The Effect Of Invasive Species Lantana Camara On Soil Chemistry At Ol- Donyo Sabuk National Park, Kenya

ABSTRACTInvasive species are a major ecological and management concern in natural ecosystems and pose a threat to many of Kenya’s protected areas. Invasive plant species compete and hybridize with native species often to the disadvantage of the native species. Invasion can lead to the phasing out of native species and loss of ecosystem services such as water filtration, soil stabilization, and pest control. They may also result in reduction of wildlife forage or death of animals when they f...

To increase their usefulness, some reservoirs have been stocked with fish, even though no studies have been carried out to establish their suitability and potential for fish culture. This study therefore aimed at assessing the water quality, fish food availability and fisheries productivity of three ...

Effects Of Water Stress On Antioxidant Activity And Phenolic Contents Of African Nightshades And Their Distribution In Kisii And Siaya Counties Of Kenya

ABSTRACTDrought is a major abiotic factor limiting crop productivity in many regions of the world. It causes reduction in plant growth, dry matter accumulation and decline in plant water status of the plants and in certain cases interferes with biochemical processes within cultivated crops. The aim of the study was to map out the distribution of different African Nightshade species in Siaya and Kisii Counties of Kenya and to determine water stress effect on total antioxidant capacity and tota...

Study Of Bioavailability Of Trace Elements In Selected Indigenous Foods And Their Potential Use On Management Of Hiv And Aids

ABSTRACTHIV infection increases nutritional demands and vulnerability to malnutrition. Malnutrition worsens the effects of HIV infection by weakening further the body’s immune system, resulting in earlier and faster progression to the end stage of AIDS. Food supplementation especially with essential elements improves nutritional and clinical status of PLWHA and may delay early use of ARVs. Although high levels of essential elements have been recorded in some indigenous foods, translating ph...

Ultraviolet Radiation And Selenium Nutrition On Yield, Biochemical Composition And Sensory Quality Of Selected Tea Varieties In Kericho County, Kenya

ABSTRACT Ultraviolet (UVB) radiation (280–315 nm) and interaction with Selenium (Se) have potential promoting plant tolerance to UVB stress in plants and modify metabolites that influence taste and functional properties of tea. The objectives of this study were to assess sensitivity of two tea varieties to ambient solar UVB radiation and Selenium nutrition on 1) yield components,2) secondary metabolites, antioxidant activity, theanine and mineral composition of tea and 3) non-aerated ...

Contribution Of Ngusishi Water Resource User Association Towards Farm Forestry Adoption In Ewaso Ng’iro North Catchment Area, Kenya

ABSTRACTTraditional perspective approach has always considered environmental resources such as water as free goods without physical boundaries and the complexity of water uses and users makes it difficult to manage water resources in an efficient and equitable way. In addition, the current low tree planting trends and over harvesting imbalances are suspect and feared to threaten the continuity of the very tree-crop growing practice that has supported farming households over the years. The Ngu...

Distribution, Utilization and Management of Prunus africana (Hook. f) in Gichugu Division, Kirinyaga District, Central Kenya

ABSTRACT Prunus africana (Hook. f) Kalkman happens to be among the very important tree species. Its bark is used to treat prostate gland hypertrophy (PGH) and benign prostatic hyperplasia (BPH). The increased demand for its medicinal value, together with other uses, has led to the over exploitation of this species in its natural habitat. Its cultivation by small-scale farmers appears to be the only long-term solution for meeting future products needs and its conservation. There is howev...

Linkages Between Integrated Soil Fertility Management Technologies And Marketing Of Smallholder Produce In Meru South And Mbeere Districts, Kenya

ABSTRACT Land degradation and declining soil fertility are increasingly being viewed as critical problems affecting agricultural productivity and human welfare in tropical Africa. It is then imperative that improving soil fertility is key entry point for achieving food security, reducing poverty and preserving the environment for smallholder farms in Africa. However, due to high costs of inorganic fertilizers, tackling soil fertility issues thus requires a holistic approach that integra...

Pig Management Practices And Their Contribution To Ocurrence Of Porcine Cysticercosis In Thika Municipality And Its Environs, Kenya

ABSTRACTThe pork tapeworm (Taenia solium) is an important parasite that causes disease in humans and pigs where humans host the adult worm in the small intestines and the larval stages are found in the muscles, brain and other tissues in humans and pigs (cysticercosis). Neurocysticercosisis (where the larva of Taenia solium is in the brain) is a major cause of epilepsy in humans. Humans can get the infection by consumption of infected pig meat while consumption of food and water contaminated ...

Effects Of Nitrogen Fertilizer On Yields And Quality Of Selected Rice Varieties At Mwea Irrigation Scheme, Kirinyaga County, Kenya
