The contribution of economic analysis in developing promising research agendas: a maize nitrogen x phosphorus trial in Zimbabwe
(CIMMYT, 1990)
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
(CIMMYT, 1992)
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 ...

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 ...

Maize adaptive research: achievements and prospects in Southern Africa
(CIMMYT, 1990)
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 ...

Efficiency of managed-stress screening of elite maize hybrids under drought and low-N for yield under rainfed conditions in Southern Africa
(Crop Science Society of America (CSSA), 2012)
Maize (Zea mays L.) yields in southern Africa are low, due largely to drought and low-N stress. Selection of stress-tolerant genotypes by CIMMYT is conducted indirectly under managed stress conditions, although the selection ...

Bt-transgenic maize does not deter oviposition by two important African cereal stem borers, Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae)
(FacT Limited, 2008)
Objective: To assess Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) ovipositional responses on Bt (Event 216, containing the Cry1Ab gene) and isogenic non-Bt (CML ...

Experiences in effective communication on transgenic technology in Africa - the case of the insect resistant maize for Africa (IRMA) project
(Academic Journals, 2011)
The Insect Resistant Maize for Africa (IRMA) Project, aimed to improve food security through developing and deploying locally adapted stem borer resistant maize varieties using both conventional and biotechnology mediated ...
Article
Molecular characterization of diverse CIMMYT maize inbred lines from eastern and southern Africa using single nucleotide polymorphic markers
(BioMed Central, 2012)
Background: Knowledge of germplasm diversity and relationships among elite breeding materials is fundamentally important in crop improvement. We genotyped 450 maize inbred lines developed and/or widely used by CIMMYT ...

Developing Bt maize for resource-poor farmers - Recent advances in the IRMA project
(Academic Journals, 2005)
This paper presents an overview of the advances in the IRMA project, which develops insect resistant maize varieties for resource-poor farmers, using both conventional breeding and genetic engineering. The project started ...

Impediments to new improved maize variety testing and release in selected countries in Sub-Saharan Africa
(David Publishing, 2010)
Before farmers can benefit from new improved maize varieties with novel genetic information, new maize varieties have to undergo performance testing, registration and approval. The registration procedures require that new ...
