A 20-gunta polyhouse costs ₹4–7 lakhs to build. A complete drip irrigation system for one acre costs ₹55,000–80,000. These numbers stop many small farmers from investing in productivity-enhancing infrastructure — even when the return on investment is clearly positive. What most farmers do not know is that the government pays 55–75% of these costs upfront, not as a loan but as a non-repayable grant, through schemes that have been operating for years but are poorly publicised at the village level.
This guide explains the two main schemes — PM Krishi Sinchai Yojana for drip irrigation and the National Horticulture Mission for polyhouses — exactly what they cover, how to apply, and the single most important rule that prevents most farmers from claiming what they are entitled to.
The Most Important Rule — Apply Before You Purchase
This is where the majority of subsidy claims fail. Government subsidy for drip irrigation and polyhouse construction requires pre-approval — you must submit your application and receive a sanction letter before you purchase or install anything. If you install first and apply later, you will not receive the subsidy regardless of how eligible you are.
The government's reasoning is verification — they need to inspect the site before installation to confirm land eligibility, after installation to confirm what was actually installed, and cross-check purchase invoices against approved vendors.
Apply first. Install after sanction. This is non-negotiable.
Scheme 1 — PM Krishi Sinchai Yojana: Per Drop More Crop (Drip Irrigation)
What it covers: Drip irrigation systems including the main unit, sub-main pipes, lateral pipes, emitters, filters, and fertiliser injection equipment. Does not typically cover borewell drilling or pump installation — those are separate schemes.
Subsidy percentage:
- Small and marginal farmers (less than 2 hectares): 55% of unit cost
- Other farmers: 45% of unit cost
- SC/ST farmers: additional 10% top-up in most states
- Certain states (UP, Bihar, Odisha) offer additional state subsidy bringing total to 70–80%
Unit cost benchmark: The government sets a per-hectare benchmark cost for drip systems by crop type. Actual subsidy is calculated as a percentage of this benchmark, not your actual purchase price — so cost-effective procurement matters.
How to apply:
- Visit your district Agriculture Department office or Horticulture Department office
- Fill out the PMKSY application form (available online at pmksy.gov.in or at district office)
- Submit with: Aadhaar card, land ownership documents (7/12 or RTC), bank passbook, passport photo, Soil Health Card (if available), quotation from PMKSY-empanelled vendor
- Receive site inspection from Agriculture Officer
- Receive sanction letter with approved amount
- Purchase from approved vendor only — retain all invoices
- Post-installation inspection
- Subsidy credited directly to bank account (DBT) within 30–90 days
Empanelled vendor requirement: You must purchase from a vendor empanelled (approved) by the Agriculture Department. A list of approved vendors is available at your district office. Jain Irrigation, Netafim, Rivulis, and several regional manufacturers are typically empanelled. Buying from a non-empanelled vendor disqualifies the claim.
Scheme 2 — National Horticulture Mission (Polyhouse/Greenhouse)
What it covers: Construction of polyhouse (tubular structure with polyethylene film), shade net houses, and naturally ventilated polyhouses. The scheme is administered by the National Horticulture Board and state Horticulture Missions.
Subsidy percentage: 50% of the project cost for polyhouse construction, capped at government benchmark rates. For small and marginal farmers, some states offer 65–75%.
Benchmark cost (2024–25 unit costs):
- Naturally ventilated polyhouse (standard): ₹935–1,060 per sq metre (varies by state)
- Fan-and-pad cooled polyhouse: ₹1,290–1,465 per sq metre
- Shade net house (50%): ₹355–710 per sq metre
For a 500 sq metre (20 gunta) naturally ventilated polyhouse, the government benchmark cost is approximately ₹5 lakhs. At 50% subsidy for general category farmers, the grant is ₹2.5 lakhs.
How to apply:
- Apply at district Horticulture Office or through your state's horticulture portal
- Documents needed: same as PMKSY plus a project report specifying the structure size, crop to be grown, and quotation from approved contractor
- Land should be in applicant's name and free from legal disputes
- Minimum area: typically 500 sq metres (20 guntas) for individual farmer applications
- FPOs can apply for larger collective polyhouse projects under the scheme
Combining Both Schemes
There is no restriction on applying for both polyhouse subsidy and drip irrigation subsidy simultaneously — in fact, they are designed to be combined. A standard polyhouse application includes the drip irrigation system inside it, and both can be submitted together in a single project report.
Combined subsidy on a ₹7 lakh polyhouse with integrated drip:
- Polyhouse construction ₹5.5 lakhs: 50% subsidy = ₹2.75 lakhs
- Drip irrigation inside polyhouse ₹1.5 lakhs: 55% = ₹82,500
- Total government contribution: ₹3.57 lakhs on a ₹7 lakh investment
Your actual out-of-pocket cost: ₹3.43 lakhs for infrastructure that generates ₹6–10 lakhs per year from Year 2.
Processing Time and What to Watch For
Plan for 3–6 months from application to subsidy receipt. Common delays: incomplete documentation at submission (check every document against the checklist), site inspection scheduling (follow up weekly with the Agriculture Officer), and DBT bank account issues (ensure your bank account is Aadhaar-linked and active).
Keep copies of every document you submit and every communication with the department. If there is no response within 30 days of a complete application, file a written follow-up and note the date.
