Impacts of Covid-19 Pandemic and Adaptive Strategies to Build Resilience in the Kenyan Aquaculture Sector
(ScienceOpen, 2022)This study examines the impacts of the Covid-19 pandemic and adaptive strategies to build resilience among stakeholders and actors in the aquaculture value chain in Kenya. Prior to the pandemic, Kenya's aquaculture sector ... -
Socio-economic consequences of imported frozen tilapia in the Kenyan aquaculture value chain: Strategies for optimizing local unexploited potential
(ScienceOpen, 2022)The capture fisheries production sector, which is the main source of consumed fish in Kenya has been declining over the years, causing a huge deficit in fish supply in the local market. Even though aquaculture has been ... -
Fish and fish products consumption behaviours and attitudes of farmers in western Kenya.
(ResearchGate, 2022)Fish and fish products contain high-quality protein of animal origin with essential bioavailable micronutrients such as iron, zinc, vitamins and omega-3 fatty acids. Although fish contribute to food and nutrition security, ... -

Genetic and non-genetic factors influencing KLH binding natural antibodies and specific antibody response to Newcastle disease in Kenyan chicken populations
(Wiley Online Library, 2023)This study aimed at investigating the influence of genetic and non-genetic factors on immune traits to inform on possibilities of genetic improvement of disease resistance traits in local chicken of Kenya. Immune traits ... -
Farm diversification benefits and technology choice: A case of the coffee-banana farming system in Central Uganda
(African Journal of Agricultural Research, 2023)Diversification has been argued to be the future of small farms and more so in developing countries given its benefits to mitigating against risk, increase economic and social benefits. This study was built on an earlier ... -
Sorghum is an important staple food crop in Kenya, but its yield is low due to many constraints which include diseases, drought, soil fertility, and pests, notably parasitic weed Striga hermonthica. Twenty elite sorghum genotypes and one resistant check were evaluated in three replications in a complete randomized design in Agar Gel (AG) experiment and randomized complete block design on selected Striga hotspot farms at Kadel and Nyahera in western Kenya. Significant differences (p<0.001) were realized both in the fields (plant height, dry shoot biomass yield, grain yield, field Striga count, and Striga damage ratings) and in the AG experiment with respect to maximum germination distance and numbers of induced germinated Striga seeds. Among the sorghum genotypes evaluated under field conditions, T53B, N57, N68, C26, IESV 92036-SH, T30B, and Uyoma 47 White genotypes had stable yields under Striga infestation in the two sites, whereas Nyadundo 1, Nyadundo 2, and Uyoma 8 were susceptible. In the AG experiment, E117B, T30B, Uyoma 8, Uyoma 42 STR, and T53B induced high numbers of germinated Striga seeds with maximum germination distances (MGD). In contrast, Uyoma 47 Brown, IESV 92038/2-SH, and IESV 92036-SH sorghum genotypes secreted low amounts of SLS suggesting resistance. This study has identified and selected four Striga tolerant (T53B, N68, N57, and T 30B) and resistant (C 26, Uyoma 47 Brown, IESV 92038/2-SH, and IESV 92036- SH) sorghum genotypes which can be utilized in further research programs or adopted to improve sorghum productivity in the highly Striga infested regions of western Kenya.

Genetic association of agronomic traits with partial resistance to gray leaf spot in elite maize germplasm.
(John Wiley & Sons, 2022)Studies on gray leaf spot (GLS) of maize have reported inconsistencies in the relationship between partial disease resistance and agronomic traits. Understanding this variation could facilitate the use of agronomic traits ... -
Effects of Organic Substrates on Development and Survival of Blattela germanica for Food and Feed in Kenya
(Scientific Research Publishing, 2022)Entomophagy has gained popularity as a novel approach to addressing food and nutrition insecurity, particularly in sub-tropical and tropical countries. Cockroaches, for example, have the potential to alleviate nutritional ... -
