An overview of advances in bioinformatics and its application in functional genomics
(2010-04-28)Bioinformatics is the scientific discipline that is concerned with the efficient management and useful interpretation of large scale biological information. Functional genomics aims at mapping DNA sequences and the ... -
A perspective on proteomics: current applications, challenges and potential uses
(Academic Journals, 2010-08)Biological sciences are experiencing an ongoing information revolution. Proteome-wide functional classification using bioinformatics approaches is becoming an important method for revealing unknown protein functions. ... -
Determinants of Electronic Health in Developing Countries
(2014-04)Limitations of paper-based records are influencing a transition across the globe towards Electronic Health Records (EHRs) and in general electronic health (eHealth). However, despite the well documented benefits of eHealth, ... -
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 ... -
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 ... -
Rainfall Variability, Drought Characterization, and Efficacy of Rainfall Data Reconstruction: Case of Eastern Kenya
(Hindawi Publishing Corporation, 2014-08)This study examined the extent of seasonal rainfall variability, drought occurrence, and the efficacy of interpolation techniques in eastern Kenya. Analyses of rainfall variability utilized rainfall anomaly index, coefficients ... -
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 ... -
The Potential of Organic and Inorganic Nutrient Sources in Sub-Saharan African Crop Farming Systems
(2012-02)he Potential of Organic and Inorganic Nutrient Sources in Sub-Saharan African Crop Farming System -
Predicting decomposition patterns of tree biomass in tropical highland microregions of Kenya
(Kluwer Academic Publishers, 1997)Decomposition- and nitrogen-release patterns of biomass from three agroforestry multipurpose trees (Calliandra calothyrsus, Cordia africana and Grevillea robusta) were investigated in four contrasting environments ... -
Decomposition of Cassia siamea loppings in semiarid Machakos, Kenya
(1994)The rate of decomposition of Cassia siamea Lam. prunings in an alley cropping system was investigated using litter bags in the semiarid area of the Machakos District, Kenya, during the short rains of 1988 and the long rains ... -
Alley cropping of maize with calliandra and leucaena in the subhumid highlands of Kenya Part 2. Biomass decomposition, N mineralization, and N uptake by maize
(Kluwer Academic Publishers, 1999-06)A major challenge in developing agroforestry approaches that utilize tree-leaf biomass for provision of N to crops is to ensure synchrony between the N released from decomposing prunings and N demand by crops. A study was ... -
Soil Inorganic N and N Uptake by Maize Following Application of Legume Biomass, Tithonia, Manure and Mineral Fertilizer in Central Kenya
(Springer Netherlands, 2011-05)In the smallholder farms of central Kenya soils suffer from nitrogen (N) deficiency due to inability to replenish it through application of chemical fertilizers and/or manure. This study evaluated the effect of some ... -
Soil fertility under Calliandra calothyrsus hedgerows and other land-use treatments following forest clearance in Jamaica
(Kluwer Academic Publishers, 2003-02)An experiment in the Blue Mountains of Jamaica investigated the consequences of three land-use treatments applied following forest clearance on soil fertility and resulting crop growth over a five year period. The treatments ... -
Soil fertility status, management and research in East Africa
(2004)This study reviews and synthesizes the soil fertility status, management among smallholder farmers and research in the three countries of east Africa, namely Kenya, Tanzania and Uganda. We observe that many studies note ... -
Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya’s Central Highlands
(Springer Vienna, 2015-03)Drier parts of Kenya’s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding ... -
Nitrogen recovery by alley-cropped maize and trees from 15N-labeled tree biomass in the subhumid highlands of Kenya
(Springer-Verlag, 2000-05)The effectiveness of tree-leaf biomass as a source of N to crops in agroforestry systems depends on the rate at which crops can obtain N from the biomass. A study was conducted to determine the fate of 15N labeled, ... -
Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with inorganic nitrogen source in Central Kenya
(Kluwer Academic Publishers, 2004)Decline in crop yields is a major problem facing smallholder farmers in Kenya and the entire Sub-Saharan region. This is attributed mainly to the mining of major nutrients due to continuous cropping without addition of ... -
Evaluation of Leucaena leucocephala as a source of N for maize
(1997-01)Prunings of leucaena [Leucaena leucocephala (Lam.) De Wit] have long been regarded as a useful alternative to N fertilizer, but N use efficiency by crops is often low. The potential exists to synchronise nutrient ...
