1. Regional Context & Agricultural Challenge

Rural growers in Narsingdi faced two simultaneous hurdles: heavy bacterial wilt in intensive vegetable soils and rural load-shedding that interrupted electric water pumps.

2. Technical Implementation & BARI Protocol Applied

Farmers adopted BARI’s Chapter 4 Non-Circulating Tray design: wood-and-polythene or galvanized trays where nutrient solution is filled manually, leaving a 5–8 cm air gap beneath the cocksheet so upper feeder roots breathe oxygen directly from the air without any electric pump.

3. Harvest Results, Economic Impact & Grower Outcome

Growers achieved 100% plant survival with zero electricity bills and zero wilt disease, proving that commercial hydroponics works even in off-grid rural villages.
