Storage mechanisms and post harvest losses in mangoes: a case of three major markets in Kampala city.

Abstract

This study examines the effect of storage mechanisms on post-harvest losses of mangoes in three major food markets in Kampala City, addressing significant economic losses and food insecurity caused by high post-harvest losses in the mango value chain. The research employs a cross- sectional study approach, incorporating both quantitative and qualitative data to comprehensively analyze the issue. The specific objectives are to characterize mango traders using different storage technologies, determine the factors influencing the quantity of mangoes lost, and investigate the challenges faced by traders during post-harvest management. Data analysis techniques include univariate analysis using frequency tables, Analysis of Variance, and multivariate analysis with multiple linear regression. The study finds that baskets, plastic crates, wooden crates, basins and boxes are the major storage methods used by mango traders. Physical injuries and deformation from compression are the most prevalent storage issues, leading to substantial economic losses, as traders often sell spoilt mangoes at a low price or discard them. Financial constraints, limited capital, and lack of knowledge on post-harvest practices are identified as the major constraints to post-harvest loss management. Significant factors affecting mango spoilage include working experience, mode of transport, training, and the type of storage method used. The use of wooden and plastic crates is associated with reduced spoilage, while basins and boxes increase spoilage. The findings underscore the need for improved storage solutions and better training for traders. Recommendations include increasing access to affordable and effective storage technologies, enhancing trader training programs on post-harvest management and the effectiveness of training programs. This study aims to inform policymakers and stakeholders in the agricultural sector to implement strategies that minimize post-harvest losses, thus improving food security and economic outcomes for mango traders
