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 ... -
Long-term effects of tillage, sub-soiling, and profile strata on properties of a Vitric Andosol in the Kenyan highlands
(2008-09)Tillage alters the structure and composition of soil aggregates affecting infiltration rate (IR) and hydraulic conductivity (K). This study investigated the long-term effects of conventional, minimum, and no-tillage with ... -
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 ... -

(2014-02)Background: Anopheles gambiae is the main carrier for parasites that cause malaria and filariasis as well as viruses that cause yellow fever, dengue fever, dengue haemorrhagic fever, chikungunya and encephalitis. Culex ... -
Cultural Characterization of Fungi Isolated From Oil Contaminated Soils
(IISTE, 2015)Application of Fungi for effective removal of hydrocarbon contamination from soil is being considered as the better option when it comes to biodegradation. Other method like physical and chemical bioremediation leads to ... -
454 Pyrosequencing‑based assessment of bacterial diversity and community structure in termite guts, mounds and surrounding soils
(2015-09)Termites constitute part of diverse and economically important termite fauna in Africa, but information on gut microbiota and their associated soil microbiome is still inadequate. In this study, we assessed and compared ... -
Genetic diversity of determinate French beans grown in Kenya based on morpho-agronomic and simple sequence repeat variation
