Different land use types in the semi-arid rangelands of Kenya influence soil properties
(Department of Plant Science and Crop Protection, 2011)Rangelands in semi-arid Kenya have recently witnessed extensive land use changes. These changes can mainly be attributed to increased livestock populations and the response of the increased human population to both local ... -
The challenges of rehabilitating denuded patches of a semi-arid environment in Kenya
(Department of Plant Science and Crop Protection, 2010)Land degradation is a major problem in the semi-arid environments of Sub-Saharan Africa. Fighting land degradation is essential to ensure the sustainable and long-term productivity of the habited semiarid lands. In Kenya, ... -
Dry matter yields and hydrological properties of three perennial grasses of a semi-arid environment in east Africa
(Department of Plant Science and Crop Protection, 2010)Enteropogon macrostachyus (Bush rye), Cenchrus ciliaris L. (African foxtail grass) and Eragrostis superba Peyr (Maasai love grass) are important perennial rangeland grasses in Kenya. They provide an important source of ... -
Land-Use Change and Livestock Production Challenges in an Integrated System: The Masai-Mara Ecosystem, Kenya
(Department of Plant Science and Crop Protection, 2009)Participatory rural appraisal techniques and a survey of 100 households were used to evaluate livestock production, and pastoral development of the Maasai in Mara. It was observed that patterns of land-use have principally ... -
Low Cost Technologies for Enhancing N and P Availability and Maize (Zea mays L.) Performance on Acid Soils
(Department of Land Resource Management and Agricultural Technology, 2008)Soil degradation especially soil acidity and low fertility are the major constraints hampering maize production in Molo district, Kenya. The challenge therefore is to develop sustainable soil management strategies for ... -
Organic based nutrient management strategies: Effect on soil nutrient availability and maize (Zea mays L.) performance in Njoro, Kenya
(Department of Land Resource Management and Agricultural Technology, 2009)A field experiment based on the concept of organic nutrient management (ONM) was conducted in Njoro, Kenya to test the effect of improved legume fallows; crotalaria (CR), lablab (LB), garden pea (GP) and natural fallow ... -
Mineral Nitrogen and Microbial Biomass Dynamics under Different Acid Soil Management Practices for Maize Production
(Department of Land Resource Management and Agricultural Technology, 2010)Field and laboratory incubation studies were conducted to determine the effect of different acid soil management practices; liming (L), combined N and P fertilizers (NP), and goat manure (M) application, for maize production ... -

Effects of legume cover crop and sub-soiling on soil properties and maize (zea mays l) growth in semi arid area of Machakos District, Kenya
(Department of Plant Science and Crop Protection, 2010)Low crop yields in the semi arid areas of Kenya have been attributed to, among other factors, low soilfertility, low farm inputs, labour constraints and inappropriate tillage practices that lead to pulverized soils. The ... -
Effects of Temperature on Germination of Seeds of Three Pigeonpea (Cajanus cajant Genotypes
(Department of Crop Science, 1993-10)Two sets of incubator experiments to determine the effects of temperature on germination of three pigeonpea genotype seeds were carried out in the Crop Science Laboratory of the Faculty of Agriculture, University of Nairobi. ... -
Effect of Deflowering and Defoliation During Reproductive Phase on Flower and Pod Abscission and Yield of Pigeon Peas
(Department of Crop Science, 1993-12)Two indeterminate genotypes of pigeon pea, 423/60 and ICPL 7403 and a determinate genotype NPP 670, were subjected to deflowering and defoliation treatments under glass-house and field conditions. Four levels of deflowering, ... -

(Department of Plant Science and Crop Protection, 2010)Principal component analysis was used to analyze data collected from a dynamic study of thirty mixed dairy-crop farmers. The study was undertaken for II months over two rainy seasons to analyze the major production factors ... -
Analysis of" -Kenyan isolates' of Fusarium "safani f. sp. phaseoli from common bean using colony characteristics, pathogenicity and microsatellite DNA
(Department of Plant Science and Crop Protection, 2008)Fusarium solani (Mart) f.sp. phaseoli (Burk) Synd. and Hans., is a plant pathogeniC fungus that causes root rot in garden bean (Phaseo/us vulgaris L.). To evaluate methods used in classifying strains of this pathogen, 52 ... -
DNA Microsatellite Analysis of Kenyan Isolates of Rhizoctonia solani from Common Bean (Phaseolus vulgaris L.)
(Department of Plant Science and Crop Protection, 2007)Seven hundred and fifty bean plant samples with root rot symptoms were collected from farmers' fields during two surreys carried out in Embu district, Kenya. Various fungal pathogens were isolated in the laboratory from ... -
High Efficacy of Combined Albendazole and Ivermectin Treatment Against Gastrointestinal Nematodes in Vervet Monkeys and Baboons
(2010)Conventional treatment that eliminates other gastrointestinal nematodes has failed to show adequate efficacy against Trichuris trichura in non-human primates (NHPs). We investigated the efficacy of albendazole and ivermectin ... -
