Effect of land preparation and weeding on maize (Zea mays) grain yields in the coastal region of Kenya
(Taylor & Francis Group, 1993-01-01)A field study was conducted at the Regional Research Centre, Mtwapa and at the Msabaha subcentre in Kilifi District of Coast Province, Kenya between 1986 and 1989. The objective of this study was to investigate the effects ... -
Long-term effects of fertility and hand-weeding on Striga in maize.
(1994)Tanzania has recently embarked into a period of liberalisation which is undoubtedly having an impact on the agricultural sector. The effects of liberalisation are feeding through to the animal feeds sector, which is ... -
The prevalence of anxiety and depression symptoms and syndromes in Kenyan children and adolescents
(Taylor & Francis Group, 2008-08-01)Background: Community studies on children and adolescents in Western settings suggest prevalence rates of anxiety and depressive symptoms that require intervention. Aim: To establish equivalent prevalence rates in a Kenyan ... -
Effect of intercropping maize and beans on Striga incidence and grain yield. Integrated Approaches to Higher Maize Productivity in the New Millennium.
(2002)^ AIntercrops can smother weeds in cereal crops and improve the overall productivity. Although intercropping with beans has long been practised in the region, a practical bean population and arrangement is required in the ... -
Transposons and tolerance; teh identification of genes for Striga tolerance in maize. Integrated Approaches to Higher Maize Productivity in the New Millennium.
(2002)^ AStriga is one of the most severe constraints to cereal production in areas of the semi-arid tropics of Africa where subsistence agriculture is predominant. The development of Striga tolerant or resistant germplasm has ... -
Development and diffusion of integrated Striga control practices for small-scale farmers in western Kenya
(Centro Internacional de Agricultura Tropical (CIAT), Participatory Research and Gender Analysis Program (PRGA), 2002)The parasitic weed Striga hermonthica has become one of the most significant constraints to cereal production in western Kenya. In 1995 a collaborative project among CIMMYT, the University of Hohenheim (UH) and the Kenyan ... -

Integrated pest and soil management to combat striga, stem borers and declining soil fertility in the Lake Victoria Basin
(Final Technical Report, 2005-04-20)Demonstrations with best-bet technologies for the control of Striga weed and stemborers and enhancement of soil fertility were initiated in the long rainy season (March to July) of 2003 in Kenya and Uganda and during the ... -
Next priorities for intervention in Kenya: Results from a cohort study of drug use, HIV and HCV patterns in five urban areas
(University Of Nairobi, 2006)In Kenya, alcohol, cigarettes, Khat (miraa) and cannabis sativa, have remained the most popular abused substance and have been linked to increasing rates of HIV/HCV . This study’s objective was to identify the types, ... -
INTEGRATING CROP MANAGEMENT PRACTICES FOR STRIGA CONTROL
(2007)Striga spp. are pernicious pests of food crops in Africa for which an integrated control program is needed. An effective integrated program must have components that are adaptable to the biophysical and socio-economic ... -
Traumatic Experiences of Kenyan Secondry School Students
(University of Nairobi, 2007)There is no information on the socio-demographic variations and determinants of Trauma and Post-Traumatic Stress Disorder (PTSD) in Kenyan adolescents. Objectives: To describe the traumatic experiences of Kenyan high school ... -
Plant growth-promoting rhizobacteria do not pose any deleterious effect on cowpea and detectable amounts of ethylene are produced
(Kluwer Academic Publishers, 2007-06-01)The use of trap crops such as cowpea could reduce the effects of the root parasitic weed, Striga hermonthica and its subsequent constraints on the growth of cereals. Certain bacteria could augment the trap crop stimulatory ... -
A study of drug use in five urban centres in kenya
(University Of Nairobi, 2008)Few studies have addressed the reasons for substance use in Kenya, with most focusing on prevalence rates in school-based and general population samples. None have been carried out among people already using drugs. This ... -
Economic efficiency and supply response of women as farm managers: Comparative evidence from Western Keny
(Pergamon, 2008-07-01)This paper assessed the relative economic efficiency and output supply and input demand responses of women farmers in western Kenya. The results showed that women are as technically and allocatively efficient as men. ... -
Soil nitrogen amendment effects on maize productivity under two different soil conditions in western Kenya.
(Kenya Forestry Research Institute, 2009)The effect of integrated use of urea and calliandra or maize stover on yield and N uptake of maize was assessed in a field experiment carried out on two soil types in western Kenya. Urea and calliandra or maize stover were ... -
Effect of farmyard manure and inorganic fertilizers on maize production on Alfisols and Ultisols in Kakamega, western Kenya.
(JO Achieng, G Ouma, G Odhiambo, F Muyekho, 2010)Soil acidity is one property associated with decline of most crop productivity. Alfisols and Ultisols are some of the acidic soils predominant in western Kenya. An experiment was conducted in both soils to find out the ...
