Investigations on decomposition of foliage of woody species using a perfusion method
(1992)The time for half of the total oxidizable carbon to be converted into C02 and other gaseous products (t1/2) was studied for five tree species used in agroforestry. The study was conducted in a perfusion system with ... -
The status of pesticide usage in East Africa
(Research Gate, 1994)The assumption proposed by Gallo in 1984 that the cause of AIDS is infection with HIV was founded on the correlation between detection of antibodies to this virus and the onset of AIDS. This view became generally accepted, ... -
The Impact of Human Activities on Epibenthic Bivalve Communities
(1997-10)A total of 17 bivalve species belonging to 13 families were collected and identified in Malindi and Mombasa Marine National Parks; and Kanamai from Oct.'97 to Mar.'98. Bivalve fauna showed low densities (2/m2), and low ... -
Impact of agro-industrial activities on the water quality of River Nyando, Lake Victoria Basin, Kenya
(2002)The impact of agro-industrial activities on the water quality within River Nyando, Lake Victoria Basin was studied at different hierarchical levels between August 1997 and June 1999. Triplicate water samples were collected ... -
Interference of large crabgrass (Digitaria sanguinalis) with snap beans
(Cambridge University Press on behalf of the Weed Science Society of America, 2003)Field experiments were conducted to determine the effect of large crabgrass densities of 0.5 to 8 plants m-1 of row and emergence time on snap bean yield. Large crabgrass was planted either along with snap beans (early) ... -
Shifts in the food of Nile tilapia, Oreochromis niloticus (L.) in Lake Victoria, Kenya
(African Journal of Ecology, 2004)Studies of the food of introduced Nile tilapia, Oreochromis niloticus (L.) with respect to size, habitat and season were conducted between November 1998 and October 2000 in Kenyan waters of Lake Victoria. Stomach contents ... -
Interaction of Insects and Weeds in a Snap Bean Agroecosystem
(2004)Abstract.Integrated weed management strategies maintain sub-threshold levels of weeds. The remaining weeds may impact the feeding and habitation patterns of both potato leafhoppers and bean leaf beetles in a snap bean ... -
Aquaculture Strategy For Restoration of Threatened Lake Victoria Fishes
(The East African Community, 2006)The endemic Oreochromis variabilis and L. victorianus are among Lake Victoria’s most threatened fish species whose population sizes are on the decline. This study, carried out between August 2000 and April 2001, aimed ... -
Effect of Harvesting on Temporal Papyrus (cyperus papyrus L.) Population among Swamps of Winam Gulf in Lake Victoria Basin, Kenya
(2008-07-29)Experiments were set to determine the effect of monthly and seasonal harvesting on temporal papyrus population density. Mean initial culm count was 21.6±2.26/m2. Initial culm counts varied across sites, but spatial ... -
Response of Males of Maruca vitrata Fabricius(Lepidoptera: Pyralidae) to Synthetic Lures in Mauritius
(University of Mauritius research journal, 2009)Maruca vitrata Fabricius (Lepidoptera: Pyralidae) is a key pest of bean in Mauritius. Their larvae feed within flowers and pods and are thus well protected from insecticidal sprays. To achieve effective control, ... -
Interactive effects of packaging and storage temperatures on the shelf-life of okra
(ARPN Journal of Agricultural and Biological Science, 2009-05)A study aimed at evaluating the potential benefits of pre-packaging and storage temperature in extending the shelf life of okra was conducted at Egerton University Horticulture Field and Biotechnology Laboratory. Okra ... -
Effect of organic and inorganic phosphorus sources on maize yields in an acid soil in western Kenya
(Research Gate, 2009-06-20)Maize production in western Kenya is commonly limited by P deficiencies and aluminum phytotoxicity. Due to high costs of imported fertilizers and lime, focus is now shifting to solutions that utilize local resources. We ... -
Effects of combining organic materials with inorganic phosphorus sources on maize yield and financial benefits in western Kenya
(Cambridge University Press, 2009-10-09) -
Effects of cowpea leaf harvesting initiation time on yields and profitability of a dual purpose sole cowpea and cowpea maize intercrop
(2010)Harvesting of cowpea leaves for use as leaf vegetable has gained prominence in many parts of Africa and Asia. Little is known on effects of leaf harvesting on leaf and grain yields and profitability of cowpea-based ... -
Antibacterial activity of Moringa oleifera and Moringa stenopetala methanol and n-hexane seed extracts on bacteria implicated in water borne diseases
(African Journal of Microbiology Research, 2010-11)The anti-bacterial activity of methanol and n-hexane extracts of Moringa oleifera and Moringa stenopetala seeds was conducted on 3 bacterial species (Salmonella typhii, Vibrio cholerae and Escherichia coli) which normally ... -
Harvesting surface rainwater – purification using Moringa oleifera seed extracts and aluminum sulfate
(Journal of Agricultural Extension and Rural Development, 2011)Ground water harvesting is a method of collecting surface runoff from a catchment’s area and storing it in surface reservoirs. The water harvested is usually contaminated and turbid. Methods used to purify water include ... -
