(International Journal of Genetics and Molecular Biology, 202-07-31)The first report of Maize lethal necrosis (MLN) disease in Africa was in Bomet, Kenya, nine years ago. It has since spread in East and Central African (ECA) countries, causing massive yield losses. Currently, 90% of the ... -
Occurrence and distribution of cassava begomoviruses in Kenya
(Annals of Applied Biology, 2005-03-16)SummaryA survey for cassava mosaic disease (CMD) was conducted in Kenya, to investigate the factors contributing to the generally increased incidence and severity of CMD in the cassava growing regions and to study the ... -
Improving Smallholder Marketing of potatoes and groundnuts in Eastern Uganda.
(FARM-D, 2005-05-23)Farmers’ collective marketing has successfully been implemented in Western Kenya, but the potential has remained unexploited in Uganda. The project seeks to enhance marketing efficiency by improving access to credit for ... -
Groundwater overdraft vulnerability and environmental impact assessment in Arusha
(Environmental Geology, 2006-07-11)A simple approach is proposed for identifying areas vulnerable to groundwater overdraft. The methodology utilizes GIS techniques to analyze and evaluate controlling factors in areas with little data. The proposed methodology ... -
Adsorption of Caffeine and Ciprofloxacin onto Pyrolitically Derived Water Hyacinth Biochar: Isothermal, Kinetic and Thermodynamic Studies
(2006-09)In this work, the adsorptive features of water hyacinth (Eichhornia crassipes) derived biochar for sequestration of ciprofloxacin and caffeine from aqueous solution is reported. The isothermal behaviour, adsorption kinetics, ... -
Environmental impact assessment of risk associated with groundwater overdraft remediation in cone of depression, Jining, China
(Environmental Geology, 2007-03-21)In this paper, a simple scenario and probabilistic approach is used to assess the potential groundwater risk due to proposed overdraft remedial actions in cone of depression, Jining City, China. Focusing on the concentrations ... -
Environmental impact assessment using FORM and groundwater system reliability concept
(Environmental Geology, 2007-09-20)In this paper, fist-order reliability method (FORM) is used to evaluate the impacts of uncertainties posed by traditional deterministic models on the environment in Jining, China. Because of groundwater contamination in ... -
In vitro Regeneration by Indirect Organogenesis of Selected Kenyan Maize Genotypes using Shoot Apices
(Biotechnology, 2008-09)The study reports a reliable and reproducible regeneration system of two open pollinated varieties-OPV`s (Katumani KAT and dry land cultivar DLC1), a hybrid (DH01) and an inbred line (TL08) using shoot apices as explants ... -
Effects of Plant Age and Rock Phosphate on Quality and Nutrient Release of Legume Residue
(Pedosphere, 2009-02)An incubation experiment was carried out on plateau and slope fields to investigate the effect of plant age and rock phosphate (RP) on the organic resource (OR) quality and available N and P release of the legume residues, ... -
