Histidine rich protein ii and lactate dehydrogenase levels in saliva and blood in acute malaria cases in Kisumu, western Kenya
(Maseno university, 2024)Globally, malaria is the leading cause of death and economic burden. Diagnosis currently relies on microscopy and blood-based rapid diagnostic tests (RDTs). However, both methods are invasive, which increases the risk of ... -
Effect of maize- soya bean intercropping patterns on growth, yield and photosynthetic active radiation of soya beans in Kaimosi-Vihiga county, Kenya
(Maseno university, 2024)Cereal-legume combination is the common form of intercropping by most small-scale farmers in Sub-Saharan Africa (SSA). This is because of small pieces of land owned by farmers small causing overexploitation of resources ... -
Impact of altitude variation and grassland composiition on stemborer and fall armyworm population in maize farms and surrounding grasses in western Kenya during 2019-2020 rain season
(Maseno university, 2024)Grassland ecosystems adjacent to maize farms are often habitats for pests that pose significant risks to maize crops. Among these pests, lepidopteran stemborers and fall armyworm are the most detrimental, negatively impacting ... -
