Brucellosis is an infectious zoonotic disease caused by bacteria of the genera Brucella. Brucellosis is mainly a disease of livestock infecting cattle, sheep, goats, pigs, dogs and marine mammals. In humans, the disease is acquired directl…
Laboratory studies were conducted in the Biotechnology Laboratory, Egerton University, Kenya to determine fumigant activity (space and grain fumigation) of essential oils of the Mexican cypress (C. lusitanica) and Sydney blue gum (E. Salig…
Most studies are focused on fertiliser either organic or inorganic to improve soil fertility, health and crop yields in most of the farming systems worldwide. Although organic and inorganic soil fertility improvements impact indirectly on …
Nutrient mining resulting from crop uptake and erosion; and soil acidity which makes plant nutrients less available through different means such as phosphorus fixation and impairment of biological mediated processes in the soil. A study wa…
Although accurate estimates of losses and waste in the food system are unavailable, the best evidence to date coming from Food and Agricultural Organisation (FAO) indicates that approximately 1.3 billion tonnes per year (one-third of the f…
Continuous cropping without nutrient restitution under smallholder farms in Rwanda has led to serious nutrient depletion and reduced maize (Zea mays) yields. This is further exacerbated by low soil organic matter and soil erosion. The smal…
Soybeans are a major source of protein; they contribute to combating malnutrition especially among children. They play very important roles in NRM because they contribute to biological nitrogen fixation through the inoculation with rhizobi…
A survey was carried out in Nakuru and Narok Counties at hard dough stage and at harvest. A semi structured questionnaire was used to collect information on wheat production practices. Fusarium head blight incidence and severity in each fa…
The “pocket” hand-held Normalized Difference Vegetative Index (NDVI) sensor for inseason highland quality protein maize nitrogen rate determination for side-dressing was conducted in 2013cropping season on seven farmers’ field around Bako-…
Biomass accumulation and nitrogen fixation of soybean (Glycine max) and grain yields of maize (Zea mays) and soybean intercropped at different planting densities was assessed in two villages of Butere and Mumias district of western Kenya d…
Banana Xanthomonas Wilt (BXW) ( Xanthomonas campestris pv. musacearum -Xcm) disease is considered the most important threat to banana production in the Great Lakes Region of Africa. Insect vectors are one of the key ways through which the …
The red locust (Nomadacris septemfasciata Serville) is one of the most devastating migratory pests of crops in several African countries south of the equator. It originates from small areas characterised by a mosaic of tall and short grass…
Soil nitrite (NO2-) and nitrate (NO3-) along the soil profile can be used as indicators of nitrogen loss by leaching. Preliminary studies have shown that excess usage of fertiliser is common amongst farmers who were aiming to increase crop…
Mango (Mangifera indica) is a tropical fruit adapted to a wide range of agro-ecological conditions. In Kenya, mango fruits are produced across various agro-ecological zones (AEZs); from sub-humid to semi-arid. The diverse production condit…
Sweet sorghums (Sorghum bicolor L. Moench) are sorghum varieties that accumulate high levels of sucrose in the parenchyma juicy stems. Sweet sorghum (SS) is a multifunctional crop. It that can be cultivated for simultaneous production of g…
Conventional cultivation in Western Kenya and Eastern Uganda over the years has resulted into decline in soil quality and food crop production. Studying soil biodiversity under Conservation Agriculture production systems (CAPS) will help u…
Fusarium head blight is a disease of small grain cereals that reduces yield and causes mycotoxin contamination. The role of agronomic practices on the occurrence of wheat agronomic practices was studied. In the experiment, a survey to dete…
Passionfruit viral pathogens limit passionfruit production and are non-persistently transmitted by aphid vectors, the diseases can reduce orchard life span to only a year resulting to 100% yield loss. 50-100% loss due to biotic stresses ha…
African indigenous vegetables form an integral part of the Kenyan diets, among the most commonly consumed being the African nightshade. These vegetables contain important phenolics that have medicinal values and good health attributes. The…
An 8 x 8 diallel cross mating design with the parents and F1s excluding the reciprocals was used to estimate gene action and combining ability analysis for yield and some yield components in sesame (Sesamum indicum). These genotypes were e…
Rust caused by the fungi Uromyces appendiculatus is considered as one of the most variable pathogens documented world-wide. In Uganda, rust has been identified as an emerging common bean disease and this has contributed to its being given …
Methanol extracts of Lion’s ear, Leonotis nepetifolia L. (LN) and African basil, Ocimum gratissimum L. (OG), were evaluated for their toxic and ovicidal effects against the female adult two-spotted spider mite, Tetranychus urticae Koch. La…
A field survey was carried out in Narok County, Kenya, at hard dough growth stage (GS 65- 69) during the 2013 cropping season and sampling done in 51 wheat farms in different agroecological zones. Samples of soil and crop residues were col…
The potential of crude plant extracts as antimicrobial agents has been demonstrated both in animal and plant health. Extracts with potential for control of plant pathogens such as Colletotrichum lindemuthianum (causal agent for bean anthro…
This research established aphid vectors and alternate hosts of Passiflora chlorotic mottle virus in Uganda. Aphids and host plants were collected from farmers’ fields in major passion fruit growing districts in Uganda. Transmission tests w…
