    • Efects of silver nitrate on in vitro development of yam (Dioscorea rotundata Poir) plants 

      Oluwasegun, R.Y.; Uchendu, E.E.; Adeyemi, A.; Abberton, M.T. (2024-09-25)
      Yam (Dioscorea spp.) production is constrained by many factors including insufficient planting materials, diseases, and climate change. Plant tissue culture (PTC) offers practical solutions for rapid propagation of many plant types. However, ethylene buildup during PTC is a major challenge to in vitro plant growth and development. This study examined the effects of silver nitrate (AgNO3), a known ethylene action blocker on the in vitro growth and development of four accessions of D. rotundata in ...

    • The challenge of industrialization of a nature-based solution that allows farmers to produce aflatoxin-safe crops in various African countries 

      Kaptoge, L.; Ortega-Beltran, A.; Atehnkeng, J.; Konlambigue, M.; Kamau, J.W.; Bandyopadhyay, R. (2024-12-06)
      In sub-Saharan Africa (SSA), many crops are contaminated by Aspergillus section Flavi fungi with highly toxic, carcinogenic aflatoxins. This contamination has severe negative impacts on health, trade, income, and development sectors, hindering progress toward various objectives of most Sustainable Development Goals (SDGs), including SDG 2 – Zero Hunger and SDG 3 – Good Health and Wellbeing. Farmers, industries, and governments need sound aflatoxin management strategies to effectively limit aflatoxin ...

    • Exploring farmer’s assessment of soil quality and root yield in cassava-based cropping systems 

      Mesele, S.A.; Soremi, P.S.; Adigun, J.K. (2024-06-28)
      Nigeria. Data were collected on farmers’ demography, farming experience, criteria for selecting a site for cassava cultivation and preferences for those criteria, farmers’ methods of yield prediction and how it compares with the scientific approach, farmers’ agronomic knowledge and how it relates to the realities of climate change and soil fertility decline. The modal age class of the farmers is 45–55 years, and most of the farmers are male. The results show that farmers use a combination of soil ...

    • Signaling quality in informal markets. Evidence from an experimental auction in the Sahel 

      Ricker-Gilbert, J.; Moussa, B.; Abdoulaye, T. (2025-01)
      This study estimates the extent to which rural consumers in sub-Saharan Africa value quality signals about their food. We tested this by implementing an incentive-compatible Becker-Degroot Marschak auction among consumers in Niger and Northern Nigeria to estimate their willingness to pay (WTP) for cowpea (blackeyed pea) that was stored and sold in an improved grain storage bag that signaled unobservable quality in the form of insecticide-free grain. The improved bag had two inner layers of ...

    • Quantifying factors limiting soybean yield in Southern Africa: a yield gap decomposition 

      Omondi, J.O.; Chiduwa, M.S.; Kyei-Boahen, S.; Masikati, P.; Nyagumbo, I. (International Institute of Tropical Agriculture, 2024-12)
      Soybean production in Sub-Saharan Africa (SSA) is increasing as its demand for food, feed, cash, and soil fertility improvement soars. Yet, the difference between the smallholder farmers’ yield and either the attainable in research fields or the potential from crop models is large. Most of the reasons for the yield gap are known including low to non-application of appropriate fertilizers and inoculants, late planting, low plant populations, using recycled seeds, and poor crop management practices. ...

    • Control potential of multiple nucleopolyhedrovirus (SfMNPV) isolated from fall armyworm in Nigeria (West Africa) 

      Tepa-Yotto, G.; Douro Kpindou, O.; Koussihouede, P.S.; Adjaoke, A.; Winsou, J.K.; Tognigban, G.; Tamo, M. (2024-03-26)
      The fall armyworm (FAW) Spodoptera frugiperda (Lepidoptera, Noctuidae) has now become an invasive pest of global concern. The pest was first detected in Central and Western Africa in early 2016. Sustainable management options explored by stakeholders during early FAW invasion in Africa included the use of biopesticides and biological control. The current study aimed to compare the susceptibility of FAW larvae to SfMNPV with the assumption that the virus isolated from FAW populations in Africa has ...

    • Remotely sensed spectral indicators of bird taxonomic, functional and phylogenetic diversity across Afrotropical urban and non-urban habitats 

      Awoyemi, A.G.; Alabi, T.R.; Ibanez-Alamo, J.D. (2025-01)
      Urban areas are quickly expanding around the world, promoting deep changes in biodiversity. However, certain biogeographic realms, like the Afrotropics, are clearly understudied despite urbanization overlapping with their biodiversity hotspots. A commonly highlighted reason for the lack of information from the Afrotropics has been the logistical problem associated with data collection in the field. Recent advances in satellite remote sensing imagery offer an excellent opportunity to revert this ...

    • Development of standard operating protocol for measurement of cassava root mealiness 

      Osunbade, A.O.; Alamu, E.O.; Awoyale, W.; Adesokan, M.; Akinwande, B.; Adejuyitan, A.; Maziya-Dixon, B. (2024-07-27)
      One of the major attributes of boiled cassava roots is its ability to soften within a short period, otherwise known as mealiness. This study aimed to establish and validate standard operating procedures for assessing the mealiness of boiled cassava roots. Twenty cassava genotypes, including landrace and improved varieties, were selected for the protocol development, with an additional ten genotypes used for validation. Following cooking, the cassava roots were evaluated for hardness and work done ...

    • Early detection of plant virus infection using multispectral imaging and machine learning 

      Grieve, B.; Duffy, S.; Dallas, M.M.; Ascencio‑Ibanez, J.T.; Alonso-Chavez, V.; Legg, J.; Hanley-Bowdoin, L.; Yin, H. (2024-07-31)
      Climate change-resilient crops like cassava are projected to play a key role in 21st-century food security. However, cassava production in East Africa is limited by RNA viruses that cause cassava brown streak disease (CBSD). CBSD typically causes subtle or no symptoms on stems and leaves, while destroying the root tissue, which means farmers are often unaware their fields are infected until they have a failed harvest. The subtle symptoms of CBSD have made it difficult to study the spread of the ...

    • Delineation of tuber development in African yam bean (Sphenostylis stenocarpa (Hochst ex. A. Rich) Harms 

      Ojuederie, T.C. (University of Ibadan, 2021)
      African yam bean (AYB) belongs to the family Fabaceae. It is an orphan crop with so many potentials that have not been well utilised. It produces both edible seeds and tubers with high nutritional values. However, the crop is grown mainly for the seeds in West Africa, but the tubers are mainly consumed in East and Central Africa. The dual food advantage of AYB is yet to be fully tapped, due to the irregular tuberization in accessions. This study therefore characterised tuber development in AYB ...
