Fertilizer Response and Environment Interactions of Yield and Yield Components of Clonal Tea (Camellia Sinensis) in Kenya
(International Society of Tea Science, 2019)
Tea is an important cash crop, providing income and employment to rural populations in many countries. In Kenya, tea is the leading export commodity crop and is grown in highlands east and west of the Rift Valley at altitudes ...
Seasonal and Environment Variations of Yields and Yield Components of Tea (Camellia sinensis) Cultivars in Kenya
(International Journal of Tea Science Vol 13, No. 1&2 (2017) : 10-24, 2017)
In Kenya, tea is grown in highlands east and west of the Rift Valley at altitudes ranging from 1300 m to 2700 m above mean sea level. These areas vary widely in seasonal and locational environmental factors leading to ...
Nitrogenous Fertilizer Rates and Plucking Intervals Effects on Soil Organic Carbon, pH and Tea Yields and Their Relationships in Eastern Africa Tea Growing Regions
(International Society of Tea Science, 2020)
Eastern Africa tea grows in high rainfall areas where nutrients depletion through leaching, and surface run-off can be high, in addition to removal with crop. Nutrients replenishment through fertilizer applications is ...
Clonal Variations in the Response of Hard Physically Withered Leaf to Rehydration Following Long Chemical Wither Durations
(International Journal of Tea Science Vol 13, No. 1&2 (2017) : 72-79, 2017)
Long chemical wither durations and hard physical wither reduce the quality of plain black tea, through reduction in total theaflavins production while encouraging thearubigins formation. Such quality reduction may vary ...
Clonal Variations in the Response of Hard Physically Withered Leaf to Rehydration Following Long Chemical Wither Durations
(The International Society of Tea Science, 2017)
Long chemical wither durations and hard physical wither reduce the quality of plain black tea, through reduction in total theaflavins production while encouraging thearubigins formation. Such quality reduction may vary ...
Applications of Active and Passive Sampling Techniques in Environmental Monitoring of Organochlorine Pesticides (OCPs) in Kenya
(www.iosrjournals.org, 2019-07)
This study evaluated the efficiency of using active sampling to estimate the environmental levels of bioavailable persistent organic pollutants (POPs) by introducing graded filters. Long-term passive sampling was combined ...
Yields and Nitrogenous Fertiliser Use Efficiency Responses of Clonal Tea (Camellia Sinensis) to Locations of Production
(International Journal of Tea Science Vol 13, No. 1&2 (2017) : 32-40, 2017)
Tea husbandry practices in Kenya are uniform despite variations in responses to agronomic inputs with locations. Nitrogen availability is the most limiting tea/crop growth factor. However, tea yields vary with region of ...
Sources, distribution, and risk assessment of organochlorine pesticides in Nairobi City, Kenya. Journal of Environmental Sciences, 96, 178–185
(Elsevier, 2020)
The distribution and sources of organochlorine pesticides (OCPs) in air and surface waters were monitored in Nairobi City using triolein-filled semipermeable membrane devices (SPMDs). The SPMDs were extracted by dialysis ...
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 ...
