Biopesticide-based IPM systems to reduce synthetic pesticide residues in vegetables for niche market access by small holder growers
(University of Nairobi, 2016)
In the last few decades, farmers have relied on synthetic pesticides to managed crop pests and diseases. This is because synthetic pesticides are easily available, have quick knock down effect, have varied modes of action ...
Controlling soil erosion in smallholder potato farming systems using legume intercrops
(University of Nairobi, 2019)
Competition for nitrogen (N) and phosphorous (P) under potato-based intercropping systems decreases the level of nutrients available for potato and subsequently influences nitrogen and phosphorous use efficiency. A field ...
Viability and Dormancy of Rice Seeds after Storage and Pre-Treatment with Dry Heat and Chemical Agents
(University of Nairobi, 2017)
Inappropriate seed packaging and seed dormancy affects seed quality and consequently leads to reduced crop stand, low seedling vigour and reduced yields. The objective of the study was to determine the effect of seed ...
Seroepidemiological Survey of Rift Valley Fever Virus in Ruminants in Garissa, Kenya
(University of Nairobi, 2017)
Introduction: Rift Valley fever (RVF) is a vector-borne zoonotic disease caused by phlebovirus in the family Bunyaviridae. In Kenya, major outbreaks occurred in 1997–1998 and 2006–2007 leading to human deaths, huge economic ...
Clinically relevant antimicrobial resistance at the wildlife-livestock-human interface in Nairobi: an epidemiological study.
(University of Nairobi, 2019)
BACKGROUND:
Antimicrobial resistance is one of the great challenges facing global health security in the modern era. Wildlife, particularly those that use urban environments, are an important but understudied component ...
Producers' valuation of geographical indications-related attributes of agri-food products from semi-arid lands in Kenya.
(University of Nairobi, 2019)
Arid and semi-arid lands comprise 84% of Kenya's land, characterised by low and erratic rainfall, and increasing human and animal population. The study sought to determine producers' willingness to pay for protection of ...
Deterministic processes structure bacterial genetic communities across an urban landscape.
(Deterministic processes structure bacterial genetic communities across an urban landscape., 2019)
Land-use change is predicted to act as a driver of zoonotic disease emergence through human exposure to novel microbial diversity, but evidence for the effects of environmental change on microbial communities in vertebrates ...
Regeneration-Competent And -Incompetent Murids Differ In Neutrophil Quantity And Function
(University of Nairobi, 2019)
Regeneration is rare in mammals, but spiny mice (Acomys spp.) naturally regenerate skin and ear holes. Inflammation is thought to inhibit regeneration during wound healing, but aspects of inflammation contribute to both ...
Integration of Seed Dressing, Bio-pesticides and Intercropping to Reduce Pesticide Use in Snap Bean Production
(University of Nairobi, 2018)
Insect pests remain a major constratint in the production of snap beans and farmers mainly rely on synthetic
chemical pesticides to manage the insect pests and diseases. However, the introduction of maximum residue levels ...
Seasonal Dynamics and Alternate Hosts of Thrips Transmitted Iris Yellow Spot Virus in Kenya
(University of Nairobi, 2018)
Thrips-transmitted Iris yellow spot virus (IYSV) (Family Tospoviridae, Genus Orthotospovirus) is a major
constraint to onion (Allium cepa L.) production in Kenya. Determining seasonal patterns of the vector and
alternate ...
