Crop simulation models can accurately predict yield with a priori knowledge of the soil properties and crop management practices. Generation of new information through traditional agronomic research practices is not sufficient to meet the needs for new agro-technologies and they are generally...
Download PDF ↓Maize is an important staple and cash crop in Zambia. Abiotic and biotic stress conditions, particularly low soil fertility (low nitrogen) and grey leaf spot(Cercospora zeae- maydis), reduce maize yields. Most varieties developed by the Zambian National Maize Programme have neither resistance to...
