1. Regional Context & Agricultural Challenge

Bogura is Bangladesh’s premier vegetable hub, but growing sweet pepper (Capsicum) in open soil often resulted in viral leaf curl from whiteflies, sunscald, and small, deformed fruits.

2. Technical Implementation & BARI Protocol Applied

Progressive growers in Shahjahanpur built 200-micron UV polyhouses fitted with 60-mesh insect nets and BARI circulating trays. Plants are pruned to 2–3 main stems, supported with twine at 30 days after transplanting, and fed a calcium-rich EC 2.3 dS/m solution.

3. Harvest Results, Economic Impact & Grower Outcome

Protected from thrips and mites by insect netting, growers harvest thick-walled, 180–220g bell peppers from October through April without toxic chemical sprays.
