A study of yield characteristics during mechanical oil extraction of preheated and ground soybeans
(2007)Soybeans were extracted for oil by compressing a ground sample at various operating pressures, pressing durations and product bulk temperatures. The oil yield from the various operations was measured and expressed as a ... -
Research trends in modeling, optimization and control of the drying operation
(2007)Drying food is an extremely sensitive operation that requires the proper monitoring and control of the heating medium temperature as well as the length of time that the product is exposed to this temperature. Since the ... -
Effects of organic and mineral fertilizer inputs on maize yield and soil chemical properties in a maize cropping system in Meru South District, Kenya
(Springer, 2007-01)Soil nutrient depletion as a result of continuous cultivation of soils without adequate addition of external inputs is a major challenge in the highlands of Kenya. An experiment was set up in Meru South District, Kenya ... -
Evaluation of the effect of ripening on the sensory quality and properties of tamarillo (Cyphomandra betaceae) fruits
(Elsevier, 2007-03-31)Tamarillo (Cyphomandra betaceae) fruits were sourced from a single farmer from the Central province of Kenya soon after harvesting. The fruits were then cleaned and sorted in order to remove all immature and damaged fruits. ... -
Potential of nightsky nocturnal radiative cooling as a fresh produce preservation method
(2007-07-30)Abstract: The change in water temperature in horizontally placed pans exposed to the night-sky radiation was monitored at night between the hours of 8:00pm and 6:00am. The effect of varying the quantity of water in the pan ... -
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 ... -
Agronomic Performance of three most Popular Commercial Watermelon Cultivars in Kenya as Compared to one newly introduced cultivar and one local Landrace grown on Dystric Nitisols under Sub- Humid Tropical Conditions
(Asian Research Publishing Network (ARPN)., 2008-11)Agronomic performance trial involving five cultivated watermelon accessions available in Kenya was conducted at Maseno University Research Fields for two seasons between year 2007 and 2008. The accessions included three ... -
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 ... -
Collembola Richness and Diversity along A Land-Use Intensity Gradient in Taita, Kenya
(2009)Soil Collembola communities were sampled along a gradient of land use intensification in Taita-Taveta, Wundanyi division, Coast Province during the wet season (October-November 2007) and dry season (February- March ... -
Collembola Density and Diversity along a Gradient of Land- Use Types in Embu District, Eastern Kenya
(2009)Populations of soil-dwelling Collembola were monitored on a land use gradient ranging from Natural forests to intensively cultivated land during the wet season October-November, 2007 and dry season February-March, 2008. ... -
Analysis of Fish Fillet Drying Rates under Three Solar Energy Drying Systems
(2009-02-20)A small Box type solar dryer with controllable air inlet was designed and tested. The dryer had a mild steel absorber plate and a polyvinyl chloride (pvc) transparent cover and could be adjusted to allow variation in airflow ... -
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 ... -
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 ... -
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. ... -
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 ... -
Yield of three Commercial Watermelon Cultivars in Kenya as compared to a local landrace
(2010)High yield is a major goal for watermelon (Citrullus lanatus) breeders. The objective of this study was to measure the yield potential of some watermelon accessions available in Kenya and identify high yielding ones for ... -
Morphological Characterization of Five Newly Developed Lines of Arabica Coffee as Compared to Commercial Cultivars in Kenya
(ACADEMIC JOURNALS, 2010)Five new lines of Arabica coffee and two existing commercial cultivars planted in the field were characterized morphologically. The objective of this study was to determine the level of morphological variation within and ... -
Genotype variant of soybean cultivars around Lake Victoria region, East Africa
(2010-01)Glycine gracilis, which originated from North-East China, is morphologically intermediate between the cultivated G. max and the wild form, G. soja. These three forms are cross-compatible and their crosses provide a resource ... -
