Twenty-five years of research on women farmers in Africa: Lessons and implications for agricultural research institutions -- With an annotated bibliography
Based on an extensive review of the literature on women farmers in Africa, this paper explores the potential reasons why women farmers have not adopted improved maize technologies and discusses the implications for ...
Maize-based conservation agriculture systems in Malawi: Long-term trends in productivity
In Malawi and throughout much of Africa, maize yields have declined over the past several decades due to continuous cultivation, often in monocropping with little or no inputs. As a result, soil degradation has been ...
Soil fertility management effects on maize productivity and grain zinc content in smallholder farming systems of Zimbabwe
Background and aims: Low soil zinc (Zn) threatens crop production and food nutrition in most cereal-based cropping systems in Africa. Agronomic management options that include farmers' locally available organic nutrient ...
Using innovation platforms to scale out soil acidity-ameliorating technologies in Dedza district in central Malawi
Soil acidity is a serious constraint in crop production in some parts of Malawi, particularly in high rainfall and high altitude areas. A learning platform was established in Bembeke Extension Planning Area (EPA) (14¡ã ...
