Sherpur (Bogura) & Natore: Commercial Sponge-Block Hydroponic Seedling Nurseries Supply Disease-Free Plugs to Growers
📊 Case Study Technical & Economic Profile
1. Regional Context & Agricultural Challenge
New hydroponic growers often failed in their first month because they washed soil-grown nursery seedlings and transferred Pythium/Fusarium root pathogens directly into their clean water tanks.
2. Technical Implementation & BARI Protocol Applied
Specialized nursery entrepreneurs in Bogura and Natore adopted BARI Chapter 2 Sponge-Block propagation: scoring sponge sheets into 2.5 × 2.5 cm cubes, cutting a 1 cm slit in each cube to insert 1–2 seeds, soaking the tray in water for 5–6 days until emergence, and feeding half-strength (5 mL/L) BARI Stock A & B for 14 days.
3. Harvest Results, Economic Impact & Grower Outcome
Growers across North Bengal can now buy ready-to-transplant, 100% soil-free sponge-block seedlings with snow-white roots and zero transplant shock.
This verified case study from Sherpur (Bogura) & Natore Sadar, Bogura & Natore demonstrates how adapting BARI Stock Solution A & B and localized soilless structures solves real regional climate and soil constraints while delivering strong commercial returns in Bangladesh.
