Everyone quotes “50% subsidy.” Almost nobody explains what that 50% is actually calculated on — and that gap is where most farmers get caught off guard.
Ask around about polyhouse subsidy in India and you’ll hear the same line everywhere: “MIDH gives 50%.” True, but incomplete. The 50% isn’t calculated on what you actually pay your vendor — it’s calculated on a fixed government cost norm that’s often lower than real market rates. That single detail is responsible for more disappointed farmers than any other part of the scheme. So let’s actually unpack MIDH properly, the way we explain it to clients before they apply.
What MIDH Actually Is
MIDH stands for Mission for Integrated Development of Horticulture — it’s the central government’s umbrella scheme run by the Ministry of Agriculture and Farmers Welfare. It doesn’t work alone; it brings together older schemes like the National Horticulture Mission (NHM) and routes funding through the National Horticulture Board (NHB) for larger projects. In practice, as a polyhouse farmer, you’ll deal with one of two routes under this umbrella, and picking the right one matters.
Covers structures from 500 sqm up to 4,000 sqm (roughly 1 acre)
Base subsidy: 50% of the government’s fixed cost norm
Applied through your District Horticulture Officer (DHO), or your state’s DBT portal — in Gujarat, that’s the i-Khedut portal
NHB route (larger commercial projects):
Typically for bigger structures, above the NHM range
Subsidy: also 50% of admissible cost, but capped around ₹56 lakh per beneficiary
Applied directly through nhb.gov.in
For most first-time polyhouse farmers on 1–2 acres, NHM through the DHO is the more practical and faster route. NHB tends to suit larger commercial or repeat projects where the higher cap actually matters.
The Cost Norm Trap — Read This Before You Do Any Math
Here’s the part that trips up almost every farmer we talk to. The government fixes a “cost norm” per square meter for each structure type — currently around ₹1,000/sqm for a naturally ventilated polyhouse and roughly ₹710/sqm for a shade net house. Your 50% subsidy is calculated on this number, not on the actual invoice your vendor gives you.
The problem is that real construction costs — steel, UV film, labour, GST — usually run 15–20% above the government’s norm, especially in the last couple of years. So if your actual project costs ₹42 lakh but the cost-norm calculation caps the subsidy base lower, you don’t get 50% of ₹42 lakh. You get 50% of the government’s lower figure. That difference comes straight out of your pocket or gets added to your loan amount.
Two Rules That Are Non-Negotiable
1. The subsidy is credit-linked. You cannot self-finance the whole project and then ask for a refund. A term loan from a scheduled bank, cooperative bank, or NABARD-refinanced institution is mandatory for most MIDH-linked subsidies. The subsidy amount gets credited directly into your loan account after construction is inspected and approved — this is what “back-ended” means.
2. Never start construction before approval. This is the single most common reason applications get rejected outright. If you begin building before receiving the official Letter of Intent or administrative approval, you are permanently disqualified from that subsidy — no exceptions, no appeals. We’ve seen farmers lose out entirely simply because they were excited and got a head start.
What You’ll Need Before You Apply
| Requirement | Why it matters |
|---|---|
| Land ownership or registered lease (10–15 yrs) | An unregistered or short-term lease is usually rejected outright |
| Detailed Project Report (DPR) | Mandatory for every application — needs to hold up to both bank and government scrutiny |
| Vendor quotations with GST invoices | Handwritten or “kacha” bills from local fabricators are not accepted for subsidy claims |
| Bank loan sanction letter | Required before your subsidy file can move forward at all |
| Letter of Intent / administrative approval | Must be in hand before a single pole goes into the ground |
Don’t Forget the State Top-Up
The 50% figure is just the central government’s base contribution. Several states add their own top-up on top of it — Haryana and Rajasthan, for instance, push total assistance well past 50%, and some categories in other states go even higher. Gujarat runs its own scheme layered on top of the central MIDH support through the i-Khedut portal, so it’s worth checking current state-specific rates with your DHO before finalising your budget — these get revised annually.
A Realistic Timeline
From application to actual fund release, most farmers should plan for 6 to 12 months — covering approval, construction, joint inspection, and final disbursement. Apply early in the financial year, ideally April to June, when fresh budget allocations are typically available and processing tends to move faster. Also make sure you have enough working capital to manage loan EMIs during this waiting period, since the subsidy only lands after inspection, not before.
Frequently Asked Questions
Is MIDH the same as NHB subsidy?
Not exactly. NHB operates as one of the funding channels under the broader MIDH umbrella, generally used for larger commercial projects. NHM, also under MIDH, is the route most small and medium farmers use. Both share the same core 50% principle, but with different area limits and application processes.
Can I get the subsidy without taking a bank loan?
Generally no. Most MIDH-linked subsidies are credit-linked by design — a bank loan is a structural requirement, not just a suggestion. Self-financing the whole project and later claiming a refund isn’t how the scheme works.
What happens if my actual construction cost is higher than the government cost norm?
You still get 50% of the fixed cost norm, not 50% of your actual bill. The difference becomes part of your own contribution or gets added to your loan margin — this is the single most misunderstood part of the scheme.
Can I apply for MIDH subsidy on leased agricultural land?
Yes, as long as the lease is formally registered (not just notarized) for a minimum of 10 to 15 years, depending on the specific scheme guidelines in force that year.
Subsidy rates, cost norms, and eligibility criteria are revised periodically by the Ministry of Agriculture and Farmers Welfare and respective state horticulture departments. Figures in this article are indicative as of 2026 — please verify current rates with your District Horticulture Officer or at nhb.gov.in before applying.
