Farming characteristics in urban districts of Nairobi county-Kenya.
(RUFORUM, 2014)Urban farming practitioners face challenges like lack of quality irrigation water, poorly decomposed manure, diverse inputs of unknown sources, unhealthy farm environment and abject poverty. All these contribute to production ... -
Characteristics of urban agricultural farming practices and spatial nature of production systems in the city of Nairobi, Kenya
(RUFORUM, 2014)Within the urban environment, urban agriculture faces myriad of challenges ranging from type of practices employed, through to production systems, to quality and safety of produce. An investigation was done to characterise ... -
Variant Surface Glycoprotein 4, a potential diagnostic candidate for the detection of Trypanosoma brucei rhodesiense infections
(Integrated Publishing Association, 2014)In the course of a Human African Trypanosomiasis (HAT) infection, there is a protracted and fluctuating course of parasitaemia during which different variant surface glycoproteins (VSGs) are expressed in a hierarchical ... -
Type and distribution of urban and peri-urban agriculture production systems in Nairobi County, Kenya
(RUFORUM, 2014)This research established the type and distribution of urban and peri-urban agriculture production systems in Nairobi County, Kenya. Results revealed that crops only were grown in Kamukunji district (58.8%) while ... -
A comparative evaluation of maturity indices of mango fruits produced in two contrasting agro-ecological zones of Kenya
(RUFORUM, 2014)Harvesting mango (Mangifera indica) fruits at the right stage for the destination market and use requires reliable maturity indices. There are various indices that are used to determine harvest maturity for mango fruits. ... -
The Influence of Compositional changes in Reconstituted Potato Flakes on Thermal and Dielectric Properties and Temperatures following Microwave Heating
(Elsevier, 2014)The objective of this study was to evaluate the effect of formulation changes on the temperatures of the reconstituted potato flakes following a standardised microwave reheating using a response surface method. Reconstituted ... -
Effects of the invasive tomato red spider mite (Acari: Tetranychidae) on growth and leaf yield of African nightshades
(Elsevier, 2014)The tomato red spider mite,Tetranychus evansi Baker and Pritchard, is one of the most serious pests of solanaceous crops in Africa. Field experiments were conducted to investigate its effects on the growth and leaf yield ... -
Growth and yield of tomato under alternate furrow irrigation in kibwezi, an “ASAL” area in eastern Kenya
(African Journal of Horticultural Science, 2014)Water saving irrigation technologies are key for crop production in arid and semi-arid lands (ASALs) considering the scarcity of water in these regions. A study was set up to test one such a technology, the alternate ... -
An assessment of the impact of pulsed electric fields processing factors on oxidation, color, texture, and sensory attributes of turkey breast meat
(Poultry Science Association, Inc., 2015)Pulsed electric fields (PEF) is a novel nonthermal technology that has the potential to cause physical disruption to muscle tissue which in turn could alter the sensorial aspects of meat in both a positive (e.g., enhanced ... -
Characterization of climate variability and water harvesting system for crop production in Adulala Watershed, Central Rift Valley of Ethiopia
(HARAMAYA UNIVERSITY, 2015)Scarcity of water is the most severe constraint for traditional agriculture in semi-arid areas of Ethiopia. Precipitation is extremely variable, thus water harvesting is crucial for ensuring improved crop ... -
