Biofortified sorghum in Africa: using problem formulation to inform risk assessment
(Nat. Biotechnol., 2010)Most of the genetically modified (GM) crops approved to date (eg, corn, cotton and soybean improved for insect resistance or herbicide tolerance) do not have compatible wild relatives near their intended area of cultivation, ... -
Face attack and patients’ response strategies in a Kenyan hospital†
(Journal of social linguistics, 2010)Social power can be exercised by face attack where power differentials are sufficiently great and significant retaliation or sanctions are unlikely. Such exercise of social power is common in military contexts. It is not ... -
Roots spatial distribution and growth in bambara groundnuts (Vigna subterranea) and NERICA rice (Oryza sativa) intercrop system
(Asian Research Publishing Network (ARPN)., 2010)Intercropping offers advantages if well planned including improved soil fertility and yields. Bambara groundnuts have been shown to yield in low fertility soils and have been described as a complete food. NERICA rice has ... -
Chlorophyll fluorescence, protein and chlorophyll content of three nerica rainfed rice varieties under varying irrigation regimes
(2010)Water deficit affects growth and development of rainfed rice leading to a considerable yield reduction or crop failure. Although the rice crop is susceptible to water deficit, there is a marked genotypic variation in protein ... -
An Assessment of the Viability and Potential of Bamboo Micro Enterprises in Environmental Conservation and Poverty Alleviation in Nairobi City, Kenya
(Maseno University, 2010)Nairobi, Kenya‟s capital city has undergone rapid urbanization which has been associated with a number of development challenges. Key among these challenges is deterioration in urban environment and urban poverty. Bamboo ... -
Effects of water deficit on physiology and morphology of three varieties of NERICA rainfed rice (Oryza sativa L.)
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Agrobiodiversity endangered by sugarcane farming in Mumias and Nzoia Sugarbelts of Western Kenya
(2010)Commercial sugarcane farming has been practised in western Kenya for nearly forty years. This monocultural land use is associated with loss of natural vegetation and cropland, thus undermining food security status of a ... -
Ethnobotanical study of medicinal plants used by Sabaots of Mt. Elgon Kenya.
(africanethnomedicines, 2010)Though the majority of people in Kenya and at Kopsiro Division in species to manage human ailments, the indigenous knowledge largely remains undocumented. Therefore, an ethnobotanical study was conducted on medicinal plant ... -
Performance of some quinoa (Chenopodium quinoa Willd.) genotypes in Kenya
(Taylor & Francis, 2010-01-01)Quinoa (Chenopdium quinoa Willd.) has been cultivated for thousands of years in South America for its nutritious grain and leaves. Demand for the crop has risen in the recent past. In order to satisfy the demand, there is ... -
Effects of water deficit on days to maturity and yield of three NERICA rainfed rice varieties
(2010-05)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Responses of ecosystem carbon dioxide fluxes to soil moisture fluctuations in a moist Kenyan savanna
(Cambridge University Press, 2010-11-01)act: Measurements were conducted within a fence-exclosure between February 2008 and July 2009 to investigate the influence of soil moisture on ecosystem CO2 fluxes in a Themeda irifl/idra-dominated grassland of a humid ... -
Evaluation of ecologies and severity of Striga weed on rice in sub-Saharan Africa
(Science Hub, LLC, 2011)Striga spp. is renowned for causing great losses in cereal production in sub-Saharan Africa. Crop competitiveness with parasitic weeds such as Striga is an important criterion for selection in an initiative to produce ... -
Pedological perspective of gully erosion sites within Kendu escarpment-Sondu Miriu Region, West Kenya
(2011)Gully erosion is a common feature in western Kenya, rendering large expanses of otherwise arable land uncultivable and uninhabitable. Gully erosion in the area was classified into two types: the Awach-type and the Sondu-type. ... -
The role of wetlands in the changing ecophysiology and distribution of plant species: a comprehensive review
(2011)Wetlands are important ecosystems globally. Changes in plant species physiology, species composition, species distribution and phenology have occurred with changes and modifications of wetland ecosystems. This paper ... -
