What is it about?

This study contributes to the existing literature of the effect of farming practice: planting distance and harvesting time on the nutrient composition of OFSP cultivars (Umuspo 3 and Ex-Igbariam) grown in Nigeria. Results showed that Ex-Igbariam was the best OFSP cultivar with dense nutrient content. This research finding can be used to advocate for increased OFSP utilization in Nigeria.

Why is it important?

Orange-fleshed sweet potatoes are usually rich in pro-vitamin a carotenoids. Ash, carbohydrates, fibre contents were found to be higher in samples harvested after 16 weeks while moisture and proteins were higher in samples harvested after 12 weeks for the two varieties (Ex-Igbariam and Umuspo 1)
