An electrophysiological study of spinal cord thermoreceptive neurones in the rat

Kanui, Titus I. (1983)
Maize yield estimation through the simulation of radiation penetration into the canopy

Musembi, David K. (1993)

It is essential for planning purposes to be able to assess or predict the output of vital crops in order to develop strategies to cope with shortfalls or surplusses with sufficient lead time. This is usually done by ...
The effects of irrigation, fertilizer nitrogen and planting density on bean (Phaseolus vulgaris) yield under different weather conditions.

Mburu, Mary W. K. (University of Reading, 1996)
An economic analysis of smallholder dairy productjon in Kiambu district, Kenya

Kilungo, Julius K. (1999)

The purpose of this study was to analyze the economics of smallholder dairy production in Kiambu District, Kenya. As high potential agricultural land sizes diminish in Kenya, it is critical that farmers attain high levels ...
Crop physiological analysis of seed quality variation in common bean (Phaseolus vulgaris L.)

Muasya, Reuben M. (2001)

Common bean yield is low in Kenya and use of poor quality seed by small-scale farmers has been identified as a major yield constraint. This research project aimed at increasing insight into development of common bean seed ...
Hydrodynamic processes, transport and flux of sediments in the Mwache creek mangrove wetland in Kenya

Kitheka, Johnson U. (2002)

This study was conducted in Mwache creek mangrove wetland (ca. 17 km2) situated within the Port-Reitz Ria in Mombasa District, Kenya. The aim of the study was to examine sediment and tidal water transport and exchange ...
The role of fish ponds in the nutrient dynamics of mixed farming systems

Muendo, Patricia N. (2006)

Rapid population growth in developing countries has resulted in increased demand for food, leading to increased pressure to extend land under cultivation and to intensify food production. Because most of the arable land ...
Legume crop-based soil phosphorus management and effects on maize (Zea mays) productivity in western Kenya

Kapkiyai, Jane J. (2008)

The low availability of phosphorus (P) in the oxisols of western Kenya is a major constraint to crop production. Some legume genotypes posses stress response mechanisms that enhance their ability to access P in low P soils ...
Response of benthic fauna to mangrove degradation and restoration in Gazi bay - Kenya

Mutua, Amos K. (2009)

The recovery towards a natural state of a restored Rhizophora mucronata mangrove ecosystem was investigated by assessing the sediment physical characteristics, densities, community composition and ...
The biology and ecology of Mussidia spp. (Lepidoptera : Pyralidae) and associated natural enemies in Kenya

Muli, Benjamin K. (2009-02)

Mussidia nigrivenella Ragonot (Lepidoptera: Pyralidae), an important pest of maize, cotton and Phaseolus bean in West Africa, has never been described as a crop pest from East and southern Africa (ESA). It was hypothesized ...
Expression of trypanotolerant quantitative trait loci in a boran-based backcross under natural tsetse challenge

Orenge, Caleb O. (2010)

African animal trypanosomosis (AAT) or Nagana is a transboundary disease with immense negative impact in Agricultural development across 37 African countries, with 60M livestock at risk. Utilization of trypanotolerant ...
Sociol-economic and agronomic factors influencing soil erosion in the Masinga Dam catchment, Kenya

Mutisya, Dorothy N. (2012)

This research examines agronomic and socio-economic factors influencing soil erosion in the Masinga dam catchments. The study addresses soil erosion from a human point of view as opposed to the common and widespread ...
Household energy consumption and dependency on common pool forest resources: the case of Kakamega forest, Western Kenya

Wambua, Stephen (2013)

Biomass is still the dominant source of energy used by most rural households in the developing world. Current use patterns have been linked to adverse effects on forest resources. Alternative fuels such as kerosene could ...
The influence of climate variability and change on Land-use and livelihoods in Kenya’s southern rangelands

Amwata, Dorothy A. (2013-07)

Climate variability and change are major challenges in ensuring household food security. However, there is a dearth of knowledge and information on the interactions between climate variability, land-use and household ...
Effects of irrigation, effluent dispersal and organic farming on earthworms and soil microbes in New Zealand dairy farms

Manono, Bonface O. (University of Otago, 2014)

The demand for increased food production has led to enhanced use of “external inputs” like chemicals, fertilizers, irrigation and effluent to boost yields. This has often been accompanied by unintended negative impacts on ...
Morphological, physiological and molecular characterization of drought tolerance in cassava (Manihot esculenta Crantz)

Orek, Charles O. (ETH-Zürich, 2014)

Cassava (Manihot esculenta Crantz) is inherently drought tolerant. Nevertheless, substantial genotypic variation exists for this trait. Characterization of these morphological, physiological and molecular ...
Indigenous knowledge and effects of integrated soil fertility management on growth, grain yield and rhizobia genetics of selected cowpea varieties

Kimiti, Jacinta M. (2014-12-02)

The main objectives of this study were; (1) To find out whether farmers in Makueni District were aware of soil fertility status in their farms and annual food availability, (2) To find out the proportions of cultivated ...
Evolution of Fish in Extreme Environments: Insights from the Magadi tilapia ( Alcolapia grahami )

Kavembe, Geraldine D. (Konstanz, 2015)

Cichlid fishes are well known for the ir spectacular adaptive radiations in the Great East African lakes. Yet, a number of reasons including their size, young age and recent ...
