1. Greenhouse / Polyhouse Establishment & Regional Agricultural Challenge

Vegetable and flower growers in Jashore and Savar lost 35–50% of their soil-bed seedlings every monsoon to damping-off (Pythium/Phytophthora) and early whitefly-transmitted leaf curl virus (TYLCV) before transplanting.

2. Drip Irrigation BD Ltd. (DIBL) High-Tech Engineering & Soilless Implementation

By establishing a double-door 50-mesh insect-proof polyhouse with a UV-200 micron roof and raised wire-mesh benches, the nursery eliminated soil contact completely. Drip Irrigation BD Ltd. (DIBL) installed automated 4-way anti-drip overhead micro-foggers and precision drip lines controlled by a second-interval digital timer to keep 104-cell cocopeat trays uniformly moist.

50-Mesh Double-Door Insect-Proof Polyhouse with Raised Galvanized Bench Tables — 🏡 **BARI / Bangladesh Polyhouse Interior Benchmark:** Protected cultivation crop canopy inside a UV-stabilized greenhouse in Bangladesh.

3. Agronomic Yield, Resource Savings & Commercial Return on Investment

Seedling mortality dropped below 2%, root balls develop dense white fibrous roots in 22 days, and the nursery now supplies over 250,000 virus-free seedlings per batch to commercial farms across southwestern and central Bangladesh.
