    • Agronomic performance and yield stability of extra-early maturing maize hybrids in multiple environments in the Sahel 

      Konate, L.; Badu-Apraku, B.; Coulibaly, M.; Menkir, A.; Laouali, M.N.; Meseka, S.K.; Mengesha Abera, W. (2023-09)
      Frequent occurrence of drought, heat, low soil fertility and Striga infestation are the main stress factors reducing maize yield in the Sahel. Adoption of stable multiple stress tolerant maize cultivars in the region is crucial for achieving food security. However, selection of a stable high yielding cultivar is complicated by genotype × environment interaction (GEI) due to differential responses to growing conditions. Eleven extra-early maturing multiple-stress tolerant maize hybrids and two ...

    • Closing the crop yield gap between organic and conventional farming systems in Kenya: Long-term trial research indicates agronomic viability 

      Bautze, D.; Karanja, E; Musyoka, M.; Ruegg, J.; Goldmann, E.; Kiboi, M.; Kampermann, I.; Cotter, M.; Riar, A.; Matheri, F.; Mwangi, E.; Mucheru-Muna, M.; Wambui, H.; Anyango, J.J.; Ndung’u, S.; Tanga, C.; Fiaboe, K.K.M.; Mbaka, J.; Muriuki, A.; Kamau, D.; Adamtey, N. (2024-12)
      The production gap between current and attainable yields is highest on Africa`s smallholder farms, and some studies indicate that they might not benefit from the yield gains offered by conventional farming. Simultaneously, alternative farming systems like organic provide biodiversity and soil fertility advantages, but their ability to produce sufficient food is still under debate. Additionally, comparative data on the productivity of organic versus conventional in tropical regions are scarce or ...

      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 ...
