Relationship between mites infestation levels in Kenyan tea to overhead volatile organic compounds and their variations with seasons, regions and selected agronomic practices
(Maseno University, 2016)
Tea (Camellia sinensis) is a major cash crop in Kenya that suffers economic losses due to Brevipalpus phoenicis and Oligonychus coffeae infestations during droughts. Pesticides use on tea is prohibited and pests control ...
Evaluation of chlorpyrifos ethyl elisa kit and assessment of use and spatial distribution and temporal trend of selected organophosphate and carbamate pesticides residues in water, sediment and fish from lake Naivasha
(Maseno University, 2015)
Heavy seasonal use of specific organophosphate and carbamate in the catchment area of Lake Naivasha is a potential cause of pollution of sediment, water and fish in the lake. However, there is lack of data on the potential ...
Comparison of Variations in Soil-Foliar Nutrients Levels and Productivity of Three Ratoon-Sugarcane Cultivars Due to Nitrogen-Potash Rates and Harvesting Age in Western Kenya
(2016)
Sugarcane productivity in Kenya has declined despite increased acreage and new cultivars possibly due to use of old-cultivar agronomic inputs. The N-K2O optimal rates for new cultivars are unknown. Kenya Sugar Industry ...
Effect of NPK blended fertilizer application on soil chemical properties, growth, Chlorophyll content and nutrient uptake on Finger millet (Eleusine coracana l. gaertn.) grown in acidic soils.
(Maseno University, 2017)
Finger millet (Eleusine coracana L) is one of the most important cereal crops in Kenya. It is an important staple food rich in minerals and vitamins required for good health. Finger millet has the ability to grow in stressful ...
Phytochemical investigations of lonchocarpus eriocalyx (harms), alysicarpus ovalifolius (schumach) and erythrina abyssinica (dc) for antiplasmodial, larvicidal, mosquitocidal and antimicrobial activities
(Maseno University, 2016)
Management of parasitic disease continues to be a burden and a major public health problem the world over today. Malaria is most lethal of the parasitic vector-borne diseases due to drug and vector resistance to the available ...
Optimization of Graphene oxide with methyl-β-Cyclodextrin and carbon Nanotubes with Polypyrrole for removal of lead (ii) and copper (ii) ions from water
(Maseno University, 2018)
ABSTRACT
Heavy metals pose risks to the humans and the environment. Lead (II) and copper (II) are of particular concern because they can cause irreversible damage to vital body organs. Their sources include leaded paints, ...

Effects of Anthropogenic Activities on Selected Water Quality Parameters in Spring Water and Sediments along Amala and Nyangores Tributaries in the Mara River Basin, Kenya
(Maseno University, 2014)
Replacing natural forests with commercial crops and/or other small scale farming activities including human settlement have several environmental impacts. The land LISt' practices have the potential of contaminating aquatic ...
Kinetic Studies of Malathion Dissipation Degradation in Lake Victoria Water in the Presence of Zeolite
(Maseno University, 2011)
Malathion is an organophosphorus pesticide widely employed in controlling pests in agriculture,
household, stored grains, greenhouse, forestry and public health. Malathion usually adsorbs on
soilsand through surface ...
