Comparative Economic Analysis of Clonal Tea Yield Response to Nitrogen Fertiliser Rates within Selected Geographical Areas in Kenya
(INTERNATIONAL JOURNAL OF TEA S, 2020)
Tea sector contributes approximately 30% of export earnings in Kenya. Despite the industry continuing to realize positive gross margins,
high costs of production coupled with weak trends in export prices threaten its ...
Bioactive carbazole alkaloids from Alysicarpus ovalifolius (Schumach)
(The Korean Society for Applied Biological Chemistry, 2015-12-01)
Phytochemical and biological evaluation of the stem bark of Alysicarpus ovalifolius led to the
isolation of three carbazole alkaloids identified as mohanimbine (1), koenimbine (2) and
koenidine (3) along with quercetin ...
Ursane and tirucallane-type triterpenes of Boswellia rivae oleo-gum resin
(Taylor &Francis, 2016)
Two new ursane-type triterpenes characterized as 3-oxo-24-acetoxy11α-hydroxy-urs-12-ene (1) and methyl 3α-acetoxy-11α-methoxyurs-12-en-24-oate (2), together with known compounds 3–11,
were isolated from Boswellia rivae ...
Analgesics from Lonchocarpus eriocalyx Harms
(Islamic Azad University, Shahrood Branch Press,, 2018-12-15)
Four lupane-type terpenoids, namely lupeol (1), friedelin (2), stigmasterol (3), and stigmasterol-3-O-glucoside (4) were isolated from the ethyl acetate extract of leaves of Lonchocarpus eriocalyx Harms. These compounds ...
Effects of regional climate variability on the prevalence of diseases and their economic impacts on households in the Lake Victoria basin of Western Kenya
(Inderscience Publishers (IEL), 2016)
Climate variability has a strong influence on disease prevalence and subsequently on
economic wellbeing of the affected households. In this study, six regions were selected and

Response of Clonal Tea to Different Tea Growing Locations, Nitrogenous Fertiliser Rates and Plucking Intervals in the Kenya Highlands
(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 ...
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 ...
