The current experiment was conducted at the Biotechnology Advanced Research Centre Farm, Garki-Abuja during 2018 and 2019 to study the nutritional quality and nutrient uptake of ten accessions of winged bean. The experiment was laid out using Randomized Complete Block Design (RCBD) and replicated three times. Data collected on nutritional quality were protein, magnesium, carotene, iron, phosphorus, calcium and vitamin C and nutrient uptake elements were: nitrogen, phosphorus, calcium, potassium and magnesium respectively. The mineral contents were subjected to analysis of variance (ANOVA) and significant means compared using the Duncan Multiple Range Test (DMRT). Results revealed that among the nutritional quality of mineral content evaluated, phosphorus recorded the highest content obtained from TPT 9 (236.28 mg/100 g). Moreso, the highest nutrient uptake was obtained from calcium in accession TPT 6 (354.33 mg/kg). Overall, both nutritional qualities and nutrient uptake were significance (p≤0.05) from the study. Based on the results from this study, it could be concluded that for better nutritional quality and nutrient uptake, the accessions TPT 9 and TPT 6 could be particularly grown by farmers in this ecological area.
