Levels Of Selected Antinutrients, Vitamins And Minerals In African Indigenous Vegetable Recipes In Vihiga County Of Western Kenya

ABSTRACT African Indigenous Vegetables (AIVs) have been recommended as the most affordable source of minerals and vitamins for African families. They can be used to alleviate micronutrient deficiencies but have been underutilized due to lack of nutrition information, leading to consumption of the lesser nutritious exotic vegetables. Vihiga County is endowed with these AIVs but cases of micronutrient deficiencies remain a challenge. The potential of these AIVs as sources of micronutrients is ...

Nodulation and nitrogen fixation potential of sesbania spp. Rhizobia on sesbania sesban (l.) Merr. And rose coco (phaseolus vulgaris l.)

ABSTRACT Global crop and energy production are fast dwindling inversely to population growth. Common bean (Phaseolus vulgaris L.) yield has reduced worldwide due to soil infertility which can be reversed through application of chemical fertilizers. The chemical fertilizers used to ameliorate nitrogen, phoshorus and potassium are expensive and cause both deleterious physico‒chemical modification of soil and water mass eutrophication. The common bean has ability to fix atmospheric nitrogen s...

Effects Of Climate Variability On Maize Yield In Matungulu West, Machakos County Kenya

ABSTRACT Climate variability is now a reality and its effects continue to affect agriculture especially crop yields. Maize is said to be one of the crops adversely affected by climate variability. It is projected that unless bold steps are taken to reduce the effects of climate variability on crop yields, then the magnitude of its effect shall be enormous. It is based on this uncertainty that this paper was premised to interrogate the effects of climate variability (temperature and precipita...

Evaluation Of Bacillus Thuringiensis Var Israelensis And Bacillus Sphaericus Briquets As Anopheles Mosquito Larvicides In Vihiga County, Western Kenya

ABSTRACT Malaria is a key hindrance to the improvement of health in tropical and subtropical countries of the world with more than two billion people exposed to it. One of the approaches of controlling vectors of malaria is by targeting aquatic stages at source. This would lead to significant reduction in the adult vectors as well as malaria transmission. Entomopathogenic bacteria Bacillus thuriengiensis var israelensis (Bti) and Bacillus sphaericus (Bs) in the form of dispersable granular f...

Phenotypic And Genotypic Characterisation Of Diarrhoeagenic Escherichia Coli Isolated From Children In Mukuru Informal Settlement, Nairobi County, Kenya

ABSTRACT Diarrhoeal diseases in Kenya are among the five main causes of mortality in children younger than five years. Bacterial diarrhoea has been reported to account for up to 30 % of all cases of infantile diarrhoea. Among children of age five years and below, diarrhoeagenic E. coli (DEC) such as enterotoxigenic E. coli (ETEC), enteropathogenic E. coli (EPEC), enteroaggregative E. coli (EAEC) are the most important enteric pathogens and are responsible for 30 to 40 % of all the diarrhoeal...

Prevalence And Association Of Conventional And Novel Risk Factors For Coronary Heart Disease In Langata Constituency, Nairobi, Kenya

ABSTRACT  There has been considerable progress in the understanding of conventional risk factors for cardiovascular disease such as cigarette smoking, hypertension, hyperlipideamia and diabetes. However they do not fully account for cardiovascular disease-associated complications. As a result, novel risk factors such as C-reactive protein (CRP) and homocysteine have come under investigation. The aim of this study was to determine the prevalence and interrelation of conventional and novel ris...

Evaluation Of Quantity And Quality Of Biodiesel Produced From Jatropha Curcas In Different Parts Of Kenya

ABSTRACT Biodiesel as an alternative fuel for diesel engines is becoming increasingly important due to diminishing petroleum reserves and the environmental consequences of exhaust gases from petroleum-fuelled engines. The availability and sustainability of sufficient supplies of less expensive feedstock will be a crucial determinant delivering a competitive biodiesel to the commercial filling stations. Fortunately, inedible vegetable oils, mostly produced by seed-bearing trees and shrubs can...
