litre of water and spray on the leaves at active growth stages. The label plan is two foliar sprays: the first at active tillering or branching, about 30 to 35 days after germination, and the second 20 to 25 days later, before flowering. A 500 ml bottle is generally used for about one acre.

Spray only on green, growing leaves. Nano urea does not work on soil and does not replace the basal dose. For nano DAP, the IFFCO line seen in search results is a seed treatment of 5 ml per kg of seed or 5 ml per litre for seedlings; the foliar dose for each crop should be taken from the bottle label (VERIFY). Do a small jar test before mixing with any other spray, and follow the sprayer maker's guide for nozzle and pressure. If you plan to use a drone, read the drone subsidy and Namo Drone Didi guide first, since drone spraying has its own rules.

Do not guess what your field lacks. Wheat that turns yellow after the first irrigation may need zinc, sulphur or manganese rather than another urea spray, as our wheat yellowing post explains, and a soil health card reading tells you the base level before you spend.

Does nano urea really work? What government trials and research say

The evidence is mixed. A government summary of ICAR and state university trials says nano urea with the full recommended basal dose can give comparable yield and 3 to 8 percent gain, while cutting urea use by 25 to 50 percent. But the Punjab Agricultural University found lower yield and lower grain nitrogen in a two-year rice and wheat study. Both are on record.

What can a Rajasthan farmer take from this? Nano spray looks safest as an add-on to a full basal dose, which is how the scheme is designed (one spray on top of your normal fertiliser). Cutting the soil dose heavily because of the bottle is where the doubts are strongest. Wheat is also grown in Punjab under very high fertiliser rates and irrigation, so the Punjab result may not carry over one-to-one to a dry Rajasthan field. That is a reason for local trials, not a reason to dismiss the study. Cluster demonstrations are meant to produce exactly that local evidence.

What are the disadvantages of nano urea, and what should a farmer watch for?

The main concerns raised in the sources are lower yield and grain protein when soil nitrogen is cut too far, extra spray labour and cost, uncertain results across soils, and sales pressure at the shop. None of these is a reason by itself to refuse the scheme, but they are reasons to keep your basal dose and test on part of your field first.

• Do not cut the base dose to save money. PAU and PIB both point to problems at high substitution, especially in poor soils.
• Check your own field. Keep one strip or a few rows without the spray, so you can compare yield at harvest. This costs nothing.
• Spray labour and equipment. A foliar spray needs a clean sprayer, a calm day and timing. The scheme does not pay for the sprayer.
• Quality of the bottle. Buy only from a licensed dealer, check the batch number, seal and expiry. Our post on how to identify fake pesticides and fertilisers lists the checks.
• Soil health is bigger than one bottle. Low organic carbon, pH problems and missing zinc or sulphur limit any fertiliser, nano or not.

Can a dealer force you to buy nano urea with urea or DAP?

No. Union agriculture minister Shivraj Singh Chouhan wrote to chief ministers in July 2025 that it is illegal to force farmers to buy other products by tagging them with conventional fertiliser bags, and asked states to stop forced tagging of nano fertilisers and biostimulants. The Hindustan Times report of 21 July 2025 carries the quote.

The complaint is widely reported: BusinessLine (31 Oct 2023), The Times of India Jaipur (13 Oct 2022) and The Indian Express (16 Oct 2025, Punjab) have all run stories on farmers saying dealers refuse a urea or DAP bag unless they also take a nano bottle (we read these as search-result headlines only). Our own post on the DAP and urea shortage covers the tagging debate during this season's shortage. If you face it:

• Ask for a written bill for exactly what you bought. Do not accept a bill with items you did not ask for.
• Report to the block or district agriculture officer in writing. Fertiliser dealers work under licence and a complaint can lead to action.
• Note the shop name, date and a witness. Photographs of the bill help.

We have not found a Rajasthan government notice about tagging that names a helpline or penalty, so we do not list one. Ask your district agriculture office for the current complaint number.

What is the difference between DAP and nano DAP?

DAP is a granular fertiliser with 18 percent nitrogen and 46 percent phosphate that goes into the soil at sowing. Nano DAP is a liquid with a small amount of nitrogen and phosphorus, used as a seed treatment or foliar spray. It can only partly replace DAP, and the PIB release says 50 percent substitution worked in "certain cases" such as potato.

Because phosphorus must be near the roots at sowing, spraying later cannot fix a missed basal dose. If DAP is hard to find, compare SSP and NPK options first in our DAP alternatives post.

Is nano urea banned or being replaced in India?

We found no ban in the sources we read. The PIB release of 20 March 2026 says nano fertilisers are included in the Department of Fertilizers' monthly supply plan and that sales have reached 1,219.27 lakh bottles of nano urea and 374.10 lakh bottles of nano DAP since launch. At the same time the government is funding long-term studies and has asked states to stop forced sale.

In short, nano fertilisers are still officially promoted, and the debate is about how much of the conventional dose they can replace. The Namo Drone Didi scheme, with an outlay of Rs 1,261 crore for 2023-24 to 2025-26, is also pushed to make foliar spraying easier. That is why Rajasthan is now backing supervised demonstrations instead of leaving farmers to decide on their own.

Mistakes that can cost you the subsidy or the crop

• Spraying before your name is in a cluster. The field check may not count it.
• Not keeping the bottle bill or a spray photograph.
• Using an inactive bank account or an account not linked for DBT.
• Spraying on wet leaves or before rain, which wastes the bottle.
• Reducing the basal dose too much because the scheme is about nano products.
• Reading old news. Earlier reports about Rajasthan and nano fertilisers mixed kharif and rabi rates. Check the date on any rate you rely on.
• Skipping a local check. Keep an unsprayed strip and compare at harvest, so you know whether the spray paid in your field.

What to do next as a Rajasthan farmer

Go to your village agriculture supervisor this week and ask three things: is a nano cluster planned in my village, how much of the district target is left, and which crop and product will be sprayed. Ask for the department order in writing or on paper. Meanwhile finish your basal dose on time, since sowing windows do not wait for subsidy approval.

Conclusion

Rajasthan is reportedly paying Rs 1,000 per hectare for a nano urea spray and Rs 1,450 per hectare for nano DAP this rabi, only through village clusters and after a field check, so ask your agriculture supervisor now. Treat nano as a supplement to a full basal dose and keep an unsprayed strip, because the research results are mixed.
