The Dynamics of Postharvest Loss Management among Cassava Farmers in the Iwo ADP Zone, Osun State in Nigeria

In Nigeria, poor management of postharvest losses (PHL) in perishable crops is driving food wastage and contributing to rising food insecurity. This study examines the dynamics of cassava PHL management in the Iwo ADP Zone, Osun State, Nigeria, focusing on the postharvest practices of cassava farmers and the factors influencing effective PHL management. A multi-stage random sampling technique was employed to select 120 cassava farmers, and data were collected through a structured questionnaire. Descriptive statistics, budgetary analysis, and multiple regression models were used to analyze the data. The findings revealed that cassava production is predominantly male-dominated, with 52.9% of farmers lacking PHL training. While cassava farming is profitable, with a net return of ₦0.73 for every naira invested, farmers experienced an average loss of 2,062 kg of tubers, resulting in an unrealized income of ₦25,506. Multiple regression analysis showed a significant negative correlation between farmers' age, farm size, distance to the nearest market, and postharvest management practices (P ≤ 0.05). On the other hand, factors such as farmers' education, access to improved storage facilities, and the use of modern harvesting techniques were positively associated with better postharvest outcomes (P ≤ 0.01). The study also identified key challenges to effective PHL management, including the high cost of processing equipment and the lack of proper storage facilities. The study recommends that development partners prioritize enhancing farmers' educational training, ensuring the effective dissemination of relevant technological information, and providing access to credit facilities to support postharvest management.
