Assessment of Four Commercial Watermelon Cultivars and one Local Landrace for Their Response to Naturally Occurring Diseases Pests and Non-Pathogenic Disorders in Sub-Humid Tropical Conditions
(Asian Research Publishing Network (ARPN), 2008-09)Four commercial watermelon cultivars available in Kenya and one local landrace were evaluated for their susceptibility/resistance to naturally occurring diseases, pests and non-pathogenic disorders. The accessions included ... -
Biosafety education relevant to genetically engineered crops for academic and non-academic stakeholders in East Africa
(2009-01-15)Development and deployment of genetically engineered crops requires effective environmental and food safety assessment capacity. In-country expertise is needed to make locally appropriate decisions. In April 2007, biosafety ... -
Characterization of algae oil (oilgae) and its potential as biofuel in Kenya
(2012-05)A survey of microalgae biodiversity in three Kenyan Rift valley lakes identified high oil yielding species abundantly distributed naturally. The species were cultured in BBM and BG-11 media to obtain pure clones and lipids ... -
Comparing the yield components of three most popular commercial watermelon cultivars in Kenya with one newly introduced cultivar and one landrace
(Academic Journals, 2009-06)High yield is a major goal for watermelon (Citrullus lanatus) breeders. The objective of this study was to compare the yield components of some watermelon accessions available in Kenya and to identify high yielding ... -
Do afroalpine plants differ from other alpine plants by their leaf functional traits?
(UoEm, 2023-06-16)Afroalpine plants develop under specific climate with great daily fluctuations and weak seasonal dynamics of temperature. Do leaf functional traits of the plants in Mt. Kenya differ from those of temperate plants in ... -
Effect of Different Watering Regimes on Agromorphology of Selected Coffee Genotypes
(SCIENCEDOMAIN international, 2014-01-27)Aims: The aim of this study was to determine the effect of different watering regimes on selected coffee genotypes and to evaluate drought tolerance among selected coffee genotypes. The study also aimed at determining ... -
Field Screening of Selected Coffea arabica L. Genotypes Against Coffee Leaf Rust
(2012-06)Coffee Leaf Rust (CLR) is a fungal disease caused by Hemileia vastatrix Berk et Br. and is one of the major diseases of coffee. It causes premature leaf fall, yield loss and even death of the tree in severe cases. Coffee ... -
Genetic diversity among commercial coffee varieties, advanced selections and museum collections in Kenya using molecular markers
(Academic Journals, 2012-02)Molecular markers have effectively been applied to study genetic diversity and as markers of particular traits. This study assessed the diversity of twenty four (24) coffee genotypes using 10 Random Amplified Polymorphic ... -
Geomorphic and Climatic Drivers Are Key Determinants of Structural Variability of Mangrove Forests along the Kenyan Coast
(MDPI, 2022-06)Mangrove forests occur across a diversity of coastal landforms that influence their structural development and productivity. Preliminary studies in Kenya indicate that mangroves growing in the region north and south of ... -
Hepatitis B infection is highly prevalent among patients presenting with jaundice in Kenya
(2016-02)Background:Viral hepatitis is a major concern worldwide, with hepatitis A (HAV) and E (HEV) viruses showing sporadic outbreaks while hepatitis B (HBV) and C (HCV) viruses are associated with chronic hepatitis, cirrhosis ... -
Hepatitis B virus subgenotype A1, occurrence of subgenotype D4, and S gene mutations among voluntary blood donors in Kenya
(Springer, 2013-05-24)Kenya is one of the high endemic zones for hepatitis B virus (HBV) infection. The consensuses on prevalence of the HBV genotypes and the existence of their variants have not been fully established in Kenya. Hence, there ... -
Human Immunodeficiency Virus -1 and Hepatitis B Virus Co-Infections among Injecting Drug Users in Malindi, Kenya
(IISTE, 2015-12)Currently no published data addressing the burden of Human Immunodeficiency Virus (HIV) and Hepatitis B Virus (HBV) co-infection among injecting drug users (IDUs) in Kenya exists. These two viruses share similar routes of ... -
Incidence of Brucella infection in various livestock species raised under the pastoral production system in Isiolo County, Kenya
(BMC, 2021-10)Background: We implemented a longitudinal study to determine the incidence of Brucella infection in cattle, camels, sheep and goats that were being raised in a pastoral area in Isiolo County, Kenya. An initial cross-sectional ... -
Methods for early evaluation for resistance to bacterial blight of coffee
(Academic Journals, 2013)Bacterial Blight of Coffee (BBC) caused by Pseudomonas syringae pv garcae has become of major concern in Kenya due to its increasing incidence and severity. For decades, the disease was confined within and to the west of ... -
Mitochondrial DNA variation of Bemisia tabaci (gennadius) (hemiptera: aleyrodidae) infesting cassava in Kenya
(2011)Bemisia tabaci is a widely distributed crop pest affecting the yield of a broad range of agricultural, fiber, vegetableand ornamental crops. It is an extremely polyphagous pest that causes direct damage and can act as a ... -
Molecular detection of uncultured cyanobacteria and aminotransferase domains for cyanotoxin production in sediments of different Kenyan lakes
(Blackwell Publishing Ltd, 2009-04-15)PCR-based denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA gene fragments was used to identify the cyanobacterial phylotypes in sediments and plankton of saline–alkaline and freshwater lakes of Kenya. ... -
