Soil fertility management research for the maize cropping systems of smallholders in Southern Africa: a review
This paper examines the implications of declining soil fertility for the maize-based cropping systems in southern and eastern Africa. A review of the importance of maize in the region is followed by a description of the ...
Research on soil fertility in Southern Africa: ten awkward questions
By raising important, sometimes ignored questions about research on soil fertility management in the subsistence, risk-prone maize-based cropping systems of sub-Saharan Africa, this paper seeks to improve the quality of ...
Soil fertility research for maize-based farming systems in Malawi and Zimbabwe
These proceedings of the Soil Fertility Research Network (Soil Fert Net) Results and Planning Workshop bring together forty papers on soil fertility research for maize-based farming systems in Malawi, Zimbabwe and beyond. ...
On-farm legume experimentation to improve soil fertility in the Zimuto communal area, Zimbabwe: farmer perceptions and feedback
Soil fertility is an important limiting factor for smallholder agriculture in southern Africa. In 1999-2002 research was undertaken to identify and evaluate legume technology options for soil fertility improvement within ...
Potential technology and research needs for rainfed maize production in drought prone environments of Southern Africa
In southern Africa, semi-arid areas (here simply defined as areas with less than 700 mm but more than 350 mm of rainfall per annum) can be found from around 100 m to over 1,400 m above sea level. The semi-arid areas most ...
Maize adaptive research: achievements and prospects in Southern Africa
In the last six to eight years, farming systems adaptive research has contributed much to the understanding of maize production constraints on smallholder farms in southern Africa. It has contributed less to the development ...
Targeting recommendations for small farmers: the role of economic factors in Zimbabwe and Swaziland
Natural conditions and major resource differences such as farm size are commonly used in on-farm research to define homogeneous 'recommendation domains' within which new technologies are tested. Successful trial results ...
The contribution of economic analysis in developing promising research agendas: a maize nitrogen x phosphorus trial in Zimbabwe
Maize accounts for 70% of Zimbabwe's cereal growing area. Its productivity, particularly in the communal areas, is limited by both soil and moisture constraints. Most soils in communal areas are coarse-textured sands derived ...
Chimanga cha makolo, hybrids and composites: farmers' adoption of maize technology in Malawi, 1989-90
During the 1989-90 and 1990-91 cropping seasons, researchers from CIMMYT and the Evaluation Units of the Malawian Ministry of Agriculture (MOA) collected data to profile farmers' adoption behavior and varietal choices, and ...
