Before
Onion farmers in Bangladesh experience substantial post-harvest losses due to traditional storage methods. The adoption of model household level storage (MHLS) technology and the User training program offers an adaptive and practical solution to reduce losses, maintain quality, and stabilize income. Hence, understanding the impact of such technology and knowledge on improving farmer welfare is essential. This study evaluates the effectiveness of Model Household Level Storage (MHLS) technology and user-focused training programs in reducing storage-related losses and improving market outcomes for onion producers in Bangladesh. To rigorously assess the intervention’s impact, we conduct a Cluster Randomized Controlled Trial (CRCT) across selected onion-producing areas. Clusters are randomly assigned into three groups: Treatment (T1): Farmers receiving MHLS Technology; T(2): Farmers receiving structured training on proper MHLS use, sorting, drying, and basic storage practices, Treatment (T3): Farmers receiving both the T2 intervention and additional labor support for onion drying, grading, and temperature monitoring, Control group (1): Farmers without MHLS Technology; Control Group (2): Farmers with access to standard practices, receiving no new intervention. The study's primary outcomes include Storage Pathological loss (%), Physiological Weight Loss (%), Storage Duration (days), Net Income from Stored Onion (BDT), Sales Frequency (times), and Average Market Price (BDT/kg).This study aligns with national policy goals (NAP 3.3.15.1-2018, NAMP 4.5.1-2023) and SDG targets (SDG 2.3, 12.3). Findings will inform government strategies on post-harvest loss reduction, and market access improvement. The evidence will support effective design and scaling of farmer-centered adaptive storage innovations across Bangladesh

Onion farmers in Bangladesh experience substantial post-harvest losses due to traditional storage methods. The adoption of model household level storage (MHLS) technology and the User training program offers an adaptive and practical solution to reduce losses, maintain quality, and stabilize income. Hence, understanding the impact of such technology and knowledge on improving farmer welfare is essential. This study evaluates user-focused pre-and post-harvest training programs in reducing storage-related losses and improving market outcomes for onion producers in Bangladesh. To rigorously assess the intervention’s impact, we conduct a Cluster Randomized Controlled Trial (CRCT) across selected onion-producing and storage technology used areas. Clusters are randomly assigned into two groups: Treatment : Farmers receiving Pre-and post-harvest training proram + A short user vedio; Control Group (2): Farmers with storage technology user but receiving no new intervention. The study's primary outcomes include Storage Pathological loss (%), Physiological Weight Loss (%), Storage Duration (days), Net Income from Stored Onion (BDT), Sales Frequency (times), and Average Market Price (BDT/kg).This study aligns with national policy goals (NAP 3.3.15.1-2018, NAMP 4.5.1-2023) and SDG targets (SDG 2.3, 12.3). Findings will inform government strategies on post-harvest loss reduction, and market access improvement.
