  2. Morphological characterization of cacao cultivars in different socio-ecological settings of Ghana por Asare, E.

    Publicado 2022
    “…Cacao cultivars differed significantly in terms of these quantitative traits; pod wall thickness, the weight of fresh beans, number of beans and beans width have each P < 0.001 as well as beans thickness (P < 0.01), while pod weight and beans length were not significantly different. In conclusion, a comprehensive understanding of the morphological relationship among the cultivars studied alongside information on allelic richness could be valuable in selecting core parents and for future breeding purposes.…”

  3. Cassava-maize intercropping systems in southern Nigeria: radiation use efficiency, soil moisture dynamics, and yields of component crops por Nwokoro, C.C., Kreye, C., Necpalova, M., Adeyemi, O., Barthel, M., Pypers, P., Hauser, S., Six, Johan

    Publicado 2022
    “…Due to the popularity of cassava-maize intercropping and the food security and economic importance of both crops in Nigeria, we investigated options to improve interception of photosynthetically active radiation (IPAR), radiation use efficiency (RUE), soil moisture retention, and yields of cassava and maize in cassava-maize intercropping systems in 8 on-farm researcher-managed multi-location trials between 2017 and 2019 in different agro-ecologies of southern Nigeria. Treatments were a combination of (1) maize planting density (low density at 20,000 maize plants ha-1 versus high density at 40,000 maize plants ha-1, intercropped with 12,500 cassava plants ha-1); (2) fertilizer application and management targeting either the maize crop (90 kg N, 20 kg P and 37 kg K ha-1) or the cassava crop (75 kg N, 20 kg P and 90 kg K ha-1), compared with control without fertilizer application. …”

  5. Modelling crop-livestock systems for achieving food security and increasing production efficiencies in the Ethiopian highlands por Amede, Tilahun, Delve, Robert J.

    Publicado 2008
    “…Groups I and III were highly food deficit from their own farms, with production covering less than seven months per year and fulfilling <50% of the recommended daily allowances (RDA) for human nutrition. Using a linear programming optimization model, it was possible to fulfil the RDA of Group I by reallocating the cropping area of maize, sweet potato, coffee and wheat to potato, enset and kale in proportions of 50, 29 and 15%, respectively. …”
