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 ...
Comparative economics of maize production in risky environments in Zimbabwe
Planting strategies of smallholder farmers are examined in two contrasting study areas in Zimbabwe, Mangwende (sub-humid, natural region II) and Mudzi (semi-arid, natural region IV). to show that farmers regard maize as a ...
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 ...
Soil fertility network for maize-based farming systems: report of the period 1 October 1994 to 30 September 1995
The goal of the Network is to help smallholder farmers in Malawi and Zimbabwe produce higher, more sustainable and profitable yields from their dominant maize-based cropping systems. The Network aims to achieve that through ...
Simulating nitrogen fertilizer response in low-input farming systems of Malawi
This paper reports on the validation of the Agricultural Production Systems Simulator (APSIM) model for simulating the response of maize to N fertilizer in low-input maize production systems in Malawi and Zimbabwe, with a ...
Grain legumes and green manures for soil fertility in Southern Africa: taking stock of progress
(CIMMYT; Soil Fert Net, 2003)
This conference on the soil fertility benefits from green manures and grain legumes brought together 56 participants from Malawi, Zambia, Zimbabwe and Mozambique, along with some further key presenters from Ethiopia, Kenya ...
Extent and causes of low yield in maize planted late by smallholder farmers in sub-humid areas of Zimbabwe
Diagnostic work was undertaken during 1987-91 to determine the area of maize planted late by smallholder farmers in sub-humid (Natural Regions 2 and 3) communal areas of Zimbabwe, the grain yield losses encountered, and ...
