Morphological characterization of soil bacteria in Ngere tea catchment area of Murang'a County, Kenya
(2015-02)Bacteria are a very diverse group of organisms in soil, and major taxonomic groups are represented in most soils. The extent of the diversity of microorganisms in soil is seen to be critical to the maintenance of soil ... -
Is leaf pubescence of Cape Proteaceae a xeromorphic or radiation-protective trait?
(CSIRO Publishing, 2012-03)Although pubescence has traditionally been considered to be related to the water economy of plants, the results are ambivalent and vary between different species. We tested two contrasting hypotheses for the functional ... -
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 ... -
Distribution of indigenous strains of atoxigenic and toxigenic Aspergillus flavus and Aspergillus parasiticus in maize and peanuts agro‑ecological zones of Kenya
(Springer (BioMed Central Ltd), 2015-09)Background Grains of important food and export crops in Africa are susceptible to contamination by toxin-producing moulds. Aflatoxins are mycotoxins associated with liver damage and cancer in humans and animals. These ... -
Collembola Richness and Diversity along A Land-Use Intensity Gradient in Taita, Kenya
(2009)Soil Collembola communities were sampled along a gradient of land use intensification in Taita-Taveta, Wundanyi division, Coast Province during the wet season (October-November 2007) and dry season (February- March ... -
Collembola Density and Diversity along a Gradient of Land- Use Types in Embu District, Eastern Kenya
(2009)Populations of soil-dwelling Collembola were monitored on a land use gradient ranging from Natural forests to intensively cultivated land during the wet season October-November, 2007 and dry season February-March, 2008. ... -
Potential side effects of biocontrol and plant-growth promoting Bacillus amyloliquefaciens bacteria on earthworms
(Elsevier, 2015-08)Many bacteria strains are now successfully used for plant-growth promotion (PGPR) and as biocontrol agents (BCA) against plant diseases. Mechanisms behind their action involve production of enzymes and antibiotics, which ... -
Effect of Integrated Soil Fertility Management Interventions on the Abundance and Diversity of Soil Collembola in Embu and Taita Districts, Kenya
(2011)The study aimed at identifying soil fertility management practices that promote the Collembola population, diversity and survival in the soil. Soil samples were randomly collected from on farm plots amended with: 1-Mavuno ... -
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 ... -
Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya’s Central Highlands
(Springer, 2015-03)Drier parts of Kenya’s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding ... -
Applicability of conservation agriculture for climate change adaptation in Rwanda’s situation
(Academic Journals, 2015-09)Improving food security and environmental conservation should be the main targets of innovative farming systems. Conservation agriculture (CA), based on minimum tillage, crop residue retention and crop rotations has been ... -
Using Apsim-Model as A Decision-Support-Tool for Long-Term Integrated-Nitrogen-Management and Maize productivity under Semi-Arid Conditions in Kenya
(Cambridge University Press, 2015-04)There is continued decline in per capita agricultural productivity in the drier parts of Kenya’s central highlands. The declines have been linked to low and declining soil fertility, soil water, high atmospheric heat, ... -
Effects of selected soil and water conservation techniques on runoff, sediment yield and maize productivity under sub-humid and semi-arid conditions in Kenya
(Elsevier, 2014-05)tillage practices on runoff amounts, sediment yield and maize yields under semi-arid and sub-humid environments. Field trials were set in Kigogo primary school in Meru South Sub-County, Tharaka Nithi County, representing ... -
Effects of selected soil and water conservation technologies onnutrient losses and maize yields in the central highlands of Kenya
(Elsevier, 2014-02)tMitigating nutrient loss is a prerequisite of sustainable agriculture in the tropics. We evaluated threesoil and water conservation technologies (mulching, minimum tillage and tied ridging) for two croppingseasons (long ... -
Rainfall Variability, Drought Characterization, and Efficacy of Rainfall Data Reconstruction: Case of Eastern Kenya
(Hindawi Publishing Corporation, 2015)This study examined the extent of seasonal rainfall variability, drought occurrence, and the efficacy of interpolation techniques in eastern Kenya. Analyses of rainfall variability utilized rainfall anomaly index, coefficients ... -
Length of growing season, rainfall temporal distribution, onset and cessation dates in the Kenyan highlands
(Elsevier, 2013-12)Dependence on uncertain rainfall and exposure to unmitigated climate risk are major obstacles in efforts to sustainably intensify agricultural production and enhance rural livelihoods. There is generally enough seasonal ... -
Influence of Organisational Staff Capacity on the Implementation of Electronic Project Monitoring Information System in Public Tertiary Institutions in Kenya
(2015-10)This article highlights on the urgent need for staff training on new technologies, provision of adequate ICT infrastructure and staff attitudinal change trainings for effective implementation of new electronic based systems. ... -
Influence of Organizational Strategy on Implementation of Electronic Project Monitoring Information System in Public Tertiary Institutions in Kenya
(2015-09)The principal objective of the study reported in this article was to empirically assess on the influence of organisational strategy on the implementation of Electronic Project Monitoring Information System (e-ProMIS) in ... -
