Improving NSPRI Technologies through Targeted Stakeholders' Feedback: A Case Study of Bauchi and Nasarawa States, Nigeria. Nigerian Journal of Post-Harvest Research, 3(3), 1-7.

Agriculture is still the backbone of Nigeria's economy, providing jobs for over 70% of the population and significantly contributing to the nation's Gross Domestic Product (GDP). This study investigates the adoption and impact of two postharvest technologies; Hermetic Steel Drums (HSD) and Parabolic-Shaped Solar Dryers (PSSD) among smallholder farmers in Bauchi and Nassarawa States, Nigeria. The research focuses on farmers' socioeconomic characteristics, adoption patterns, income effects, stakeholder perceptions, technology improvements, and willingness to pay. The objectives were to evaluate the effects of using NSPRI technologies on income before and after adoption, and to assess stakeholder feedback on the technology enhancement. A multi-stage sampling technique was employed to select 121 participants for the study. Findings revealed a high willingness to pay for both technologies, with 98.6% for HSD and 98.1% for PSSD. However, there is a notable difference in user engagement: while 50.7% of HSD users reported sharing feedback, only 21.2% of PSSD users did so. Agricultural Development Programs (ADPs) were the primary feedback channels (44.9% for HSD and 11.5% for PSSD). Users identified areas requiring improvement, including the drum's capacity (HSD), tray size, air vent, and aspirator design (PSSD). The study highlights the critical role of stakeholder engagement in enhancing postharvest technologies. It emphasises the need to address systemic constraints and minimal credit access to promote sustainable adoption and scalability.
