Response of Chia (Salvia Hispanica) to Water Stress, Plant Density and Nitrogen Fertilizer in Two Agro-ecological Zones of Kenya
(University of Nairobi, 2023)Chia (Salvia hispanica) is gaining popularity worldwide due to its nutritional and health benefits. In Kenya, production of chia seed is relatively new, and the crop has gained attention hence prompting the possibility of ... -
Response of diminazene resistant and diminazene susceptible trypanosoma congolense to treatment with diminazene when occurring as a mixed infection in goats
(Department of Clinical studies, University of Nairobi, 1992)The research described in this thesis was carried out to investigate the phenotypic basis of resistance to diminazene (Berenil R) in Trypanosoma congolense. Earlier work has shown that, in both goats and mice, the ... -
