Agronomic performance

The agronomic performance of To'o has been evaluated over three cropping cycles in 2 sites in Burundi and 3 sites each in the South and North Kivu provinces of the Democratic Republic of Congo. The values are averages of 8-10 plants evaluated over 3 cropping cycles at each of the 8 sites.

Nutritional value

The mean content in pro-vitamin A carotenoids of 3 ripe samples from North Kivu was 7,765 µg/100 g (fresh weight)[2]. Based on this value, the consumption of 100 g of ripe fresh pulp (approximately one finger) would contain 544 µg Retinol Activity Equivalent, or more than the daily recommended intake of Vitamin A for children under 5 years (400 RAE µg/day) and 75% of the daily recommended intake of Vitamin A for adult women (700 RAE µg/day).
