Detection of genetic integrity of conserved maize (Zea mays L.) germplasm in genebanks using SNP markers
Twenty maize landrace accessions regenerated and conserved in five maize genebanks were investigated for genetic integrity using 1,150 Single Nucleotide Polymorphisms (SNPs) and 235 SNP haplotypes. The genetic diversity ...
Adoption of maize production technologies in Northern Tanzania
(SADC; CIMMYT; SACCAR, 1998)
The impact of maize research and extension in Tanzania's Northern Zone during the past 20 years was evaluated through a formal survey in 1995. Data were grouped into two major agroecological zones: the intermediate and the ...
An assessment of factors affecting adoption of maize production technologies in Iganga District, Uganda
(NARO; CIMMYT, 1997)
Data from formal farmer surveys in Iganga District, Uganda, as well as secondary data, were analysed to describe maize farmers' circumstances and practices, identify socioeconomic and technical factors affecting the adoption ...
Potential impact of investments in drought tolerant maize in Africa
The study evaluates the potential impacts of the Drought Tolerant Maize for Africa (DTMA) project run by CIMMYT and the International Institute for Tropical Agriculture (IITA) in 13 countries of eastern, southern and West ...
Determinants of fertilizer and manure use for maize production in Kiambu District, Kenya
(CIMMYT; KARI, 2001)
Farms in Kiambu District are very small owing to high population pressure and need to be intensively farmed to provide enough food for consumption and sale. Since soil nitrogen levels are low, the use of inorganic fertilizers ...
