Abstract: This study investigated how physical and functional quality attributes influence ginger prices in Nigeria using a hedonic pricing model. A total of 960 ginger retailers were selected from 480 Enumeration Areas across 15 states and the Federal Capital Territory through a multistage sampling procedure. The research covered major ginger-producing and consuming regions to capture geographical differences in market characteristics and price formation. Descriptive statistics were used to profile retailers, while hedonic regression analysis assessed the effect of quality attributes on market prices. The results revealed notable socioeconomic differences between market categories. Female retailers dominated in producing states, whereas male retailers were more prevalent in consuming states. The average age of retailers was 42 years in producing states and 40 years in consuming states, indicating that participants were largely within economically active age groups. Although quality characteristics were generally similar across regions, average retail prices were higher in producing states (₦1,586 kg-1) than in consuming states (₦1,504 kg-1). The hedonic model for producing states demonstrated very high explanatory power, accounting for approximately 99% of price variation (R2 = 0.9903). Emulsion capacity and texture significantly increased ginger prices, while larger bulb size and higher oil-holding capacity reduced market value. In consuming states, the model explained 70.16% of price variation (R2 = 0.7016). Hygroscopicity positively influenced prices, whereas texture deterioration and larger bulb size significantly lowered them. Overall, both physical and functional quality attributes significantly affected ginger prices, though their influence differed across market groups. Promoting quality-based grading and marketing could enhance value capture, improve market efficiency, and strengthen competitiveness within Nigeria’s ginger value chain.
