Abstract

Onion bulbs (Allium cepa L.), a staple in global cuisine, are valued for their distinctive flavor, texture, and nutritional benefits. However, maintaining their quality during storage presents challenges, particularly under conventional methods used in regions like northern Nigeria. This study compares the effects of two storage techniques wooden platforms and cemented floors on key quality parameters of onion bulbs, including storage loss, dry matter (DM) content, total soluble solids (TSS), firmness, pungency, and yield. A systematic evaluation was conducted, measuring parameters such as DM content, TSS (via hand refract meter), firmness (subjective scale), pungency (sensory evaluation), and storage loss over six months. Statistical analyses determined significant variations between storage methods. Wooden platforms demonstrated superior quality preservation, with lower storage loss (21.8%), higher firmness (8.00), greater DM content (17.7%), elevated TSS (17.3 °Brix), and enhanced pungency (3.00). Conversely, cemented floors yielded a higher bulb dry yield (2.27 t/ha), highlighting its productivity potential. These findings emphasize the critical role of storage techniques in preserving onion quality and ensuring market value. Wooden platforms are recommended for their ability to retain quality attributes crucial for consumer satisfaction and extended shelf life, while cemented floors are better suited for maximizing yield. This research provides practical insights for optimizing onion storage strategies to meet diverse agricultural and market demands.
