NHB Polyhouse Subsidy Guide — Revised July 2026

The National Horticulture Board (NHB), an autonomous body under the Ministry of Agriculture & Farmers Welfare, Government of India, provides a 50% credit-linked back-ended subsidy for high-tech commercial polyhouses and protected cultivation projects across India. The scheme operates under the Mission for Integrated Development of Horticulture (MIDH) umbrella, with revised operational guidelines and cost norms effective from January 2025 (and further modified via notification dated 12 August 2025).

As of July 2026, the NHB has fully discontinued the earlier two-stage In-Principle Approval (IPA) system. Applicants now apply directly for a Grant of Clearance (GoC) through the NHB online portal after securing a bank term loan sanction. The entire GoC processing is fully digital, with built-in timeline monitoring, automated alerts, and Aadhaar OTP verification.

Protected cultivation in an NHB-approved polyhouse yields 5× to 10× higher production per acre compared to open-field farming, with 50% to 70% savings in water usage through drip irrigation and fertigation systems. Agri Twist Private Limited manufactures and installs NHB-compliant GI structures, UV-stabilized poly films, and climate control equipment, while providing 100% end-to-end DPR preparation, bank loan facilitation, and GoC filing assistance.

NHB calculates the credit-linked back-ended subsidy based on standard government cost norms per square meter prescribed under the MIDH Operational Guidelines. Below are the official unit cost norms and subsidy rates applicable:

1. Naturally Ventilated Polyhouse (NVPH — Tubular Structure): Unit Cost Norm: ₹1,090 per sqm. Subsidy: ₹500 per sqm. Minimum eligible area: 4,000 sqm (General Regions). Ideal for commercial vegetable and flower cultivation under natural airflow.

2. Fan & Pad Climate Controlled Greenhouse: Unit Cost Norm: ₹1,700 per sqm. Subsidy: ₹700 per sqm. Engineered for extreme summer heat with automated evaporative cooling pads and exhaust fan systems for year-round precision farming.

3. Shade Net House (Tubular Structure): Unit Cost Norm: ₹720 per sqm. Subsidy: ₹360 per sqm. Durable anti-insect mesh for high-value vegetable cultivation and nursery operations.

Note: Cost norms are 15% higher for North-East, Himalayan states, Scheduled Areas, Vibrant Villages, and island territories (Andaman & Nicobar, Lakshadweep). Maximum subsidy ceiling is up to ₹1 Crore per beneficiary project. The subsidy is released directly to your bank term loan account upon physical joint inspection after structural installation is completed.
