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 ... -
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 ... -
5 Infrared Drying
(CRC Press, 2010-07-26)This chapter will present the mechanism, techniques, and advantages of infrared (IR) drying for various food and agricultural products. The propagation of IR radiation from a source (considered as any material at a ... -
Diallel analysis of Snap bean (Phaseolus vulgaris l.) varieties for important traits
(Academic Journals, 2010-08-04)The breeding programmes of many crops use diallel analyses because of the genetic information they offer to breeders. Six morphological and agronomic traits of Snap bean (Phaseolus vulgaris L.) were studied to investigate ... -
The Utility of Aerial Pan-Trapping for Assessing Insect Pollinators Across Vertical Strata
(2011)Insect pollinators provide a critical ecosystem service by pollinating many wild flowers and crops. It is therefore essential to be able to effectively survey and monitor pollinator communities across a range of habitats, ... -
Sensitivity of microscopy compared to molecular diagnosis of p. Falciparum: implications on malaria treatment in epidemic areas in kenya
(2011)Detection of Plasmodium species by microscopy has been the gold standard for diagnosis of malaria for more than a century. Despite the fact that there is a significant decline in the number of positive cases reported from ... -
