Survey of sweet potato viruses in Western Kenya and detection of cucumber mosaic virus.
(2010)
Sweet potato is an important food crop worldwide, but several pests and diseases limit its
production. In eastern Africa, virus-induced diseases rank second to weevils in causing yield reduction. Symptomatic sweet potato ...
Reproduction of root knot nematode (Meloidogyne icognita) on Bt cotton expressing Cry1Ac and Cry2Ab2 protein.
(2013)
Objective: The sedentary endoparasite Meloidogyne incognita is an important plant parasitic nematode that infects cotton causing significant yield losses. The objective of this study was to evaluate reproduction of M. ...
Evaluation of an Antigen-Antibody “Combination” Enzyme Linked Immunosorbent Assay For Diagnosis Of Hepatitis C Virus Infections
(2014-10)
BACKGROUND: Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction ...
Chemical Properties Associated with Guts, Soil and Nest Materials of Odontotermes and Macrotermes Species from Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2010)
Changes in carbon and nitrogen cycles in tropical soils affect soil functioning and ecosystem activity. Termites play important roles in carbon and nitrogen cycles, thus determination of levels of such compounds is essential. ...
Physicochemical Characteristics of undrainable Water Dams Utilized for Fish rearing In The Semi-Arid Naromoru Area, Central Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2012)
Naromoru is a semiarid area in Central Kenya, occurring on the leeward side of Mt. Kenya. Its water sources include a few permanent rivers such as Nairobi River, intermittent streams and a large number of undrainable water ...
The Contribution of Occult Precipitation to Nutrient Deposition on the West Coast of South Africa
(2015-05)
The Strandveld mediterranean-ecosystem of the west coast of South Africa supports floristically diverse vegetation growing on mostly nutrient-poor aeolian sands and extending from the Atlantic Ocean tens of kilometers ...
Early performance of five newly developed lines of Arabica Coffee under varying environment and spacing in Kenya
(2010)
Knowledge of the effects of environment and genotype by environment (GxE) interaction is important to breeders in making decisions regarding the release of new cultivars. Five Coffea arabica lines coded CR8, CR22, CR23, ...
Isolation, characterization and identification of Diazinon degrading bacteria from the soil and gut of macrotermes
(2013)
Diazinon degrading bacteria were isolated from the soil and gut of fungus cultivating termites Macrotermes michaelseni using MM7 media supplemented with pesticide as the sole source of carbon and energy. The isolates were ...
Variation and Association of Cup Quality Attributes and Resistance to Coffee Berry Disease in Coffea Arabica L. Composite Cultivar, Ruiru 11
(2013-12)
Majority of reported work on coffee breeding primarily concerns agronomic improvement that directly impinges on coffee quality. However, it is crucial that coffee breeding programmes for disease resistance also include ...
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 ...
