Introduction

Polyhouse and greenhouse farming lets growers control temperature, humidity, and pests, often multiplying yields for high-value crops like capsicum, tomato, and cut flowers. Setting one up is capital-intensive, though, which is why the Government of India offers a back-ended capital subsidy of up to 50% of project cost. It's worth being precise about who does what here: the subsidy itself comes from the National Horticulture Board (NHB) for larger commercial projects and the National Horticulture Mission (NHM) under MIDH for smaller farmer-scale units, routed through state Horticulture Departments. NABARD's role is on the credit side — it refinances the banks that fund the loan portion of these credit-linked projects, and separately supports Farmer Producer Organisations (FPOs) taking up protected cultivation. Understanding this split matters because farmers apply to NHB/NHM for the subsidy and to a bank (often NABARD-refinanced) for the loan — not to NABARD directly for the subsidy.

Polyhouse Subsidy Scheme Overview

• Subsidy-Granting Bodies — National Horticulture Board (NHB) for commercial-scale projects; National Horticulture Mission (NHM) under MIDH for small/medium farmers, via state Horticulture Departments
• NABARD's Role — Refinances participating banks on the credit-linked loan portion; does not disburse the polyhouse subsidy itself
• Subsidy Rate — Base 50% of admissible project cost (credit-linked, back-ended); several states add a top-up, taking total support to 65–95% for eligible categories
• Maximum Subsidy — Up to ₹56 lakh–₹1 crore per project under NHB, depending on structure type and location
• Type of Scheme — Central Government (NHB/MIDH), implemented via state Horticulture Departments and empanelled banks
• States Covered — All India, with several states offering additional top-up subsidy

Objectives of the Scheme

• Encourage protected cultivation to boost yield, quality, and off-season availability of high-value horticultural crops.
• Reduce dependence on open-field farming that is vulnerable to weather, pests, and water stress.
• Make capital-intensive polyhouse structures financially accessible to small and marginal farmers.
• Promote export-quality produce and better price realisation through controlled-environment farming.
• Support FPOs and agri-entrepreneurs entering high-value protected cultivation.

Key Features of the Polyhouse Subsidy

• Subsidy is credit-linked and back-ended: the farmer first takes a bank loan and builds the polyhouse, and the subsidy is credited to the loan account only after a government inspection confirms the structure.
• Under NHB, commercial projects generally require a minimum area of 4,000 sq m (1,000 sq m for North East and hilly regions), with a subsidy cap of roughly ₹56 lakh, extendable to ₹1 crore for certain structures.
• Under NHM/MIDH, smaller units from about 500 sq m to 4,000 sq m are supported, aimed at small and medium farmers, and applications are managed at the district level.
• Cost norms are fixed by structure type — for example, roughly ₹1,000/sq m for a naturally ventilated polyhouse and ₹1,600/sq m for a fan-and-pad greenhouse — and the 50% subsidy is calculated on this norm, not necessarily the actual bill.
• NABARD-refinanced bank loans cover the balance project cost after subsidy, and NABARD separately supports FPO-led protected cultivation projects.

Polyhouse Subsidy Benefits to Farmers

• Up to 50% (and in some states, considerably more) of project cost covered as capital subsidy, sharply reducing the farmer's net investment.
• Access to institutional bank credit for the balance cost, rather than relying on informal high-interest borrowing.
• Support for both large commercial units (via NHB) and smaller individual farmer projects (via NHM), covering a wide range of farm sizes.
• Higher subsidy slabs in several states for SC/ST, women, and small/marginal farmers.
• Higher yields, better crop quality, and extended growing seasons that can significantly raise farm income.

Limitations of the Scheme

• The subsidy is credit-linked — farmers without an approved bank loan cannot claim it, and self-financed projects are not eligible.
• Subsidy is calculated on fixed government cost norms, which often run 15–20% below actual market construction costs, so the effective subsidy on the real project cost can work out lower than the headline 50%.
• Only GI-grade pipes and specified materials generally qualify; using non-compliant materials (such as MS pipes) can disqualify the project.
• The approval process — including in-principle approval, construction, joint inspection, and fund release — commonly takes 6 to 12 months, so working capital must be arranged to cover this waiting period.
• A farmer or entity can generally avail one primary subsidy route (NHB or NHM) per project, not both simultaneously.

Documents Required

• Aadhaar Card and other valid photo ID proof
• Land ownership document or a registered lease deed (typically 10–15 years minimum for leased land)
• Detailed Project Report (DPR) with cost breakdown by structure type
• Bank loan sanction letter or in-principle approval
• Caste/category certificate, where applicable, for enhanced state subsidy slabs
• Site photographs and, after construction, dated invoices and material delivery receipts for inspection

How to Apply for Polyhouse Subsidy

• Prepare a Detailed Project Report specifying structure type, area, crop plan, and total cost.
• Approach a bank for loan sanction; NABARD refinance support strengthens the bank's ability to offer this credit.
• For commercial-scale projects, apply online through the NHB portal (nhb.gov.in) for in-principle approval before starting construction.
• For smaller farmer-scale projects, apply through the District Horticulture Officer or the relevant state portal (such as HORTNET, iKhedut, or MAHA-DBT) under NHM/MIDH.
• Construct the polyhouse as per approved specifications; after a Joint Inspection Team verifies the project, the subsidy is credited to the bank loan account.

Conclusion

Polyhouse farming can transform returns for growers of high-value crops, but the up-front cost is a real barrier — which is exactly what the NHB and NHM/MIDH subsidy routes are designed to ease. NABARD's part in this ecosystem is the credit backbone: refinancing the banks that fund the loan portion of these credit-linked projects. Farmers planning a polyhouse should start with a realistic project report, decide between the NHB and NHM route based on project size, and line up bank financing early, since the subsidy is released only after construction and inspection.

Disclaimer: Subsidy rates, cost norms, area limits, and state top-ups are subject to periodic revision and vary by state and structure type. NABARD refinances the credit-linked loan component of these projects and is not the body that grants the polyhouse subsidy itself. Readers are advised to verify the latest details on the official NHB website (nhb.gov.in), the MIDH/NHM guidelines, their state Horticulture Department portal, or with their nearest bank branch before applying or making any financial decision.
