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 ...

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 ...

Using innovation platforms to scale out soil acidity-ameliorating technologies in Dedza district in central Malawi
(Academic Journals, 2012)
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 ...

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 ...
Article
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 ...
Article
Drivers of improved maize variety adoption in drought prone areas of Malawi
(Academic Journals, 2012)
This study identifies the determinants of adoption and adoption-intensity of improved maize varieties in Malawi. We estimated a double hurdle model based on household-level survey data collected in the districts of Balaka ...
Article
An appraisal of farmer variety selection in drought prone areas and its implication to breeding for drought tolerance
(Canadian Center of Science and Education, 2012)
Maize production and productivity among small scale farmers of southern Africa is limited mainly by drought and low soil fertility. This study aimed at assessing how farmers prioritize selection of varieties for planting ...
Article
Determination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines
(Gorgan University of Agricultural Sciences, 2012)
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maize production in sub-Saharan Africa. Varying levels of tolerance to Striga attack have been identified and exploited in breeding programs of several ...
