Traditional strategies used by pastoralists to cope with la nina induced drought in Kajiado, Kenya
(University of NairobiSchool of Biological Sciences,, 2008)Pastoralists traditionally relied on herd mobility to cope with drought. In the pastoral areas of Kajiado, Kenya this strategy is now threatened by increased individual land ownership as compared to communal access. ... -
Resilience of soils and vegetation subjected to different grazing intensities in a semi‐arid rangeland of Kenya
(University of NairobiWangare Mathai institute for peace and envinment, 1997)The resilience of rangeland soils and vegetation to different levels of grazing is still poorly understood. A study was conducted to determine the recovery of a rangeland grazed at different intensities and allowed a ... -
Increased plant density and shade affects flowering and fruiting of pumpkin (C. pepo)
(Department of Plant Science and Crop Protetion, 1997)Increase in plant density often results in reduction in reproductive potential of individual plants in cucurbits. The reduction may be due to reduced female flower production or a reduction or a delay in fruit set or to ... -
Evaluation of Verticillium chlamydosporium and Arthrobotrys oligospora for biological control of Meloidogyne incognita in celery and tomato
(2007)The ability of nematode trapping fungi and egg-parasitising fungi to colonize and persist in the rhizosphere of crop plants is thought to be an important factor influencing the success of biological control of root infecting ... -
Validation of tuber blight (Phytophthora infestans) prediction model
(Department of Plant Science and Crop Protetion, 2011)Potato tuber blight caused by Phytophthora infestans accounts for significant losses of tubers in storage. Despite research on infection and management of tuber blight, there is paucity of information on the prediction of ... -
Effect of endophytic Fusarium oxysporum on growth of tissue-cultured banana plants
(2009)Endophytes which are mutualistic symbiots living asymptomatically within plant tissues have been reported to have beneficial effects on plant growth. In bananas a wide diversity of endophytic fungi have been isolated from ... -
Recent developments in managing tuber blight of potato (Solanum tuberosum) caused by Phytophthora infestans
(Department of Plant Science and Crop Protetion, 2009)Tuber blight, caused by Phytophthora infestans, occurs wherever potato (Solanum tuberosum) is cultivated and accounts for significant losses under field and storage conditions. After decades of research in late blight, ... -
Monitoring of Aphid Fauna in Passionfruit Orchards in Kenya
(University of NairobiPlant Science and Crop Protection department, 2013)Passionfruit woodiness disease viral pathogens limit passionfruit production and are non-persistently transmitted by aphid vectors. The study was conducted to identify aphid species and assess the population dynamics ... -
Relationship between late blight [Phytophthora infestans] of potato on tuber and foliage, as affected by the disease severity on foliage, cultivar resistance, and atmospheric and soil variables
(Department of Plant Science and Crop Protetion, 2007)Potato tuber blight, caused by Phytophthora infestans, is an important component of the late blight pathosystem. Although the dynamics of tuber blight on potato (Solanum tuberosum) cultivars have been evaluated, the effects ... -
Mechanical transmission ofTrypanosoma evansiandT. congolensebyStomoxys nigerandS. taeniatusin a laboratory mouse model
(WileyDepartment of Physics, University of Nairobi, 2002)Mechanical transmission of Trypanosoma evansi (South American origin) and T. congolense of Kilifi DNA type (Kenyan origin) was studied in laboratory mice using the African stable flies Stomoxys niger niger and S. taeniatus. ... -
Farmers' cultural practices and management of potato late blight in Kenya Highlands: implications for development of integrated disease management
(Department of Plant Science and Crop Protetion, 2004)A survey of 277 farmers in three major potato-growing areas in Kenya was conducted in 2000 and 2001 with the aims of assessing farmers' current perception and knowledge of late blight and practices for its management and ... -
Yield and water use efficiencies of maize and cowpea as affected by tillage and cropping systems in semi-arid Eastern Kenya
(University of Nairobi,Department of Land Resource Management and Agricultural Technology, 2012)Soil water conservation through tillage is widely accepted as one of the ways of improving crop yields in rainfed agriculture. Field experiments were conducted between 2007 and 2009 to evaluate the effects of conservation ... -
Response of free-living nematodes to treatments targeting plant parasitic nematodes in carnation
(Department of Plant Science and Crop Protetion, 2008)This study was carried out with the aim of evaluating the effect of ecologically sound approaches for nematode management on non-target organisms, free-living nematodes. The materials tested were sugarcane bagasse, molasses, ... -
Modelling the potential impact of climate change on sorghum and cowpea production in semi-arid areas of Kenya using the agricultural production systems simulator (APSIM
(Department of Land Resource Management and Agricultural Technology, 2010)Managing crop production risks associated with inter-annual climate variability and climate change has received insignificant attention in the semi-arid areas of Kenya. Against this backdrop, the potential impact of ... -
The value of radiographs obtained during forced traction under general anaesthesia in predicting flexibility in idiopathic scoliosis with Cobb angles exceeding 60 degree
(2008)Our aim in this prospective radiological study was to determine whether the flexibility rate calculated from radiographs obtained during forced traction under general anaesthesia, was better than that of fulcrum-bending ... -
Two distinct regions of FC gamma RI initiate separate signalling pathways involved in endocytosis and phagocytosis
(1995)Cross-linking of the high affinity receptor for IgG, Fc gamma RI, can result in both endocytosis of immune complexes and phagocytosis of opsonized particles in myeloid cells, although the cytoplasmic domain of the receptor ... -
Open peritoneal drainage for treatment of contaminated peritoneal cavity and septic peritonitis in dogs and cats: 24 Cases (1980-1986).
(University of NairobiFaculty of Veterinary Science, 1987-07)The medical records of 22 dogs and 2 cats in which generalized peritonitis had been treated by open peritoneal drainage were reviewed. The age of the affected animals ranged from 5 months to 14 years. The causes of peritonitis ... -
Soil moisture dynamics under different tillage practices in cassava–sorghum based cropping systems in Eastern Uganda
(University of NairobiDepartment of Land Resource Management and Agricultural Technology, 2013)Soil moisture storage in the root zone determines availability of water in crop production, but there is limited attention on water resource management in cassava–sorghum production systems. Soil moisture content was higher ... -
