Abstract:
One third of citrus fruits produced in Nigeria is wasted due to post-harvest losses with an attendant increased de mand-supply gap of citrus. A reduction in post-harvest loss of orange will not only affect the income of both farm ers and marketers but also reduce the income inequality in its supply chain. This study investigated the post harvest loss effects on income inequality along the orange supply chain. Specifically, a multistage sampling tech nique was used to select sixty orange farmers, from Oyo and Ogbomoso Agricultural Development zones and 40
wholesalers and 80 retailers from four major fruit markets. Data were analysed using descriptive statistics, gross
margin analysis, Gini coefficient and Lorenz curve. Retailers had the lowest revenue $15.47/month) from orange,
while producers had the highest revenue ($318.44/month). Specifically, income inequality was higher among
wholesalers (0.82) than among producers (0.05) and retailers (0.56). Inequality was highest among wholesalers
with 6-10 percent post-harvest losses (0.8180) but lowest among farmers with post-harvest losses of ≤5 percent.
