Postharvest Weight Loss Assessment of Leeks from Farmgate to The Retailer Market in Sri Lanka: A Case Study in Nuwara Eliya District

Abstract

eeks is a significant vegetable crop in Sri Lanka, primarily cultivated in the upcountry region. After harvest, these perishable vegetables are transported to various parts of the country and even to foreign markets. During their journey along the market chain in the wet zone, yield losses can occur from the farmer's field to the retailer's market. This study was conducted to measure the yield loss of leeks along this market chain and to identify specific factors contributing to this reduction. Random samples of harvested leeks (Mesh bags) were collected from the field, wholesale markets in Nuwara Eliya and Meegoda, and retail markets in Colombo to analyze the market chain. Weights were measured at each location, and postharvest practices like handling, packing, and transporting were observed and discussed with stakeholders. The study revealed that the total yield loss along the market chain was 40.09% by weight. A substantial portion of this loss, 78.98%, occurred during transportation to the retailer market and afterward, during the sorting and cleaning processes. Given the high level of yield loss, it is crucial to implement strategies to minimize these losses at each stage of the market chain to reduce economic losses for individuals and the nation.
