Change in crop management strategies could double the maize yield in Africa
Eyshi Rezaei, Ehsan; Gaiser, Thomas (2017-07)Change in cropping practices is required to address the food security issues in Africa. Yet, testing of the performance of such changes, in particular at large scales, often needs significant investments. Crop models are ... -
Doubler le rendement du maïs en afrique grâce à une meilleure gestion des cultures: Résultats d’un modèle de simulation de culture pour éclairer les politiques et la recherche
Baraké, Evelyn; Eyshi Rezaei, Ehsan; Gaiser, Thomas (2018-01)Malgré l’importance du maïs en tant que culture de base pour la sécurité alimentaire en Afrique, les rendements dans la région sont très faibles par rapport au reste du monde. Pour répondre à la demande croissante, il est ... -
Doubling the Maize Yield in Africa through better Crop Management: Results from a crop simulation model to inform policy and research
Baraké, Evelyn; Eyshi Rezaei, Ehsan; Gaiser, Thomas (2018-01)Despite the importance of maize as a staple crop for food security in Africa, yields in the region are very low in comparison to the rest of the world. To keep up with growing demand, increasing the productivity of Africa’s ... -
Evaluating rice performance in contrasting East African wetlands using an experimental and modelling approach
Grotelüschen, Kristina (2021-10-07)Rice (<em>Oryza</em> spp.) has become an important staple food and cash crop across East Africa, and is now playing a pivotal role in regional food security and national economies. Since regional rice yields remain low, ... -
Genome Wide Association Study and Genomic Selection Models for Nitrogen Use Efficiency in Bread Wheat
Sadeqi, Mohammad Bahman (2024-05-17)Nitrogen (N) as an essential element in the structure of proteins, nucleic acids and chlorophyll plays an important role in grain yield. Nitrogen fertilizer, which is most commonly used in cereal production, is necessary ... -
