Allelopathic effect of sweetpotato (Ipomoea batatas) cultivars on certain weed and vegetable species
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C.F. Reinhardt --- Department of Plant Production, Republic of South Africa Ruth Meissner --- Department of Plant Production, Republic of South Africa P.C. Nel --- Department of Plant Production, Republic of South AfricaA glasshouse study was conducted to determine the allelopathic potential of sweetpotato (Ipomoea batatas (L.) Lam.) cultivars Bosbok, Brandal and Koedoe. Nine indicator plants, three weeds: yellow nutsedge (Cyperus esculentus L.), purple nutsedge (Cyperus rotundus L.) and common pigweed (Amaranthus... -
Phenotypic characterisation of sweetpotato genotypes grown in East and Central Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Rukundo Placide --- African Centre for Crop Improvement, South Africa Hussein Shimelis --- African Centre for Crop Improvement, South Africa Mark Laing --- African Centre for Crop Improvement, South Africa Daphrose Gahakwa --- Rwanda Agriculture Board, RwandaIdentification of genetic variability and interrelationships among germplasm collections is fundamental to select parents with complementary traits for plant breeding programmes. The aim of this study was to characterise and identify breeding parents among 54 sweetpotato genotypes grown in Rwanda,... -
Assessment of sweetpotato farming systems, production constraints and breeding priorities in eastern Tanzania
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Stephan Ngailo --- Sugarcane Research Institute, United Republic of Tanzania Hussein A Shimelis --- African Center for Crop Improvement, University of KwaZulu-Natal, South Africa Julia Sibiya --- African Center for Crop Improvement, University of KwaZulu-Natal, South Africa Kiddo Mtunda --- Sugarcane Research Institute, United Republic of TanzaniaSweetpotato is an important food security crop in Tanzania. The crop is grown under diverse farming systems with very low yields. The objective of this study was to assess the present sweetpotato farming systems, farmers’ preferences, production constraints and breeding... -
Pre-harvest Curing: Effects on Skin Adhesion, Chemical Composition and Shelf-life of Sweetpotato Roots under Tropical Conditions
Item type: Journal Article • Journal: East African Agricultural and Forestry Journal • Authors: Aditya Parmar --- Department of Agricultural and Biosystems Engineering, Germany Sascha M. Kirchner --- Department of Agricultural and Biosystems Engineering, Germany Barbara Sturm --- Department of Agricultural and Biosystems Engineering, Germany Oliver Hensel --- Department of Agricultural and Biosystems Engineering, GermanyExcoriation (skinning injury) is a serious post-harvest problem for sweetpotato roots. In industrialized countries, sweetpotatoes are exposed to post-harvest curing to facilitate skin toughening and wound healing. However, in developing regions, such a practice is barely undertaken. Pre-harvest curing (PHC),... -
Improving productivity of orange-fleshed sweetpotato (Ipomoea batatas) through intercropping with legumes and moderate phosphorus application
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Eliah Munda --- International Potato Center, Mozambique Petrus J Pieterse --- Department of Agronomy, South Africa Maria I Andrade --- International Potato Center, Mozambique Godwill S Makunde --- International Potato Center, Mozambique Engil I Pereira --- School of Earth, Environmental, and Marine Sciences, USASweetpotato yield is adversely affected by poor soil fertility in Mozambique where access to inorganic fertilisers is lacking. The objective of the study was to evaluate the effectiveness of intercropping sweetpotato with groundnut and soybean at various phosphorus (P) fertilisation... -
Adoption of dual-purpose sweetpotato varieties under partial population exposure in Rwanda: Insights from an African plant breeding programme
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Gideon Danso-Abbeam --- , South Africa Lloyd J.S. Baiyegunhi --- , South Africa Mark D. Laing --- , South Africa Hussein Shimelis --- , South AfricaAs part of the Green Revolution, plant breeding programmes such as the African Centre for Crop Improvement have trained scientists to breed crop varieties in Africa to address the challenges of low productivity. However, exposure to and adoption of these... -
Yield, nutritional composition, and consumer acceptability of sweetpotato cultivars cultivated with soil amendments in the Middleveld of Eswatini
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Samuel Kofi Tutu --- , Eswatini Henry R Mloza Banda --- , Eswatini Cinisani Tfwala --- , EswatiniUncertainties about the effects of nutrient amendment on the culinary attributes of sweetpotato have limited fertiliser use in Eswatini. The study was carried out at a moist and dry location of Eswatini to investigate the culinary and nutritional attributes of... -
Consumer acceptability of fried chips made from South African sweet potato cultivars
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: SM Laurie --- , South Africa WM Mphela --- , South AfricaIn South Africa, the processing of sweet potatoes has a high potential for economic gain, therefore, chips were prepared from six sweet potato cultivars with varying flesh colours for consumer preference evaluation. Scoring was based on colour, crispness, taste and... -
Does vitamin A rich orange-fleshed sweetpotato adoption improve household level diet diversity? Evidence from Ghana and Nigeria
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Souleimane Adeyemi Adekambi --- University of Parakou (UP), Parakou Julius Juma Okello --- , Uganda Jan Low --- , Kenya Putri Ernawati Abidin --- , Ghana Edward Carey --- , GhanaPromoting the consumption of locally available food crops such as orange-fleshed sweetpotato (OFSP) that are rich in beta carotene, a precursor for vitamin A, has been shown to be a highly effective means of fighting against vitamin A deficiency at...
