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% ... -
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 ...
