A Classification of tourism offerings based on intrinsic attributes
(International Journal of Business and Social Research, 2015)The purpose of this study is to explore intrinsic attributes that can be used in the classification of tourism offerings for an academic understanding of their immutable natures. Mixed approach of visitor attractions ... -
An importance-performance analysis of food service attributes in gastro-tourism development in Western Tourist Circuit, Kenya
(Sage, 2013)Tourism development has principally focused on the tangible tourism products thereby overlooking the intangible element such as service. This study aimed to evaluate food service attributes in gastro-tourism development ... -
Effects of housing on growth performance of common house cricket (Acheta domesticus) and field cricket (Gryllus bimaculatus)
(Journal of Entomology and Zoology Studies, 2017-08-16)Cricket rearing is emerging as an important component of animal food. However, suitable housing for medium and large - scale production still presents a major challenge. This study sought to investigate the effect of housing ... -
Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Global Science Books, 2009-01-21)Solanum villosum is an important leafy vegetable in Kenya whose production faces low yields. Two potentially high leaf-yielding genotypes of S. villosum, T-5 and an octoploid have been developed. Field experiments were ... -
Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Afr. J. Hort. Sci., 2009)Seven tomato (Lycopersicon sp.) accessions were evaluated for their resistance to the tomato red spider mite, Tetranychus evansi Baker and Pritchard, in the laboratory. Data recorded was: (i) trichome density and (ii) ... -
High fluoride water in Bondo-Rarieda area of Siaya County, Kenya: a hydro-geological implication on public health in the Lake Victoria basin
(BMC Public Health, 2014)Background: Only a few studies to evaluate groundwater fluoride in Eastern Africa have been undertaken outsidethe volcanic belt of the Great Eastern Africa Rift Valley. The extent and impact of water fluoride outside ... -
Polyploidy Breeding of African Nightshade ( Solanum section Solanum )
(Global Science Books, 2007)The perception of African nightshades ( Solanum section Solanum ) as “healthy” foods, supported by documentation of their high nutri- tional and medicinal benefits, has led to a sudden and ... -
Exploiting the Genetic Diversity of Vegetable African Nightshades
(Global Science Books, 2013)frican nightshades ( Solanum section Solanum ) are an important source of daily nutrients and income for small-scale farmers in sub- Saharan Africa and are a delicacy for urban inhabitants. The section ... -
Effects of day-length and temperature on floral structure and fertility restoration in a season-dependent male-sterile Solanum villosum Mill. mutant
(Springer Verlag, 2007)Solanum villosum is an important African leafy vegetable whose yield is limited mainly by competition from early and excess fruit-set. Induced male-sterility is a potential tool to reduce this competition and enhance yields. ... -
Response of tomato genotypes to induced salt stress
(African Crop Science Society, 2003-12-31)Thirteen tomato (Lycopersicon esculentum L.) genotypes were subjected to salt treatment under hydroponics and their responses monitored in a set of two experiments with the objective of advancing them as potential salt ... -
