Agricultural technology adoption, seed access constraints and commercialization in Ethiopia
(Academic Journals, 2011)
This article examines the driving forces behind farmers? decisions to adopt agricultural technologies and the causal impact of adoption on farmers? integration into output market using data obtained from a random cross-section ...
Outlook of future climate in northwestern Ethiopia
Climate change is described as the most universal and irreversible environmental problem facing the planet Earth. While climate change is already manifesting in Ethiopia through changes in temperature and rainfall, its ...
Factors influencing adoption of stress-tolerant maize hybrid (WH 502) in western Kenya
(Academic Journals, 2007)
Non-adoption of suitable maize varieties was identified as the second most important constraint responsible for low maize yields in western Kenya. In order to increase adoption of suitable varieties it is important to know ...
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 ...

Genetic diversity of African maize inbred lines revealed by SSR markers
(BioMed Central, 2007)
Knowledge of genetic diversity (GD) and relationships among maize inbred lines is indispensable in a breeding program. Our objectives were to (1) investigate the level of genetic diversity among maize inbred lines and (2) ...
First detection of Pseudomonas fuscovaginae on maize and sorghum in Burundi
(American Phytopathological Society (APS), 1989)
Pseudomonas fuscovaginae was isolated from brown rot lesions on leaf sheaths and husks of maize at the silking stage and on flag leaf sheaths of sorghum at the booting stage in smallholders’ fields between 1,450 and 2,100 ...
Races of Puccinia graminis f. sp. tritici with combined virulence to Sr13 and Sr9e in a field stem rust screening nursery in Ethiopia
(American Phytopathological Society (APS), 2012)
North American durum lines, selected for resistance to TTKSK (Ug99) and related races of Puccinia graminis f. sp. tritici in Kenya, became susceptible in Debre Zeit, Ethiopia, suggesting the presence of stem rust races ...
First report of Puccinia graminis f. sp. tritici races with virulence to wheat stem rust resistance genes Sr31 and Sr24 in Eritrea
(American Phytopathological Society (APS), 2011)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, has historically been a major limiting factor in wheat production. Identification of isolate Ug99 in Uganda in 1999 highlighted the vulnerability of a large ...
The spread of stem rust caused by Puccinia graminis f. sp. tritici, with Virulence on Sr31 in wheat in Eastern Africa
(American Phytopathological Society (APS), 2006)
Stem rust resistance in wheat cultivars with Sr31 has been effective and durable worldwide for more than 30 years. Isolates of Puccinia graminis f. sp. tritici with virulence to Sr31 were detected in Uganda in 1999 (1). ...
