Increasing accuracy in estimation of economic values for resistance to gastrointestinal helminths in meat sheep
(Department of Animal Production, University of Nairobi, 2010-03)The impact of utilising different indices and numbers of index traits in estimation of economic values (EVs) for resistance to gastrointestinal (GI) helminths were investigated. Seven indices based on yearling weight (YW), ... -
Does ethylene play a role in thidiazuron-regulated somatic embryogenesis of geranium (Pelargonium × hortorum bailey) hypocotyl cultures?
(Department of Plant Science and Crop Protection, 1997)The accumulation of ethylene in headspace of hypocotyl cultures of geranium (Pelargonium × hortorum Bailey) and its possible role in thidiazuron-mediated somatic embryogenesis was investigated. The action of ethylene as ... -
Optimisation of breeding schemes for litter size, lambing interval, body weight and parasite resistance for sheep in Kenya
(Department of Animal Production, University of Nairobi, 2011)The current study optimised breeding schemes for litter size (LS), lambing interval (LI), body weight (BW) and gastrointestinal parasite resistance for sheep in Kenya. Selection for the breeding goal traits was performed ... -
Evaluation of alternative selection objectives and schemes for optimisation of village goat improvement programs. Livestock Research for Rural Development; 24 (1)
(Department of Animal Production, University of Nairobi, 2012)This study evaluated alternative breeding objectives and schemes for crossbred goats in a village/ community breeding program. A single-tier breeding structure was assumed in the optimisation of this breeding program. ... -
Acetylsalicylic acid enhances and synchronizes thidiazuron-induced somatic embryogenesis in geranium (Pelargonium x hortorum Bailey) tissue cultures
(Department of Plant Science and Crop Protection, 1996-03)Thidiazuron (TDZ) effectively induced somatic embryogenesis in cultured hypocotyl explants of geranium (Pelargonium x hortorum Bailey) during only a 3-day period of induction. The presence of acetylsalicylic acid (ASA) ... -
Role of purine metabolism in thidiazuron-induced somatic embryogenesis of geranium (Pelargonium×hortorum) hypocotyl cultures
(Department of Plant Science and Crop Protection, 1996)Somatic embryogenesis in geranium (Pelargonium×hortorum Bailey cv. Scarlet Orbit Improved) was achieved by culturing hypocotyl sections on Murashige and Skoog (1962) (MS) medium containing 10 μM thidiazuron (TDZ) (induction ... -
Callus induction and plant regeneration from mature zygotic embryos of a tetraploid Alstroemeria (A. pelegrina × A. psittacina)
(Department of Plant Science and Crop Protection, 1994-12)A simple procedure was developed to induce callus growth and whole plant regeneration for a tetraploid cultivar of Alstroemeria. The callus, induced from mature zygotic embryos cultured on a medium supplemented with 20 μM ... -
Land Use, Ecology, and Socio-economic Changes in a Pastoral Production System
(University of Nairobi,Department of land resource management and agricultural technology,, 2004)This study was conducted in the northern part of Kenya, in Kakuma division, Turkana district. Kakuma is a semi- arid area under nomadic pastoralism as the main activity. The presence of a refugee camp has attracted many ... -
Effects of field conditions, low nitrogen and drought on genetic parameters of protein and tryptophan concentrations in grain of quality protein maize
(Department of Plant Science and Crop Protection, University of Nairobi, Kenya, 2008)Quality Protein Maize (QPM) has about twice the amount of lysine and tryptophan of normal maize and hence represents an important tool of correcting its deficiency in protein quality. However, the effects of low nitrogen ... -

Plant Species Diversity and Composition of Two Wetlands in the Nairobi National Park, Kenya
(Univesity of NairobiWangari Mathai Institute for Peace and Environment, 2012)Two wetlands (Hyena and Nalogomon) in the Nairobi National Park were investigated by comparing plant composition in and around their immediate vicinity. The most common aquatic plant species in the Hyena wetland was Cyperus ... -

Incorporation of green manure plants into bean cropping systems contribute to root-knot nematode suppression
(2008)Green manure plants were evaluated to determine their suitability as rotation crops with common bean to suppress root-knot (Meloidogyne spp.) nematodes. They were also evaluated as soil amendments in nematode control. The ... -
Impact of the invader Ipomoea hildebrandtii on grass biomass, nitrogen mineralisation and determinants of its seedling establishment in Kajiado, Kenya
(Univesity of NairobiWangari Mathai Institute for Peace and Environment, 2008)The invasive coloniser Ipomoea hildebrandtii aggravates the problem of inadequate grass forage in Kajiado district, Kenya. To test its impact on grass biomass, nitrogen (N) mineralisation and seedling establishment, grazing ... -
Influence of cultivation, settlements and water sources on wildlife distribution and habitat selection in south-east Kajiado, Kenya
(Univesity of NairobiWangari Mathai Institute for Peace and Environment, 2008)In Kenya, lands surrounding wildlife protected areas (PAs), referred to as dispersal areas, have undergone widespread land use changes, but these have been little studied. This study investigated impacts of different land ... -
