Mothers’ vitamin A (VA) status during pregnancy and lactation determine infants’ VA levels. We estimated VA status during pregnancy and assessed its determinants using data on 505 pregnant women attending first antenatal care visit in Western Kenya. VA and iron status were assessed using plasma r...

Different drying treatments, cross flow, greenhouse solar, and open-air sun, were applied to an American orange-fleshed sweetpotato variety. Trans-?-carotene losses in flour made from dried chips varied between 16 and 34% in all treatments. Hot air cross flow drying retained significantly more pr...

Long-term storage of sweetpotato roots is a great challenge for smallholder farmers in Mozambique. Piecemeal harvesting allows several months supply of roots for household consumption provided weevil infestation is avoided. The objectives of the present studies were to determine yield and changes...

In sub-Saharan Africa, more than 40% of children under five years of age suffer from vitamin A deficiency. Among several interventions in place to address vitamin A deficiency is biofortification, breeding vitamin A into key staple crops. Staple crops biofortified with beta-carotene, the precurso...

The study was carried out to establish the proportions of cassava and sweetpotato flours that would produce good quality pasta, in composite with wheat flour. Up to 50% sweetpotato and cassava flour substitutions were made. Two varieties each of cassava (Abasafitaa and Afisiafi) and sweetpotato (...

We examined the effect of multidimensional farmers’ beliefs on the likelihood of cultivating planting materials of biofortified orange-fleshed sweetpotato (OFSP) varieties. Using a panel dataset and combining difference-in-differences regression with propensity score matching, results showed posi...

Whiteflies of the Bemisia tabaci species complex are economically important pests of cassava. In Africa, they cause greatest damage through vectoring viruses responsible for cassava mosaic disease and cassava brown streak disease. Several cryptic species from the B. tabaci complex colonize cassav...
