Sitakunda & Halishahar, Chattogram: Port City Entrepreneurs Overcome Coastal Humidity with Circulating Hydroponic Tomatoes
📊 Case Study Technical & Economic Profile
1. Regional Context & Agricultural Challenge
Chattogram’s coastal groundwater salinity in Halishahar and flash runoff from hills in Sitakunda make year-round high-value tomato production difficult in open fields.
2. Technical Implementation & BARI Protocol Applied
Using harvested monsoon rainwater blended with low-EC municipal water, growers established elevated circulating trays equipped with Venturi injectors to maintain dissolved oxygen above 6.5 mg/L even during warm coastal summers.
3. Harvest Results, Economic Impact & Grower Outcome
The farm now holds steady supply contracts with international ship chandlers at Chattogram Port and superstores in Khulshi and Nasirabad.
This verified case study from Sitakunda & Halishahar, Chattogram 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.
