    • Effect of organic amendment on soil carbon dynamics in agricultural ecosystems 

      Hamamoto, T. (Hokkaido University, 2020-03-25)
      Soil carbon (C) contents and dynamics are important in the maintenance of health soils. Organic amendments (e.g. crop residue and organic manure) are known as materials to increase soil C. The degradation of organic amendments and physical disturbance of soils, performed by the fauna, can alter soil microbial community, and thus influence rates of the C cycles. However, little is known about the interaction between different soil biological communities (i.e. soil fauna and microbes) regarding soil ...
    • Equal and inclusive opportunity to access and use of ICT-based crop extension services for farm-level actors in Rwanda: a case study of the ICT4BXW project 

      Blom, F. (Wageningen University and Research Center, 2020-03-31)
      All farmers around the world have a need for information. Information communication technology (ICT) could make access to information easier (Palumbo, 2013) (Aker & Mbiti, 2010) (van Winden, 2011). Others do however claim that the use of ICT excludes certain users from accessing information (Diga, Fortune, & Plantinga, 2013) (Njoki & Wabwoba, 2014) (Waugaman, 2016). Not only the use of ICT but also the design of the ICT platform could exclude users from access to information (Clarkson, Dong, & ...

      Bello, T.T. (North-West University, 2020-05)
      Watermelon is increasingly produced and consumed in Nigeria and sub-Saharan Africa (SSA). However, limited information exists regarding the nematode fauna associated with the crop. Therefore, the overall aim of this study was to determine the nematode assemblages associated with watermelon, to investigate the reproduction potential of populations of the predominant plant-parasitic nematodes identified and to assess the host status of commercially available cultivars in south-west Nigeria to the ...
    • Site-specific nutrient management advice and agricultural intensification in maize-based systems in Nigeria 

      Oyinbo, O. (Katholieke Universiteit Leuven, 2019-12)
      Despite the potentially large gains from intensification and agricultural productivity growth in Sub-Saharan Africa (SSA), yields of staple crops, such as maize are far below attainable yields. Depletion of soil fertility associated with low and inappropriate use of nutrients play a crucial role in this. Yet, fertilizer use is low in SSA, which partly relates to information constraints. Relaxing such constraints via agricultural extension interventions is expected to produce positive outcomes but ...
    • Assessing the effect of the plant growth promoting fungi Trichoderma asperellum in banana (Musa spp.): evaluation under greenhouse conditions 

      Van den Bergh, A. (Katholieke Universiteit Leuven, 2019-06)
      Bananas (Musa spp.) are one of the most important crops in the global food crop industry, the second most important fruit crop and an important staple crop around the world. Due to the increased trend in global population, a raise in the intensity in crop productivity is needed. The use of plant growth-promoting microorganisms (PGPM) could be an alternative to improve the stress-tolerance and productivity of crops, thus, reducing the amount of chemical pesticides and fertilizers needed. Trichoderma ...

    • Taro in west Africa: status, challenges, and opportunities 

      Oladimeji, J.J.; Kumar, P.L.; Abe, A.; Vetukuri, R.R.; Bhattacharjee, R. (2022-09-01)
      Taro is an ancient nutritional and medicinal crop woven into the fabric of the socio-economic life of those living in the tropics and sub-tropics. However, West Africa (WA), which has been a major producer of the crop for several decades, is experiencing a significant decline in production as a result of taro leaf blight (TLB), a disease caused by Phytophthora colocasiae Raciborski. A lack of research on taro in WA means that available innovative technologies have not been fully utilized to provide ...
