    • Farmers' willingness to invest in mechanized maize shelling and potential financial benefits: evidence from Tanzania 

      Kotu, B.H.; Manda, J.; Mutungi, C.; Fischer, G.; Gaspar, A. (2023)
      Sub-Saharan Africa has the least mechanized agriculture in the world due to various reasons including low effective demand at farm level, low policy attention, and ineffective mechanization strategies. However, the situation has changed since recently in favor of mechanization while limited empirical evidence is available on how mechanization can be enhanced among smallholder farmers. In this study, we explore farmers' willingness to invest in mechanization services by considering the group business ...

    • Maize productivity and household welfare impacts of mobile money usage in Tanzania 

      Kilombele, H.; Feleke, S.; Abdoulaye, T.; Cole, S.M.; Sekabira, H.; Manyong, V. (2023-01-31)
      This study examined the determinants and impacts of mobile money (MM) usage on maize productivity and poverty likelihood (i.e., the probability of a household falling below the international poverty line at USD 1.9 per capita per day) in the Mbeya Region, Tanzania. The analysis was conducted using the endogenous switching regression (ESR) model on data from a random sample of 1310 households selected from seven districts in the region. Results of the ESR estimation show that MM usage is strongly ...

    • Diallel analysis of soybean (Glycine max L.) for biomass yield and root characteristics under low phosphorus soil conditions in western Ethiopia 

      Abebe, A.T.; Adewale, S.; Chigeza, G.; Derera, J. (2023)
      Combining ability studies under low soil P conditions provides useful information on the inheritance of important traits to improve soybean for low P tolerance. The study aimed at determining the combining ability and gene actions of biomass yield and root traits in soybean under low phosphorus conditions. Nine parental genotypes and their 36 half diallel F2/F3 progenies were evaluated at two locations in Ethiopia on soils of low P availability. Highly significant (P<0.01) general combining ability ...

    • Elaborating institutional arrangements to better enhance sustainable crop intensification in Uganda: a farmers’ perspective 

      Pali, P.N.; Tebeka, Y.A.; Schut, M.; Mangheni, M.N.; Wairegi, L.W.; Manyong, V.; Van Asten, P.J.A. (2023-02)
      Weak and inefficient institutional arrangements have been identified as a major cause of the slow pace of agricultural growth in developing countries. Institutions – the humanly devised constraints that shape human interaction – play a significant role in Sustainable Crop Intensification (SCI) in Uganda. This study uses farmers' perceptions to assess institutions and their roles in SCI. We collected data from 135 rice and potato-producing households in Eastern and Southwestern regions of Uganda ...

    • Potential of Cameroon-indigenous isolates of the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae as microbial control agents of the flea beetle Nisotra uniformis 

      Niyibizi, I.A.B.; Hanna, R.; Kekeunou, S.; Membang, G.; Fiaboe, K.; Mahot, H.C.; Abang, A.F.; Kumar, P.L.; Fotso Kuate, A. (2023)
      The flea beetle Nisotra uniformis Jacoby is a widespread pest of malvaceous crops for which synthetic chemical insecticides remain the principal control tool, particularly in sub-Saharan Africa. With the ultimate aim of developing a microbial alternative for N. uniformis control, we conducted laboratory experiments (25 ± 1°C; 70 - 80% RH) to evaluate the biological attributes of three Cameroonian isolates of the entomopathogenic fungi Beauveria bassiana (Balsamo-Crivelli) Vuillemin and Metarhizium ...

    • Gender-disaggregated consumer testing and descriptive sensory analysis of local and new yam varieties 

      Effah-Manu, L.; Wireko-Manu, F.D.; Agbenorhevi, J.K.; Maziya-Dixon, B.; Oduro, I. (2023-01-25)
      Gender-disaggregated sensory evaluation has become an essential element that could enhance breeding activities by increasing the adoption of new varieties. The effect of age, sex and geographical location on descriptor preferences for boiled and pounded yam were studied using descriptive and consumer testing. Attributes with definitions and measurement scales were used to generate lexicons for boiled and pounded yam. Analytical tools employed for the inferential statistics were the independent ...

    • Spatial modelling indicates Striga seedbank density dependence on rainfall and soil traits in the savannas of northern Nigeria 

      Aliyu, K.T.; Lado, A.; Hussaini, M.A.; Kamara, A.; Musa, S.A.; Dawaki, M.U.; Suleiman, M.S.; Bello, T.T.; Fagge, A.; Isa, H.M.; Ibrahim, H. (2023-02-13)
      Striga is one of most notorious weeds devastating crop production in the dry savannas of northern Nigeria. The weed attacks most cultivated cereals and legumes with crop losses as high as 100% when no control measure is employed. Studies conducted in the dry savannas of Nigeria indicated that Striga seedbank is strongly related to soil and climate properties. This study was conducted to model Striga hermonthica seedbank zones in the dry savannas of Nigeria based on soil and climate properties of ...

    • Identification of a major QTL-controlling resistance to the subtropical race 4 of Fusarium oxysporum f. sp. cubense in Musa acuminata ssp. malaccensis 

      Chen, A.; Sun, J.; Martin, G.; Gray, L.A.; Hřibová, E.; Christelova, P.; Yahiaoui, N.; Rounsley, S.; Lyons, R.; Batley, J.; Chen, N.; Hamill, S.; Rai, K.; Coin, L.; Uwimana, B.; D’hont, A.; Doležel, J.; Edwards, D.; Swennen, R.; Aitken, E.A.B. (2023-02-09)
      Vascular wilt caused by the ascomycete fungal pathogen Fusarium oxysporum f. sp. cubense (Foc) is a major constraint of banana production around the world. The virulent race, namely Tropical Race 4, can infect all Cavendish-type banana plants and is now widespread across the globe, causing devastating losses to global banana production. In this study, we characterized Foc Subtropical Race 4 (STR4) resistance in a wild banana relative which, through estimated genome size and ancestry analysis, was ...

    • Variability and genetic merits of white Guinea yam landraces in Nigeria 

      Agre, A.P.; Edemodu, A.; Obidiegwu, J.; Adebola, P.O.; Asiedu, R.; Asfaw, A. (2023-02-06)
      Introduction: Landraces represent a significant gene pool of African cultivated white Guinea yam diversity. They could, therefore, serve as a potential donor of important traits such as resilience to stresses as well as food quality attributes that may be useful in modern yam breeding. This study assessed the pattern of genetic variability, quantitative trait loci (QTLs), alleles, and genetic merits of landraces, which could be exploited in breeding for more sustainable yam production in Africa. ...

    • Banana bunchy top virus threat to African bananas 

      Kumar, P.L. (Food and Agriculture Organization of the United Nations, 2022-09-07)
      The banana bunchy top virus (BBTV) is threatening livelihoods and banana biodiversity in sub-Saharan Africa. Since the first report in the 1960s, the virus has spread to 17 countries, eight of those in the last decade, including a recent spread in Uganda and Tanzania. In the "2022 International Plant Protection Convention Regional Workshop for Africa," organized by the FAO-IPPC, the African Union-Inter-African Phytosanitary Council (AU-IAPSC), the Plant Protection Organization of Kenya (KEPHIS), ...

    • Bias correction of daily chirps-V2 rainfall estimates in Ghana 

      Johnson, R. (Kwame Nkrumah University of Science and Technology, 2022-10)
      A wide range of economic sectors in the Ghana, including agriculture, health care, and energy, heavily rely on climate data; as a result, having access to reliable climate data is crucial for research and economic growth yet rainfall gauge data in Ghana scarcely available, therefore, researchers tend to depend on satellite estimates for hydrological studies and impact assessments. However, biases in satellite rainfall estimates and the ability for these rainfall products to effectively capture ...

      Vayssieres, J.; Cherasse, S.; Page, N.; Laplace, D.; Beauchene, J.; Gourmel, C.; Denis, S.; Pinault, D.; Rhino, B.; Bertrand, M.; Germain, J.; Goergen, G.; Le Bellec, F. (2022-09)
      Contexte - En septembre 2014, l’espèce invasive, Rastrococcus invadens Williams (Hemiptera : Pseudococcidae) a été détectée à Cayenne (Guyane), puis rapidement identifiée par le LSV-Anses. C’est le premier signalement de la cochenille sur le continent sud-américain. À la demande du ministère de l’Agriculture, une mission a été réalisée par le Centre de coopération internationale en recherche agronomique pour le développement (Cirad) fin 2016 afin de définir la gamme des plantes-hôtes de R. invadens, ...
