Genotype x environment interaction and selection for drought adaptation in sweetpotato (Ipomoea batatas [L.] Lam.) in Mozambique

Sweetpotato is grown throughout the year in Mozambique but drought affects storage root yield and biomass productivity. The objectives of this research were to estimate the impact of genotype × environment interactions (G × E) in sweetpotato and select genotypes based on drought indices such as geometric mean, percent yield reduction, drought sensitivity index …

Determining paternity in polyploids: Hexaploid simulation studies

The breeding of new sweetpotato varieties is a highly inefficient process, confounded by incompatibility, poor fertility, open-pollination and hexaploidy. Upwards of 12–20 lines are combined in open pollinated nurseries based on horticulturally important characteristics. After several years of selection most progeny can be traced back to just 3 or 4 …

Planning an integrated agriculture and health program and designing its evaluation: Experience from Western Kenya

  Multi-sectoral programs that involve stakeholders in agriculture, nutrition and health care are essential for responding to nutrition problems such as vitamin A deficiency among pregnant and lactating women and their infants in many poor areas of lower income countries. Yet planning such multi-sectoral programs and designing appropriate evaluations, to respond to different …

Farmer-led Seed Enterprise Initiatives to Access Certified Seed for Traditional African Vegetables and its Effect on Incomes in Tanzania

Farmers need access to certified seed stocks for efficient production of traditional African vegetable seed. However, access to quality certified seed is constrained by several factors. Primary data from four selected regions of Tanzania was analyzed to examine the causal linkages among traditional African vegetable farmers’ decisions to participate in …

Quality attributes of sweet potato flour as influenced by variety, pretreatment and drying method

The effect of pretreatment methods (soaking in water, potassium metabisulphite solution, and blanching) and drying methods (sun and oven) on some quality attributes of flour from ten varieties of sweet potato roots were investigated.The quality attributes determined were chemical composition and functional properties. Data obtained were subjected to descriptive statistics, …

Effect of frying temperature and time on composition and sensory quality of sweet potato crisps

Fried products have been found to be among the sweet potato products that are not only capable of increasing the utilization of sweet potato in Nigeria, but also have high commercial potential. It is important to establish frying conditions for use by emerging small to medium scale processors that will …

Iron Bioavailability and Provitamin A from Sweet Potato- and Cereal-Based Complementary Foods

Iron and vitamin A deficiencies in childhood are public health problems in the developing world. Introduction of cereal-based complementary foods, that are often poor sources of both vitamin A and bioavailable iron, increases the risk of deficiency in young children. Alternative foods with higher levels of vitamin A and bioavailable …

Implementation of Multiple Irish Aid-Funded Orange Flesh Sweet Potato Projects

Biofortification of sweetpotatoes is a promising and sustainable agricultural approach to reduce vitamin A deficiency (VAD), particularly in remote areas where individuals have limited access to commercial markets and mainly rely on household-produced crops. Due to its large genetic variability, its favorable growing characteristics, and the high consumption in remote …

Effect of maize intercrop plant densities on yield and β-carotene contents of orange-fleshed sweetpotatoes

Despite efforts to demonstrate the value of orange-fleshed sweetpotato (OFSP) (Ipomoea batatas L.) and quality protein maize (Zea mays L.) in combating vitamin A and protein malnutrition, small land holdings by rural poor farmers still limit the crops’ overall production in Africa. As such, intercropping and optimum plant density in …
