Lam] genotypes for combined beta carotene and dry matter content in southern guinea savanna, Nigeria.]Diallel analysis of sweetpotato [Ipomoea batatus (L.) Lam] genotypes for combined beta carotene and dry matter content in southern guinea savanna, Nigeria.

Abidin, P.E.Dery, E.Amagloh, F.K.Asare, K.Amoaful, E.F.Carey, E.E.[Training of trainers’ module for orange-fleshed sweetpotato (OFSP)]Training of trainers’ module for orange-fleshed sweetpotato (OFSP)

This study assessed the genetic diversity and differentiation in sweetpotato accessions in Ghana to guide selection for genetic improvement on beta-carotene, dry matter and sugar contents to promote increased utilization. One hundred and fifteen sweetpotato accessions from four different sources,...


Baafi, E.Gracen, V.E.Blay, E.T.Ofori, K.Manu-Aduening, J.A.Carey, E.E.[Evaluation of sweetpotato accessions for end-user preferred traits improvement]Evaluation of sweetpotato accessions for end-user preferred traits improvement

Sweetpotato is used in various food preparations in place of rice, cassava, yam and plantain in Ghana. In spite of this it does not have the same importance in Ghanaian diet as other root and tuber crops. Consumer taste, preference and acceptance are critical in determining the suitability of swe...

Sweetpotato (Ipomoea batatas L. (Lam)) is a nutritious food security crop for most tropical households, but its utilisation is very low in Ghana compared to the other root and tuber crops due to lack of end-user-preferred cultivars. Knowledge on the genetic control of important traits such as dry...


Baafi, E.Gracen, V.E.Manu-Aduening, J.A.Blay, E.T.Ofori, K.Carey, E.E.[Genetic control of dry matter, starch and sugar content in sweetpotato]Genetic control of dry matter, starch and sugar content in sweetpotato

Dark green leafy vegetables (DGLVs) are considered as important sources of iron and vitamin A. However, iron concentration may not indicate bioaccessibility. The objectives of this study were to compare the nutrient content and iron bioaccessibility of five sweet potato cultivars, including three...


Amagloh, F.K.Atuna, R.A.McBride, R.Carey, E.E.Christides, T.[Nutrient and total polyphenol contents of dark green leafy vegetables, and estimation of their iron bioaccessibility using the In Vitro digestion/Caco-2 cell model]Nutrient and total polyphenol contents of dark green leafy vegetables, and estimation of their iron bioaccessibility using the In Vitro digestion/Caco-2 cell model

Commonly used innovation adoption models indirectly assume homogenous information flow across farmers, which is often not the case. For new and or not well known technologies such as Orange-fleshed sweetpotato (OFSP) varieties, awareness exposure plays an important role in farmers’ decision to ad...


Adekambi, S.Abidin, P.E.Okello, J.J.Carey, E.E.[Awareness exposure and technology adoption: the case of orange-fleshed sweetpotato in West Africa.]Awareness exposure and technology adoption: the case of orange-fleshed sweetpotato in West Africa.

This study estimated the amount of loss in storage roots caused by various levels of damage caused by sweetpotato weevils (Cylas spp). Seven varieties of sweetpotato (Ipomoea batatas L. (Lam)) were evaluated in three production sites in northern Ghana for two years (2014 and 2015). Yield data for...


Akansake, D.Abidin, P.E.Carey, E.E.[Modeling the impact of sweetpotato weevils on storage root yield]Modeling the impact of sweetpotato weevils on storage root yield

Sweetpotato is a low-input crop with significant potential for improving public health and nutrition and developing food security in sub-Saharan Africa. This chapter examines the nutritional contribution made by OFSP (orange-fleshed sweetpotato) in poor rural communities in Malawi, Ghana, Nigeria...


Abidin, P.E.Carey, E.E.[Improving the breeding, cultivation and use of sweetpotato in Africa]Improving the breeding, cultivation and use of sweetpotato in Africa

Malnutrition, particularly vitamin A deficiency, is a major public health problem in many developing countries. This study investigated whether priming or self-generation of goals, or whether attention to instrumental or experiential goals together with use of a reminder condition or not, promote...


Lagerkvist, C.J.Okello, J.J.Adekambi, S.Kwikiriza, N.Abidin, P.E.Carey, E.E.[Goal-setting and volitional behavioural change: Results from a school meals intervention with vitamin-A biofortified sweetpotato in Nigeria]Goal-setting and volitional behavioural change: Results from a school meals intervention with vitamin-A biofortified sweetpotato in Nigeria
