Variety, planting distance and time of harvest affect the carotenoids in Sweet Potatoes (OFSP)

What is it about?

Two varieties of Orange-fleshed sweet potatoes were planted at three spacing distances (20,30 and 40cm). They were harvested after 12 weeks and after 16 weeks. the samples were analyzed for their carotenoid profiles, flavonoids, phenols, nutrient composition and other parameters. Planting at the 30cm distance led to an increased yield of carotenoid in both varieties.harvesting after 12 weeks favoured the carotenoid content and profile.

Why is it important?

The research indicates the proper time of harvest and the ideal planting distance for maximizing the pro-vitamin potentials of orange-fleshed sweet potatoes
