This study investigates the impact of different packaging materials and storage conditions on the shelf life of bottle gourd (Lagenaria siceraria L.), a commonly cultivated vegetable prone to rapid post-harvest deterioration. Four packaging materials—low-density polyethylene (LDPE), high-density polyethylene (HDPE), brown paper bags, and cotton bags—were evaluated under two storage conditions: room temperature and refrigeration. The physical and visual quality of the bottle gourds was assessed over five days based on changes in length, weight, diameter, and color (L*, a*, b* values). Results indicated that LDPE and HDPE were the most effective at preserving the freshness of bottle gourds, particularly when combined with refrigeration. Refrigeration significantly reduced reductions in length, weight, and diameter across all packaging types and maintained color stability, slowing shifts in lightness and hue. In contrast, brown paper and cotton bags, while eco-friendly, showed higher rates of moisture and color loss, especially at room temperature. Overall, LDPE and HDPE in refrigerated storage provided the optimal conditions for extending the shelf life of bottle gourds, suggesting that these materials are better suited for maintaining quality and reducing post-harvest losses. This study offers practical insights into packaging choices for farmers, distributors, and retailers, contributing to enhanced produce quality and reduced food waste in the fresh produce supply chain.
