Conservation agriculture systems for Malawian smallholder farmers: long term effects on crop productivity, profitability and soil quality
(Cambridge University Press, 2013)
Conservation agriculture (CA) systems are based upon minimal soil disturbance; crop residue retention and crop rotation and/or intercrop association are increasingly seen to recycle nutrients, increase yield and reduce ...
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 ...
On-farm evaluation of short-season sorghum and fertilizer for smallholder farmers in a semi-arid region of Zimbabwe
Three on-farm experiments were conducted during 1984-85, 1985-87 in Siabuwa, Zimbabwe to test 1) earlier maturing food sorghums with pearly white grain and 2) fertilizer application as possible solutions to production ...
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 ...
Response of four maize varieties to nitrogen at Lisungwi extension planning area, Mwanza, Malawi
Lisungwi Extension Planning Area (EPA) in Mwanza Rural Development Project (RDP) has insufficient rainfall for optimum maize growth. The soils are generally low in organic matter, nitrogen, phosphorus, and magnesium. Farmers ...
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 ...
The Fifth Regional Wheat Workshop for Eastern, Central, and Southern Africa and the Indian Ocean
(CIMMYT; CIDA, 1988)
Wheat and triticale have again become part of the agricultural practices of Malagasy farmers and production has increased in the last few years. However, two major wheat problems appeared in 1986: wheat rust and the ...
Wheat bibliography from Southern Africa: breeding, pathology and production research and extension literature
The impetus for this bibliography came as a guide to the Steering Committee of the Maize and Wheat Improvement Research Network for SADC (MWIRNET) to the published wheat research conducted in southern Africa. This type of ...
