(Journal of Entomology and Nematology, 2014)This study assesses the pathogenicity of Metarhizium anisopliae isolate ICIPE 51 against different nymphal instars and adults of Rhopalosiphum padi and Metopolophium dirhodum and investigates effects of fungal infection ... -
Disparity between Leaf and Root Symptoms and Crop Losses Associated with Cassava Brown Streak Disease in Four Countries in Eastern Africa
(Journal of phytopathology, 2015)Cassava brown streak disease is endemic to the coastal regions of East Africa, and from around 2004, the disease resurged and became epidemic in the Great Lakes Region, where it continues to spread. In both these areas, ... -
Antibacterial activity of Moringa oleifera and Moringa stenopetala methanol and n-hexane seed extracts on bacteria implicated in water borne diseases
(African Journal of Microbiology Research, 2010-11)The anti-bacterial activity of methanol and n-hexane extracts of Moringa oleifera and Moringa stenopetala seeds was conducted on 3 bacterial species (Salmonella typhii, Vibrio cholerae and Escherichia coli) which normally ... -
Seed Potato Growth, Harvest Index and Net Economic Benefit Improvement through Irrigation Water, Nitrogen and Phosphorus Management
(Columbia International Publishing American Journal of Agricultural Science and Technology, 2016)A study was conducted in a Rainshelter (RTrial) at Egerton University to determine the correlation between irrigation water, nitrogen (N) and phosphorus (P) application on seed potato growth, harvest index (HI) and net ... -
Micro-Dosing of Lime, Phosphorus and Nitrogen Fertilizers Effect on Maize Performance on an Acid Soil in Kenya
(Sustainable Agriculture Research, 2015-03-17)High cost of inorganic fertilizers and lime has precluded their use by smallholder farmers to remedy the problem of soil acidity and infertility in Kenya. To address the problem, we tested a precision technique referred ... -
Recent advances towards understanding and managing Kenyan acid soils for improved crop production
(African Journal of Agricultural Reseach, 2014-06-18) -
Effects of combining organic materials with inorganic phosphorus sources on maize yield and financial benefits in western Kenya
(Cambridge University Press, 2009-10-09) -
Effect of organic and inorganic phosphorus sources on maize yields in an acid soil in western Kenya
(Research Gate, 2009-06-20)Maize production in western Kenya is commonly limited by P deficiencies and aluminum phytotoxicity. Due to high costs of imported fertilizers and lime, focus is now shifting to solutions that utilize local resources. We ... -
Influence of Cropping System and Residue Management on Selected Soil Chemical Properties
(Advances in Research., 2018-02-09)Declining soil fertility in sub-Saharan Africa caused by continuous cropping without nutrient inputs has resulted in declining crop yield. The study was aimed to determine the effects of crop rotation and crop residue ... -
Molecular markers associated with aluminium tolerance in Sorghum bicolor
(Hereditas, 2018)Background: Sorghum (Sorghum bicolor, L. Moench) production in many agro-ecologies is constrained by a variety of stresses, including high levels of aluminium (Al) commonly found in acid soils. Therefore, for such soils, ... -
Efficacy of nutrition counselling on energy and micronutrient intake of pregnant women in Migori County, Kenya
(Research Journal of Food Science and Nutrition, 2017)A large number of pregnant women in many parts of the world enter pregnancy at sub-optimal weight. More than 60% of Kenyan population suffers from food insecurity. The result is malnutrition which primarily affects pregnant ... -
Effect of Light and Temperature through Poly Film Covers on Anthocyanin Content in Rose Cut Flowers
(International Journal of Plant & Soil Science, 2017)Quality is the most important attribute in rose cut flowers for both export and domestic market. Quality in cut flowers may be defined by many attributes however, among the most important is colour. A group of pigments ... -
