The sustainability of a groundnut plus maize rotation over 12 years on smallholder farms in the sub-humid zone of Zimbabwe
(Academic Journals, 2007)
An experiment was conducted on four smallholder farms and on-station in the sub-humid zone of northeast Zimbabwe for 12 years to assess how the rotation of groundnut with NPK-fertilized and unfertilized maize affected the ...
Diagnostic research to enable adoption of transgenic crop varieties by smallholder farmers in Sub-Saharan Africa
(Academic Journals, 2003)
Diagnostic research is important in helping to create an enabling environment for promising biotechnology products in smallholder agriculture, before rather than after release. The biotechnology products that now hold ...
Evaluation of the use of herbicide (Imazapyr) and fertilizer application in integrated management of Striga asiatica in maize in Malawi
(Academic Journals, 2007)
The parasitic weed species Striga asiatica (L.) Kuntze is one of major constraints in maize production in Malawi. Studies were conducted from 1999/2000 to 2001/2002 seasons to evaluate the effects of seed dressing with ...
Farmer perceptions on maize cultivars in the marginal eastern belt of Zimbabwe and their implications for breeding
(African Crop Science Society, 2006)
Productivity of maize ( Zea mays check for this species in other resources ) is low in the small-holder sector of Zimbabwe because the crop is grown under stress-prone environments and limited resources. The objective of ...
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 ...
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 ...
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 ...
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 ...
Selection for drought tolerance in two tropical maize populations
(African Crop Science Society, 2003)
Drought is a major factor limiting maize ( Zea mays check for this species in other resources L.) yield in much of the world. The need to breed maize cultivars with improved drought tolerance is apparent. This study compared ...
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 ...
