Determinants and Constraints to Consumption Pattern of Worowo (Solanecio biafrae), IGBAGBA (Solanum macrocarpon), ODU (Solanum nigrum) and Elegede (Cucurbita pepo) Vegetables in South West Nigeria

This study examines the determinants and constraints influencing the consumption patterns of underutilized indigenous vegetables—worowo (Solanecio biafrae), igbagba (Solanum macrocarpon), odu (Solanum nigrum), and elegede (Cucurbita pepo)—in Southwest Nigeria, a region grappling with micronutrient deficiencies and dietary monotony. A multistage sampling technique was employed across Oyo and Ogun States, selecting 123 respondents from agricultural zones, blocks, and cells. Data were analyzed using descriptive statistics and ordered logit regression to identify socioeconomic and market-related factors affecting consumption. Key findings reveal that worowo is the most consumed (56%), driven by availability (64%) and nutritional benefits (54%). Regression results highlight significant determinants: male respondents (p<0.01) and proximity to markets (p<0.01) positively influence consumption, while higher monthly income negatively impacts it (p<0.05), suggesting substitution with conventional alternatives as socioeconomic status rises. Constraints include limited access to credit (78% lacked access) and minimal nutritional guidance from extension agents (77% unreached). The study underscores the potential of indigenous vegetables to mitigate hidden hunger and diversify diets. Recommendations emphasize promoting cultivation and consumption through awareness campaigns, market accessibility improvements, and integration into agricultural policies to enhance food security and livelihoods. Addressing these factors could reposition underutilized vegetables as sustainable contributors to Nigeria’s nutritional and economic resilience.
