Improved biodegradation of 1, 2, 4-trichlorobenzene by adapted microorganisms in agricultural soil and in soil suspension cultures
(Elsevier, 2011-08-01)Inoculating soil with an adapted microbial community is a more effective bioaugmentation approach than inoculation with pure strains in bioremediation. However, information on the potential of different inocula from sites ... -
Improved biodegradation of 1,2,4-trichlorobenzene by adapted microorganisms in agricultural soil and in soil suspension cultures
(Pedosphere, 2011)Inoculating soil with an adapted microbial community is a more effective bioaugmentation approach than inoculation with pure strains in bioremediation. However, information on the potential of different inocula from sites ... -
In Vitro Permeation of Mesembrine Alkaloids from Sceletium tortuosum across Porcine Buccal, Sublingual, and Intestinal Mucosa
(Planta Medica, 2012)Sceletium tortuosum is an indigenous South African plant that has traditionally been used for its mood-enhancing properties. Recently, products containing S. tortuosum have become increasingly popular and are commonly ... -
Influence of anthropogenic activities and seasons on heavy metals in spring water along Amala and Nyangores tributaries of the Mara River Basin
(Academic Journal, African Journal of Environmental Science and Technology, 2018-07)Anthropogenic activities, including replacing natural forests with human settlements and increased agricultural activities have environmental impacts. The activities can contaminate aquatic ecosystems including spring ... -
INFLUENCE OF AREA OF PRODUCTION, NITROGENOUS FERTILIZER RATES AND PLUCKING INTERVALS ON THE PRODUCTION OF FATTY ACIDS IN CLONAL TEA (Camellia sinensis (L.O) Kuntze) LEAVES
(Maseno University, 2010)Tea, Camellia sinensis, is widely grown in the highlands of Kenya for manufacture of mainly black tea. The most costly inputs in tea cultivation are nitrogenous fertiliser and plucking which are key determinants of yield ... -
The influence of geographical area of production and nitrogenous fertiliser on yields and quality parameters of clonal tea
(2010-04-01)Variations in requirements for tea production in Kenya and factors controlling growth and production of secondary metabolites responsible for the quality parameters are indicative of the need for non-uniform recommendations. ... -
Influence of Geographical Area of Production on the Caffeine and Flavan-3-ol Profiles of Selected Clonal Green Tea Leaves from Smallholder Tea Farms in Kenya
(International Society of Tea Science, 2019)Despite the use of similar cultivars in the smallholder tea sector in Kenya, resultant black tea quality varies. These variations could in part be arising from the formation of varying quantities and ratios of the black ... -
Influence of land use practices on water physicochemical parameters and nutrients loading along the Mara River of East Africa
(AcademicJournal, African Journal of Environmental Science and Technology, 2018-07)Mara River originates from the Mau Forest and traverses through landscapes with varying activities. Over the years, Mara River Basin has witnessed population increase, accompanied with conversion of forestlands into ... -
Influence of Location of Production, Season and Genotype on Caffeine and Flavan-3-ols in Young Green Tea (Camellia sinensis) Leaves in Kenya
(David Publishing Company, 2013)Although tea is grown in agro-ecological regions widely varying in environmental factors affecting yield and quality, planters usually import genetic materials across the different growing regions assuming genotypes with ... -
Influence of Nitrogen Fertilisation on Red Spider Mites (Oligonychus coffeae Nietner) and Overhead Volatile Organic Compounds in Tea (Camellia sinensis)
(International Journal of Tea Science Vol 13, No. 1&2 (2017) : 52-59, 2017)Nitrogen fertilisation influences tea yields, quality and pests infestation levels. Red spider mites reduce tea production in western Kenya during prolonged droughts. Nitrogen fertiliser use maybe an agronomic practice ... -
Influence of nitrogen fertilizer rates and harvesting intervals on the clonal tea green leaf fatty acids levels in the Lake Victoria Basin of Kenya
(CABI, 2011)Tea agronomic recommendations in Lake Victoria basin are uniform, despite different regions producing teas of different qualities and yields. It is not known if these differences arise from variations in cultivars, agronomic ... -
Influence of Nitrogenous Fertilizer Rates and Plucking Intervals on Tea in Peatland and Highland Ultisol Soils of Rwanda: 1 Tea Yields
(International Journal of Tea Science, Volume 15 Issue 1 (2020, 2020)Tea in Rwanda, is grown in different agro-ecosystems comprising highlands and drained low elevation peatlands. The plantations use uniform agricultural practices imported from Eastern Africa countries, but without re-testing ... -
Influence of region of production on clonal black tea chemical characteristics
(2008-05-01)Production of black tea from the same vegetatively propagated (VP) cultivars, in Kenya and Malawi, shows variations in both chemical composition and quality. Whereas it is possible to produce black teas with similar ... -
Influence of region of production on relative clonal plain tea quality parameters in Kenya
(Elsevier, 2010-04-01)Tea is grown in diverse regions with varying climates. Growers seek high-yielding and superior quality cultivars to improve profitability of the enterprise. A superior quality genotype in one location is assumed to ... -
