A global quantitative synthesis of local and landscape effects on wild bee pollinators in agroecosystems
(Blackwell Publishing Ltd, 2013)Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, we modelled the relative effects of ... -
The diversity of rural livelihoods and their influence on soil fertility in agricultural systems of East Africa – A typology of smallholder farms
(2010)Technological interventions to address the problem of poor productivity of smallholder agricultural systems must be designed to target socially diverse and spatially heterogeneous farms and farming systems. This paper ... -
Effect of Reduced Tillage and Mineral Fertilizer Application on Maize and Soybean Productivity
(2012)Reduced tillage is said to be one of the potential ways to reverse land degradation and ultimately increase the productivity of degrading soils of Africa. We hypothesised that crop yield following a modest application of ... -
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-10)The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ... -
Molecular genotyping of selected soybean (Glycine max L.) genotypes grown in different regions of East Africa
(2010)Soybean (Glycine max (L.) Merril) is one of the most popular pulses because of its protein content and nodulating ability. However, most farmers and researchers do not have sufficient genetic information of the genotypes ... -
Public perceptions towards genetically modified crops and foods in Kenya
(2009)The broad objective of the study was to assess public perception towards Genetically Modified (GM) Crops and Foods in Kenya. The specific objectives were to find out the influence of background factors and Agro-ecological ... -
Identifying Morpho-Physiological Characteristics Associated with Drought Tolerance in Selected Chikpea Germ Plasm in Nakuru and Baringo Counties, Kenya
(2013-11)tolerance based on a study of selected chickpea lines under field conditions in Nakuru and Baringo counties in Kenya. Drought has been spreading to more land in Kenya over the years due to climatic change attributed to ... -
Long-term effects of tillage, sub-soiling, and profile strata on properties of a Vitric Andosol in the Kenyan highlands
(2008)Tillage alters the structure and composition of soil aggregates affecting infiltration rate (IR) and hydraulic conductivity (K). This study investigated the long-term effects of conventional, minimum, and no-tillage with ... -
Utilization of proteins and nucleic acids in the study of gene function: a comparative review
(2010)Proteomics is one of the fastest growing areas in areas of research, largely because the global-scale analysis of proteins is expected to yield more direct understanding of function and regulation than analysis of genes. ... -
Additive main effects and multiplicative interaction analysis of genotype x environmental interaction among sweetpotato genotypes
(2009-04-08)Sweetpotato is an important food, feed and cash crop in Eastern Africa. Highly stable and adaptable genotypes are important in sweetpotato productivity and evaluation across sites would form a basis for breeding varieties ... -
Performance of sweet potato varieties across environments in Kenya
(2012-09)Sweetpotato is an important food, feed and cash crop in Eastern Africa but its adoption as a dual purpose crop has not been exploited. Varieties giving high tuber and vine yields would be ideal for small scale farmers who ... -
Novel source of sorghum tolerance to the African stem borer, Busseola fusca
(Academic Journals, 2012-08)Sorghum (Sorghum bicolor) is an important cereal food crop in semi-arid tropics, but its productivity is curtailed mainly by insect pests and diseases. The African stem borer, Busseola fusca Fuller (Lepidopteran: Noctuidae), ... -
New sources of resistance to spotted stem borer, Chilo partellus in sorghum
(2012)The lepidopteran Chilo partellus Crambid, an introduced pest in East and southern Africa from Asia, is the most economically important stem borer species infesting cereals in Africa. Chilo partellus causes more than 40% ... -

Identifying Morpho-Physiological Characteristics Associated with Drought Tolerance in Selected Chikpea Germ Plasm in Nakuru and Baringo Counties, Kenya
(2013-11)This paper examines the morpho-physiological characteristics of chickpea associated with drought tolerance based on a study of selected chickpea lines under field conditions in Nakuru and Baringo counties in Kenya. Drought ... -
Genetic diversity of Faidherbia albida (Del.) A. Chev accessions held at the World Agroforestry Centre
(Taylor & Francis, 2015-06)This study assessed the extent and distribution of genetic diversity of 29 Faidherbia albida provenances from 10 African countries by employing amplified fragment length polymorphism with an aim of providing crucial ... -
Genetic variability analysis for growth and yield parameters in double cross maize (Zea mays l.) genotypes in Kitale county of Kenya
(Science Journals Publishing, 2013)Present study was conducted to select hybrids with improved yield, to identify testers for grain yield and to determine the magnitude of genetic variability in maize hybrids for yield and its elements. Adaptability of ... -
Dissemination of Integrated Soil Fertility Management Technologies Using Participatory Approaches in the Central Highlands of Kenya
(Springer Netherlands, 2011-06)Declining soil fertility and productivity is a critical problem facing smallholder farmers in the central highlands of Kenya. A study to improve soil fertility and farm productivity within the smallholder farming systems ... -
