Women often involved in the processing and marketing of maize products. Yet, they are usually marginalized and lack access to resources that can help them improve their livelihoods. Therefore, we, assessed value addition in maize and empowerment of rural women in Osun state, Nigeria. Specifically, we identified the quantity produced of maize value-added products and various maize value activities, examined the empowerment status of women and assessed the effect of value addition on empowerment. A purposive sampling method was employed, selecting 5 Local Government Areas with maize farming households. Data were collected from 120 respondents through structured questionnaires and oral interviews, and analysis involved descriptive analysis, empowerment index and Tobit regression. The results indicated that the average monthly income was ₦67,740, and while value-added product revenue was profitable, most didn't exceed ₦100,000. Various maize products were produced, with different production levels and market values. Packaging, roasting, and steaming were the most common value-addition activities. Empowerment analysis revealed that the majority of rural women were not empowered, with limited education and income influencing their status. Tobit regression showed age, total revenue, and years of schooling as significant predictors of empowerment. In conclusion, rural women in Osun State engaged in maize value addition predominantly experience low empowerment levels due to various socio-economic factors. Recommendations include government support for financial, educational, and skill development initiatives and credit facilities. These measures aim to empower rural women and enhance their participation in value addition activities, thereby promoting gender equality and improving their livelihoods.
