Crop model usefulness in drylands of southern Africa: an application of DSSAT
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Nkulumo Zinyengere --- Climate System Analysis Group, Department of Environmental and Geographical Science, South Africa Olivier Crespo --- Climate System Analysis Group, Department of Environmental and Geographical Science, South Africa Sepo Hachigonta --- Food Agriculture and Natural Resources Policy Analysis Network, South Africa Mark Tadross --- United Nations Development Programme – Global Environment Facility, South AfricaCrop models are useful tools for simulating impacts of climate and agricultural practices on crops. Models have to demonstrate the ability to simulate actual crop growth response in particular environments before application. Data limitations in southern Africa frequently hinder adequate... -
Calibration and evaluation of a CROPGRO Perennial Forage Model for Brachiaria humidicola yield simulation under future climate in subhumid environments of Ethiopia
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Fantahun Dereje --- Wallaga University, Ethiopia Ashenafi Mengistu --- Addis Ababa University, Ethiopia Diriba Geleti --- Ethiopian Institute of Agricultural Research, Ethiopia Fekede Feyissa --- Ethiopian Institute of Agricultural Research, Ethiopia Diriba Diba --- Wallaga University, Ethiopia Diego Pequeno --- , Mexico Buzunesh Tesfaye --- Wallaga University, EthiopiaCrop simulation models can be employed to assess the impacts of climate change and aid in strategic planning and decision making regarding forage strategies. This study focused on calibrating and assessing the performance of the CROPGRO Perennial Forage Model in... -
Integrating seasonal forecast information with crop models to inform decision making in small-scale farming under climate variability
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Siyabusa Mkuhlani --- Climate Systems Analysis Group, Environmental and Geographical Science Department, Faculty of Science, University of Cape Town, South Africa Farirai Rusere --- University of the Witwatersrand, South Africa Nkulumo Zinyengere --- World Bank Group, USA Olivier Crespo --- Climate Systems Analysis Group, Environmental and Geographical Science Department, Faculty of Science, University of Cape Town, South AfricaIntegrating seasonal forecast information and crop models has the potential to inform farm management decisions under climate variability. The study assessed the feasibility of integrating seasonal forecast information into crop models for decision making in small-scale farming conditions in South...
