1. Regional Context & Agricultural Challenge

Bottle gourd (Lau) is a staple vegetable across Bangladesh, but traditional pit cultivation requires large mounds of fertile soil and heavy manure that urban rooftops and flood-prone homesteads lack.

2. Technical Implementation & BARI Protocol Applied

Following BARI Chapter 5 Bottle Gourd protocols, women growers germinate BARI Lau-4 seeds in sponge blocks and transplant them into 10-liter plastic buckets, replenishing Stock A & B solution weekly and doing complete solution changes at 30 days.

3. Harvest Results, Economic Impact & Grower Outcome

Harvesting starts just 60–70 days after planting, yielding 8 to 12 tender 1.5–2.0 kg bottle gourds per bucket.
