    • Cost-effective cassava processing: case study of small-scale flash-dryer reengineering 

      Tran, T.; Abass, A.; Andrade, L.A.T.; Chapuis, A.; Precoppe, M.; Adinsi, L.; Bouniol, A.; Ojide, M.; Adegbite, S.A.; Lukombo, S.; Sartas, M.; Teeken, B.; Fotso Kuate, A.; Ndjouenkeu, R.; Moreno, M.T.; Belalcázar, J.; Lopez-Lavalle, L.A. (Springer, 2022)
      The development and scaling out of flash-dryer innovations for more efficient, small-scale production of high-quality cassava flour (HQCF) and starch is described. The diagnoses of cassava-processing SMEs (small and medium enterprises) revealed their energy expenditures for drying were considerably higher than those of large-scale industrial companies, which was mostly due to suboptimal design of flash-drying systems. As a result, small-scale production of cassava starch and HQCF often incurs high ...

    • A review of biotechnological approaches towards crop improvement in African yam bean (Sphenostylis stenocarpa Hochst. Ex A. Rich.) 

      Oluwole, O.O.; Aworunse, O.S.; Aina, A.I.; Oyesola, O.L.; Popoola, J.O.; Oyatomi, O.; Abberton, M.; Obembe, O. (2021-11)
      Globally, climate change is a major factor that contributes significantly to food and nutrition insecurity, limiting crop yield and availability. Although efforts are being made to curb food insecurity, millions of people still suffer from malnutrition. For the United Nations (UN) Sustainable Development Goal of Food Security to be achieved, diverse cropping systems must be developed instead of relying mainly on a few staple crops. Many orphan legumes have untapped potential that can be of ...

      Esuma, W.; Ozimati, A.; Kulakow, P.; Gore, M.A.; Wolfe, M.; Nuwamanya, E.; Egesi, C.; Kawuki, R.S. (2021-09)
      Global efforts are underway to develop cassava with enhanced levels of provitamin A carotenoids to sustainably meet increasing demands for food and nutrition where the crop is a major staple. Herein, we tested the effectiveness of genomic selection (GS) for rapid improvement of cassava for total carotenoids content and associated traits. We evaluated 632 clones from Uganda’s provitamin A cassava breeding pipeline and 648 West African introductions. At harvest, each clone was assessed for level of ...

    • The exploitation of orphan legumes for food, income, and nutrition security in sub-Saharan Africa 

      Popoola, J.O.; Aworunse, O.S.; Ojuederie, O.B.; Adewale, D.B.; Ajani, O.C.; Oyatomi, O.; Eruemulor, D.I.; Adegboyega, T.T.; Obembe, O. (2022)
      Poverty, food, and nutrition insecurity in sub-Saharan Africa (SSA) have become major concerns in recent times. The effects of climate change, drought, and unpredictable rainfall patterns threaten food production and sustainable agriculture. More so, insurgency, youth restiveness, and politico-economic instability amidst a burgeoning population requiring a sufficient and healthy diet remain front-burner issues in the region. Overdependence on only a few major staple crops is increasingly promoting ...

    • Arbuscular mycorrhizal fungi community composition, richness and diversity on enset (Ensete ventricosum (Welw.) Cheesman) in Ethiopia is influenced by manure application intensity in low‑input farming systems 

      Garo, G.; Van Geel, M.; Eshetu, F.; Swennen, R.; Honnay, O.; Vancampenhout, K. (2022)
      Aims In low-input agricultural systems, arbuscular mycorrhizal fungi (AMF) play a role in plant nutrition, protection and water use. Evaluating how agricultural practices affect the composition of AMF communities is therefore an important step towards sustainable intensification. We characterized the AMF communities in enset (Ensete ventricosum) roots in smallholder enset-based farming systems in south Ethiopia and assessed the effects of soil fertility management on those communities. Methods We ...

    • Situational analyses on cowpea value chain in Zambia: the case of an untapped legume 

      Mwila, N.M.; Munyinda, K.; Mwala, M.; Kamfwa, K.; Kambikambi, T.; Siyunda, A.; Sinyangwe, S.; Kanenga, K.; Alamu, E.O.; Rubaihayo, P. (2022-07-05)
      Cowpea (Vigna unguiculata (L.) Walp) is a vital legume crop for Zambia’s urban and rural households. The crop is an important legume used as human and animal food and as a component of the agricultural production system, which improves the fertility of many depleted soils because of its ability to fix atmospheric nitrogen. Government through the ministries of health and agriculture recommend its’ use. Despite the importance of cowpea in the nation, there is limited information on the crop along ...

    • Host status of Bambara groundnut accessions to Meloidogyne incognita using conventional screenhouse and novel seedling pouch methods 

      Ayeni, B.P.; Claudius-Cole, A.O.; Abberton, M.; Coyne, D. (2022-02-09)
      Bambara groundnut (Vigna subterranea) is an underexploited legume indigenous to sub-Saharan Africa with high protein content. Production constraints of Bambara groundnut include the root-knot nematodes (Meloidogyne spp.), which causes substantial losses that present an additional burden that growers need to manage. In this study we: i) assessed genetic resistance against Meloidogyne incognita in Bambara groundnut; and ii) evaluated an improved, more efficient screening method for Bambara. Fifty ...

    • Integrated management of Spodoptera frugiperda 6 years post detection in Africa: a review 

      Tepa-Yotto, G.; Chinwada, P.; Rwomushana, I.; Goergen, G.; Subramanian, S. (2022-08)
      The introduction of fall armyworm (FAW) Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) on the African continent has led to paradigm shifts in pest control in maize systems, occasioned by year-round populations. The discovery of resident parasitoid species adapting to the new pest significantly informed decision-making toward avoiding highly hazardous synthetic insecticides to control the pest. A number of biopesticides have shown promise against the fall armyworm, providing a new arsenal ...

      Amole, T.; Adekeye, A.; Bakare, B.; Meseka, S.K.; Mengesha Abera, W.; Menkir, A. (2022)
      The study evaluated the fodder potential of 42 promising drought-tolerant (DT) three-way cross maize (Zea mays L.) hybrids, 11 commercial hybrid checks, and 1 local variety check under irrigation. Agronomic and laboratory trials were conducted to determine their morphological traits and fodder potential. Hierarchical cluster analysis (HCA) to group cultivars into clusters is based on quantity, quality, and the combination of both variables. Selection of potential food-feed cultivars was based on ...

    • Sustainable management of transboundary pests requires holistic and inclusive solutions 

      Prasanna, B.M.; Carvajal-Yepes, M.; Kumar, P.L.; Kawarazuka, N.; Liu, Y.; Mulema, A.A.; McCutcheon, S.; Ibabao, X. (2022-06-06)
      Globalization and changing climates are aggravating the occurrence and impacts of transboundary pests, and driving the emergence of new threats. Most of the low- and middle-income countries in Africa, Asia and Latin America are not fully prepared in terms of surveillance, diagnostics, and deployment of plant health solutions due to several factors: adequate investment is lacking; knowledge is inadequate; and connections from the local to global, and global to local are insufficient. Effectively ...

    • Association mapping of plant sex and cross-compatibility related traits in white Guinea yam (Dioscorea rotundata Poir.) clones 

      Asfaw, A.; Mondo, J.; Agre, A.P.; Asiedu, R.; Akoroda, M.O. (2022-06-15)
      Background White Guinea yam (Dioscorea rotundata) is primarily a dioecious species with distinct male and female plants. Its breeding is constrained by sexual reproduction abnormalities, resulting in low success rates in cross-pollination. An accurate method for early detection of this plant’s sex and compatible fertile parents at the seedling stage would improve levels of cross-pollination success in breeding. We used the genome-wide association studies (GWAS) to dissect the molecular basis of ...

    • Indigenous African orphan legumes: potential for food and nutrition security in SSA 

      Abberton, M.; Paliwal, R.; Faloye, B.; Tchamba, M.; Azeez, M.; Oyatomi, O. (2022)
      In Sub-Saharan Africa (SSA), both crop production and the hidden hunger index (HHI, a combination of zinc, iron, and vitamin A deficiency), continue to be worse than the rest of the world. Currently, 31 out of 36 countries of SSA show the highest HHI. At the same time, several studies show climate change as a major constraint to agriculture productivity and a significant threat to SSA food security without significant action regarding adaptation. The food security of SSA is dependent on a few major ...

    • Inheritance of resistance to three endemic viral diseases of cowpea in Nigeria 

      Ogunsola, K.E.; Fatokun, C.; Boukar, O.; Kumar, P.L. (2022-06-22)
      Mosaic diseases, caused by bean common mosaic virus-blackeye cowpea mosaic strain (BCMV-BlCM), southern bean mosaic virus (SBMV), and cucumber mosaic virus (CMV), hamper the productivity of cowpea (Vigna unguiculata (L.) Walp.). Under single or mixed infections, these endemic viruses significantly reduce cowpea yield in sub-Saharan Africa. Planting resistant varieties is the most effective control method. Knowledge of the mode of inheritance of viral resistance is crucial in developing resistant ...

    • "Stop calling me a youth!": Understanding and analysing heterogeneity among Ugandan youth Agripreneurs 

      Turolla, M.; Swedlund, H.J.; Schut, M.; Muchunguzi, P. (2022-06-12)
      The African “youth” population is growing at a fast and steady pace, attracting attention from scholars, policymakers, and politicians. Yet, we know relatively little about this large and heterogeneous segment of the population. This paper presents data from 110 interviews and ten focus groups with youth engaged in commercial agriculture across all four regions of Uganda. Capitalising on this ethnographic data, we provide an analytical framework for studying complexity among the heterogeneous ...

      Sayadi Maazou, A.R.; Gedil, M.; Adetimirin, V.; Mengesha Abera, W.; Meseka, S.K.; Ilesanmi, O.J.; Agre, A.P.; Menkir, A. (2022-06-10)
      Background Temperate maize inbred lines with expired Plant Variety Protection Act certificates (Ex-PVP) are potential sources of desirable alleles for tropical germplasm improvement. Up to now, the usefulness of the Ex-PVP inbred lines as a potential source of novel beneficial alleles for Striga hermonthica resistance breeding to enhance genetic gain in tropical maize has not been reported. Results This study was thus conducted to characterize the combining ability of 24 Ex-PVP inbred lines ...

    • Bergmann's rule holds in birds inhabiting southern Guinea forests but not in the northern Savanna of Nigeria 

      Barshep, Y.; Awoyemi, A.G.; Abalaka, J.; Ottosson, U. (2022)
      The Bergmann’s rule predicts that in endotherms, body sizes will differ with respect to thermal gradients. Larger bodied individuals will inhabit colder environments while in warmer environments, individuals will be smaller-bodied. This hypothesis has been proved and disproved many times due to inconsistencies in body size differences along latitudinal gradients. We tested this hypothesis in 30 Afrotropical resident bird species inhabiting two vegetation types at different latitudes (southern ...

    • Improvements to cassava-maize intercropping systems in southern Nigeria 

      Nwokoro, C.C. (ETH Zurich, 2021)
      Cassava-maize intercrop is a traditional and the most popular cassava-based cropping system in southern Nigeria where farmers allocate > 60% of their farmland to intercropping in a typical cropping season. Besides that the system is ecologically adapted to the region, it facilitates a quick recovery from food and cash shortages at planting seasons caused by seed and cash investments in farming operations in every cropping season, .i.e., through food and income generated from maize harvest ~ 3 to ...
